Still good to have a pin

[vivid moon]

People have been begging for 5:3 for a while, and then it just shows up

[unborn marsh]

Have one. Screen is great. Buttons are stiff. Stripped a screw just trying to open it up. Lol. But I'll eventually drill it out and put it back together 😆

[hoary cedar]

It is quite stiff yea, probably needs a rubber swap

My d-pad used to be as stiff but got softer not sure how

[unborn marsh]

Haha. Maybe I just need to break mine in. Wanted to get a pic of the internals and ended up bending the back out of the way. So without drilling it out it's basically unplayable

[vivid moon]

Stiff and able to break it in isn't the worst situation

[robust ridge]

I'll try getting one now that it's on Pinduoduo (Also OP, you may want to check your spec sheet)

Are you trying to tell me that they lied in their Ali express listing?

[final saffron]

Lol, shocking I know. Also the listing says it has an AK3326 processor

[vivid moon]

https://tenor.com/view/kermit-kermit-the-frog-bruh-smiling-drive-gif-5828717602637718027

[lost sky]

Also, it packs a USB C to USB A cable, so listing USB C to C is also a lie

[hoary cedar]

I asked them about it they’re insistent its an AK3326 even after showing the chip 🤣🤷‍♂️

only AK i know is 47

[final saffron]

In their defense, R and A look pretty similar. Ask me to tell the difference between 未 and 末 and you'll get the same result.

[hoary cedar]

[unborn marsh]

lol, well, this thread inspired me to finally drill it out

we back in business baby

gonna order some replacement torx

[hoary cedar]

Oh shit this one’s screw is torx?

[unborn marsh]

no, they're shit philips head

i just replace everything with torx

lol

[hoary cedar]

Ah made me panic I don’t have torx 🤣

[robust ridge]

Torx is like the Anbernic bits right?

[unborn marsh]

haha, yeah, i come from the custom keyboard world, so i have torx and hex all over

those guys

almost impossible to strip, wish more companies used them, or at least hex at a minimum

[robust ridge]

Well, no hex plz

[hoary cedar]

anbernic uses hex

[robust ridge]

I have RG351V and a hex driver

[unborn marsh]

i mean philips + chinesium = strip

[robust ridge]

Its hex screws can strip too

[hoary cedar]

They go round 😀

[unborn marsh]

i always assume whenever i take one of these part i'm stripping it, and that's being slow and methodical, lol

[hoary cedar]

Torx probably is better

[unborn marsh]

it offers the best grip on shit metal

[robust ridge]

I think I once encountered broken torx holes too

[unborn marsh]

yeah, it can def happen

[robust ridge]

If metal is too soft

No screw slot shape can help

[unborn marsh]

it's just the least likely, but somehow they make screws out of something softer than aluminum so

you can tell when you drill them out, and you almost go through the whole system with barely any pressure

[robust ridge]

Thankfully they're still mostly ferrous at least

[hoary cedar]

how about robertson (square)

[unborn marsh]

anyway, i'm ordering some from mcmaster-carr, so if they work i'll drop a link here

[hoary cedar]

or the triangle ones that mcdonalds use for their toys

[unborn marsh]

lol, i actually have a bit for those, think it came with one of those ifixit mega kits

[hoary cedar]

That would be next level shit to release a retrohandheld with mystery scraped off chip and impossible screws 🤣

[robust ridge]

I don't really like having all the different screw slots

My everyday carry has a screwdriver

It's not magnetized which means one day I'll change it out

The one currently has phillips

[unborn marsh]

eh, they have their place

[robust ridge]

The moral of the story

Use harder metals plz

[unborn marsh]

like when doing small hardware with small screws you really should be using hardened steel with a good head shape, like philips and flathead is fine for like farming machinery, lol

but they're just scheap

it's easy to machine, pretty sure on softer metals they just stamp the philips pattern in

it wouldn't matter if when putting these together they didn't torq the shit out of them, but it is what it is

[hoary cedar]

https://youtube.com/shorts/n19ueZgddYo?si=XSlYI66dt2_6_h98

[unborn marsh]

well these worked, just some steel M2 8mm screws i had lying around, tightened up nice, can now open it XD

[hoary cedar]

They do 🤣

[unborn marsh]

haha, hell yeah

like they're sealing airplane exit doors (non-boeing)

[carmine sierra]

Community image? Any problems thusfar?

I was eyeing one, if ArkOS runs without trouble, this one is a steal at $28

[hoary cedar]

Need a little time to check but probably same controls issues with the r36s clones. Should be easily remapped.

[final saffron]

That extra 160 pixels goes a long way

Gorillax seems confident that’s the brand, and I believe him

[hoary cedar]

I can confirm

I think it's another brandless thing where JIFEIMAN might just be a badge

The only seller I found on 1688 is 凯旭达

Hey

Does it really seem like the U8 has much less polish than the regular R36S including with the D-pad?

I know the clone R36S has a much worse D-pad

[hoary cedar]

The clone R36S has worse

My clone r36s dpad sometimes needs two press to register

[hoary cedar]

weird color 🤣

[carmine sierra]

Is it just in that rom?

[hoary cedar]

Nope, I forgot to add the new filter files maybe

[solemn tapir]

release date arkos for U8

[hoary cedar]

not until i figure why the color looks like that xD

[wild condor]

I'm new to these Chinese handhelds. This happened either after I put the SD card in my computer or I put a 2nd SD card in the TF2 slot.

Now it's a paperweight right now 😑

[unborn marsh]

Yeah. I kept the original SD off to the side before I did crazy things. Lol

[final saffron]

Heh, yeah bundled sd cards are read-once

[quick ravine]

Can you still acces the psrtitions on a PC?

[wild condor]

Yeah. I can still access the roms and system partitions of the SD card from my computer.

[quick ravine]

Ok, so I am not sure what your issue is. But if I were you I would download the emuelec image for the k36 hosted at miraheze (preferably the one uploaded by aeouluuX), flash it into a new card, and manage to then replace the emuelec partition files with the ones on your og card (and then copy the roms to the eeroms partition). The problem with this is thay you will need to keep the extlinux folder from the k36 image, and the files there make reference to a dtb with a different name. So you might have to either rename the dtb or edit the files in the extlinux folder with the dtb file name of the og U8. If you are new to RH it might be a bit too complicated.

[quick ravine]

Ok, so I just tried. You have to copy the entire emuelec partition from your og card except the extlinux folder files. And you have to edit the exlinux folder files with the correct dtb name.

[wild condor]

I really appreciate your help! 🙏But this method didn't work for me. When I try to turn the device on. Nothing happens. Not even a light shows up.

my steps were:

copy all the files except the extlinux folder to the partition
copy the "rfk38g3sa.dtb" file to the partition than rename it to "rk3326-evb-lp3-v12-linux.dtb". Then boot the sd card on the device.
This didn't work so copied the dtb file again without changing the name. And then edited the .conf files in the extlinux folder in notepad to change the line to "FDT /rfk38g3sa.dtb."

I also tried the ArkOS install method by flashing it on my SD card and replacing the dtb file with the one provided in the old thread. It boots but with the weird rotated screen issue.

I might just let this thing stay a "paperweight" right now until Ark or something is released for it. I guess this is the "danger" of buying a new handheld without a lot of community support yet 😆

[hoary cedar]

I might have figured out the retroarch issue so if all goes well ArkOS will be up tonight 🙂

[oblique void]

Link

[quick ravine]

Ok. So i think you got a step wrong. 1) flash the image 2) delete all contents from the emuelec partition except the extlinux folder 3) copy all files from the emuelec partition of the og card (except exlinux folder) to the new flashed emuelec partition 4) open the files in the the exlinux forlders and renaname the dtb mentions (from rk3326.... to rfk...). 5) rename the file in the exlinux folder called rk3326.....config to rfk38.....config. This way you will have the OG card files and the extlinux files will be redirecting to the right unit partitions.

At first it might seem like it isnt loading because it doesnt show the boot images

I am guessing that if once you get it to work you delete all the storage contents, then on the next load it will copy all the og files from the system file.

[hearty iron]

I was gonna suggest that a thread be added for the u8 since I plan to get one as well, it honestly looks solid, glad to see it's here

[ancient ridge]

AeolusUX brings new life to another device!

power button sleep works only 1 time and it returns black screen after that. i tried various combination with dsi,format/lane and clock-frequency, only the original(emuelec) values make sleep work again (dis,format=<0x00> / dis,lanes=<0x02> / clock-frequency = <ox1c9c380>. but it makes the screen 66hz instead.

[hoary cedar]

I’ll try and return the frequency. Damn I thought it was because its a 351p clone 🤣

[ancient ridge]

and right stick is inverted(it's not important tho). do you know how to invert axis on arkos-mod? 'invert-absx/y/rx/ry' doesn't work here

same problem on rx6h

[hoary cedar]

may just need to make a new es_input.cfg and configure them on retroarch and standalone emulators

[ancient ridge]

seems no choice but to modify it one by one

[carmine sierra]

What does this mean for portmaster joystick mapping?

[final saffron]

You might have to edit the gptk files for each game.

[hoary cedar]

Should I just make first boot like this?

[junior bear]

yes please

[quick ravine]

Yesss

[robust ridge]

Does it play two boot screens one difectly after another?

[hoary cedar]

Yea 🤣

[solemn tapir]

I got the device.

The buttons are quite hard.

[hoary cedar]

Give it time you’ll either get used to it or it will break in 🤣

Arkos stable release date

[final saffron]

Yesterday, unless you found bugs

[robust ridge]

If I were on a harder handheld binge (as if I'm not in one right now) I might order a whole pack of Anbernic membranes and just put them in any of these linux handhelds as long as I can be sure they're compatible by myself

[ancient ridge]

the controller of u8 is garbage, but it's a lot better after I replaced the membrane with R36s' which is the same size. (left:U8 / right:R36s)

[solemn tapir]

screw is bugs

[hoary cedar]

@unborn marsh warned us

haha, yeah man, have dremel prepared XD

[hoary cedar]

Did you replace sd cards?

[solemn tapir]

Yes i replace Kingston sd card

[hoary cedar]

I don't think it's a bug how do you save? My saves and savestates are fine...

[deep tundra]

imagine being so bad that r36s membrane is an upgrade

[hoary cedar]

Miyoo Mini Plus Membranes would make this so good

Found some on my handheld graveyard 😏

[solemn tapir]

can not open 555

[robust ridge]

Is there a way to kinda just make the rubber pads a little softer by yourself?

I know someone thought of putting tied-up and crooked cable in hot water and something to essentially make them go straight again

[vale bay]

👍

[kind drift]

This menu music is

[quick ravine]

It's the music from the k36 and emuelec clones. I copied it to my emuelec tv box xD

[solemn tapir]

Do you have any rubber pad
recommend ?

[shadow flare]

Wait when did you buy this

[carmine sierra]

Just received 2 U8's. IMHO some very disappointing build-quality on both my units. Some buttons barely register, unless you ram down on the them. Dpad's same issue. These buttons are far worse than any other retro handheld that I have owned or used.. 😦

I guess I will be returning both units. I'm okay with doing software tinkering. But having to tear down a device physically, just to make it playable.. Well that kind of takes the fun out of it for me.

[kind drift]

https://tenor.com/view/i-dont-think-you-want-people-answering-that-question-annie-murphy-alexis-alexis-rose-schitts-creek-gif-20853852

[hearty iron]

Banger music indeed

[hearty iron]

That's really bad luck I think, since the review I saw on it mentioned how the buttons were solid. That's really unfortunate that it came in that condition

[unborn marsh]

Oh their solid. Like rock solid. Lol

Think that's not a conditional thing. They're just hard to actuate compared to any other device I've used. Can maybe fix it by replacing the membrane?

[carmine sierra]

It's more of a workout device this way lol

[unborn marsh]

Haha. True that. I mean it's playable for me. But def not as nice as other more expensive devices in this one regard

Id also call them not comfortably rounded. They have an edge to them that may be the reason you really have to push down from the top to get them to trigger

[hoary cedar]

It gets softer or you could replace them if you still don't like them after

or i just got used to it

[hearty iron]

I am used to cheaper handhelds so it may not be as bad for me, at least I hope not, since I do really want to invest in one, and there's no real way to measure how hard it is to input without having it in my hands I feel

[carmine sierra]

I have over 10+ different handhelds. The U8's buttons are the worst I have had to deal with yet 🤷‍♂️ But maybe it's just me

[quick ravine]

I have 2 of them and both have different letter buttons that need to be pressed harder. They also have the ocasional input misdetection issue, which doesnt help. Next week I will try opening one and see if I have any other rumber membraines that fit and I will also try to ad conductive stickers to try to fix the misdetections.

[solemn tapir]

I need boil rubber pad 🤣

[carmine sierra]

Let us know how this works out lol 😉

[solemn tapir]

I think feeling is ok after boil 🤣

[hearty iron]

ooo I am curious to see your collection

I am lowkey addicted to these no-name handhelds bc for the price to performance you find some real hidden gems. GB300 is an example of a dirt cheap device that is definitely far from good on it's own but when it's under 10 dollars, it beats the hell otu of a famiclone

[carmine sierra]

Will send you a message later on!

[hearty iron]

bet :)

I can show you my collection as well

[robust ridge]

Membrane issue? Did people replace them with Anbernic ones? Or did...

[regal lion]

Hi everyone I have a U8 and yesterday when I inserted the second TF2 sd I get the error that it does not detect systems. the sd is not corrupted and I saw that in storage/.config/emulationstation/es_systems.cfg there is the folder that goes to read and it is /storage/roms where I inserted a game for psx and it worked. But the point is that before having inserted I did not need this because I have a much larger partition called eeroms, with all my roms, which is no longer read. which I decide to remount it in autostart.sh and custom-start.sh but nothing, it does not even create the logs. So I try with symbiotic links but nothing.. I do not know what to do anymore and I would like to understand how to manage the situation. So I can install Arkos thanks to you but I would also like to recover the original stick, in case you have a backup? Or can you explain to me what is happening? thanks a lot

[sudden cargo]

the same thing happened to me. i restored to stock os and just use 1 tf slot

[reef gate]

I've kept an eye on this handheld because of the screen size and price but was put off because it's the same size as an TSP. Would anyone recommend this over a TSP for GBA?

I already have a TSP

[hoary cedar]

Integer scales perfectly for GBA

5:3 screen ratio

[reef gate]

if it wasn't for the buttons i would've bought one. I hate stiff buttons. I have an R35s. Would you say that the buttons are better?

[reef gate]

If the 34xx wasn't 70 I would get that. I am looking for the cheapest GBA machine. Currently I'm using the A30 for gba but it doesn't feel good. The TSP is good but too squeaky. I have verticals but would prefer horizontals

[hoary cedar]

Worse

[reef gate]

lol dang

[carmine sierra]

My TSP is a so much better product overall.. I've had to send my 2 U8's back for refund due to the quality being abysmal. There is no comparison between the TSP and the U8 in any aspect IMHO. Especially since the TSP has made leaps forward in the CFW department, I would never recommend you the U8 over it.

[final saffron]

Tsp screen hits way above its price. Integer scaling GBA isn't necessary on 1280x720

[hearty iron]

I can more or less agree with this, the only benefit of the u8 is the price is lower. If you ever see a TSP in the low 40s and can grab it instead, it's gonna be an all-around improvement

[hearty iron]

deffo

[final saffron]

Cheapest I can find u8 shipped is $30... Tsp is $55. They're much different price points. Compare U8 with batlexp or r36s

[hearty iron]

I know the tsp is much more expensive, everyone was comparing it to the u8 so I just wanted to point out the price gap

you can almost buy 2 u8s for the price of a tsp

and you don't get double the performance either (but the creature comforts might be well worth it)

I managed to get It for only 10€

Just after I bought It the price changed to normal, 40€

How powerfull is this thing? How It compares to other consoles?

[junior bear]

Up to some of psp game, and some of dreamcast game.

[ancient ridge]

[balmy wind]

Oh is compatible with Moonlight or Steam link?

[hearty iron]

SHEEEEESH how'd you manage that? that's hella cheap

[hearty iron]

pffff what- how are you game streaming with it? I am curious

[ancient ridge]

yes, portmaster-moonlight new

[hearty iron]

ooo gotta look into that when mine gets here

[quick ravine]

Early bird price

[final saffron]

Yeah early bird price is when new retailers carry a thing they set the price low to get purchase numbers up. You're sorta taking a risk that it's a scam but also it really does happen for most retailers and since the U8 is a bit obscure it's probably legit.

There were a ton of $10 U8's a few weeks ago as all the retailers started carrying them

[quick ravine]

Yeah somethings similar occurred with the rx6h, but prices didnt drop as much

[final saffron]

Yeah, the Batlexp didn't do it at all because Ampown is a big seller so they just carried it full price

[quick ravine]

I actually ordered an early bird g350 yesterday, but the price only dropped to 35 euros. I waited till the last moment hoping for a U8 situation.

[final saffron]

Just looked and sure enough... Picked up a U8 for $20usd

[hearty iron]

sheeeesh good shit fr

[hearty iron]

I wish I capitalized 😭

[hearty iron]

damnnn that's amazing

I couldn't find one for that price when I ordered mine just last week, I got mine RIGHT in between sales 😔 but I am not regretting paying 33 for it, it's well worth it

my observations from my very brief handling:

that startup time is REAL slow, like I think it might even be slower than the m17 was, but hey at least it has a sleep mode unlike the m17

it did NOT wanna power back off once I turned it on lol, had to hold it down like 6 times for it to work (and like 8 seconds at that when it did)

it has the most groovy menu music of any handheld I've owned up to this point. seriously, it's SOOO fun to listen to.

it has a pretty solid screen, build quality isn't bad either but the way the screen sticks out definitely concerns me

it's a LOT bigger than I thought it would be, I am not complaining tho, I will have no issues seeing the games I play. I gotta test it out more tho for sure

also replacing the sd card with one that is branded might solve the issues of load times

this is also my first handheld with 2 sd card slots, how does the second one normally work?

[final saffron]

Depends on the OS but generally you format the second SD as exFAT. I think there's a menu option in many firmwares to format and build the directory structure. Then you can just copy the game SD around and swap in OS sdcards if you wanna change OS

[hearty iron]

U8 has emuelec that is skinned like arkos out of the box, I know arkos exists for it but if I find emuelec to be properly featured then idk if there's a point in me switching over

is there any particular benefit to having 2 slots versus one?

other than having more game storage lol, which would be great but for something low end like the u8 idk if it's worthwhile in that regard, a 128gb card (256 at most) should house every gme this thing can run most likely

and I can attest, these buttons are STIFF, not as bad as I thought they'd be, but definitely stiff

might be able to break them in tho

[final saffron]

If you ever do want to upgrade your OS, it can be really nice having a games card. Often new OS installs prefer a wiped card and then you lose all your save games.

[hearty iron]

that's true, although I normally do sd card copies on my computer as well, but I see the convenience in having a game card

[hearty iron]

I can more or less confirm that the buttons WILL become less stiff over time, I had to do some minor button mashing but my B button has gone from almost unplayably stiff (I didn't realize how bad it was until I tried to play mario world) to quite usable but still a bit hard

it's still a bit rough but not NEARLY as bad, if anyone is having stiffness issues, just mash the buttons a bit, honestly test your might in mortal kombat might be amazing for this LOL

[hoary cedar]

Yea mine feels like my r36s now lol

[hearty iron]

is there anything you did to speed up the process? so I can just get it the rest of the way there

[hoary cedar]

Nothing drastic I just played with them

[hearty iron]

might be device lottery then, I've fumbled with mine a bit

they are a lot less stiff but I'm having issues actually triggering the membranes underneath

quite a few missed inputs there

[quick ravine]

Actually a better offer is coming up for the g350 (stock might be limited) Add cuppons to it and it might go below 30. (Check the upcoming price)

[hearty iron]

oooo that's not bad at all, although I don't really want another rk3326 device unless it goes super low just because I already have two of them

[final saffron]

I have a r36s that I broke the display ribbon latch on doing a simple button swap. Hoping reusing the r36s membranes help the u8.

I've taken quite a few consumer electronics apart in my life, but I was not at all prepared for the fragility and low quality of an r36s. I'll be extra careful cracking open the u8

[hearty iron]

I definitely would be, since I always heard that the r36s has solid build quality. I remember I took apart an x7 a while back and it was the worst thing I've taken apart easily

I never could get the shoulder buttons back in properly afterwards bc they were held in with small pieces of plastic

but I hope that the r36s is a huge step above an x7 in build quality like it is in every other way

and I hope that the u8's experience in disassembly goes well, definitely update us here. it feels pretty solid in the hand so I imagine it will

[hearty iron]

in case anyone wants to pick one up, it's well worth it imo esp for this price

[hollow echo]

Hi, I heared the recent RK3326 does use the 1.5Ghz in PSP emulating, but Our copy machines (Like K36s, U8, RX6H) only use stock clock(1.3Ghz),
So have lower frame in psp. Is there any method to change clocks like original ArkOS?

[hoary cedar]

I don’t think there is but you could try ppsspp-standalone2021

So it’s using RK3326T?

[balmy wind]

Just to confirm, I received the console today and it's legit. Wow

I thought could be a scam but it's real

[final saffron]

You win the aliexpress game. Congratulations

[deep tundra]

ok, gb300 level pricing, thats a win

[grizzled cairn]

Mine is on the way. I cant waiting the disassemble it 😄

[hearty iron]

that is an insane deal, good shit man :)

[hearty iron]

yeah pretty much, it's insane

I paid a whole 32 for mine but ngl I am not upset with the price I paid either, I just wish I waited like a week or two, 32 was just a lowpoint in the pricing at the time so I grabbed it

[balmy wind]

With arkos installed the right stick is inverted vertical and horizontal, someone know how to solve this?

[junior bear]

Remap in emulator individually

[balmy wind]

Yeah but with drastic doesn't work

After remaping correctly the stylus controller doesn't move at all

[final saffron]

@hoary cedar Hey, I'm working on a super weird bug with the mouse on rotated-screen devices. When you fix the screen on the U8 do you include stuff that remaps mouse directionality too?

[hoary cedar]

Iirc, that was in the sdl patch as well.

[final saffron]

oh were you using patchsdl?

er hacksdl?

https://github.com/cdeletre/hacksdl

The reason I ask is I'm implementing code in portmaster that emulates touchscreen operations, aka an absolute mouse, and it's not rotated on U8 and Odroid Go Ultra but regular mouse input (like if you connect a usb mouse) is and I'm wondering how the rotation is done in the first place.

or was it done in a udev hwdb transformation matrix

[hoary cedar]

You can find sdl for ArkOS here and it’s patches https://github.com/christianhaitian/rk3326_core_builds/blob/rk3326/patches/sdl2-patch-0004-odroidgoa-kmsdrm.patch

[hoary cedar]

Linked is the actual rotation patch, there’s also a cursor rotation patch in there I think patch #5

[final saffron]

Appreciate the info. Thanks.

Updates on the buttons for the U8, after some playtime (not even that much, I have yet to charge it, it arrived here at 73% and is still at around 50 and I've played with it for at least a couple hours now I wanna say) and the buttons feel a LOT better. The main issue I am noticing is missed inputs now, and I feel like it might be a software issue just because it's much MUCH worse on drastic (nsmb) than it is on snes9x (smw) for example, I could be wrong though. Any ideas on how to fix this? Or should I just do a membrane swap with one of my handhelds that are coming in?

I don't even know if a K36 or R36 Pro membrane will fit in the U8 but I don't know if anyone else has done it, as the r36s is the most popular for membrane swaps and I don't have one

Oddworld portmaster bug

[quick ravine]

So has anyone got a screen protrctor for it?? What is the rigjt size. I comparwd it to the new r40s (which I will soon return) and it feel like the r40s has a screen with a bit more height. Bezels are greater to.

Here is the cokparison of the screen protevtors they camw with

[junior bear]

odd bug

[quick ravine]

My guess is that it has something to do with how it manages the electrical signals. All this is just a guess, but for some reason the electric signal is sometimes weak and it doesnt get recognized by the receptor under the button. That is why a user who added aluminium foil under them solved thr issue, because he increased the conductitity so the signal would get recognized even if weak. I will try adding conductibe adhesives soon, to see if it fixes it. But I have detected this issue in the k36, rx6h and U8, with emuelec and arkos. Therefore I am not sure if it really is the components that lack sensitivity or something in the dtb/kenerl/whatever that causes the electrical signal to drop in power. But it is just a guess

[hearty iron]

nice game choice

[hearty iron]

also yeah I was gonna say, it comes with one

but if you want another, I am not quite sure, it says 4 inch display on the listings so I'd say try one of those and make sureit's not 4.3, as that's a common screen size too and is too big

[hearty iron]

huh, that is definitely interesting, I wonder how they positioned the aluminum foil to get it to work, as I have that onhand and could do that rather easily I imagine

I do think that could deffo be a possible issue tho, it would make sense, although I wonder why it depends on system to system, as it's been SO much worse on drastic than on snes9x for example

and even more evidence towards your idea is that it has repeating signals from my experience too, particularly on the dpad

definitely keep me up to date about this if you can and dm me if you have any more info, as if it's not too hard to do, I might do a fix of some sort with my own u8 since I think the buttons are the only thing holding this back from being a budget mini tsp

[quick ravine]

This is what the user said in the k36 chat

I will try this

[hearty iron]

ooo okay, tell me how that works

[hearty iron]

what is a blue tack btw? I imagine I could use glue or something to keep the foil in place but idk what type of glue would work best and is conductive

but that's good to know, thank you for finding that for me :)

I may very well try that

[junior bear]

blue tack is sticky rubber like substance. its like chewing gum but not as sticky. it is tacky but reusable.

[hoary cedar]

didnt know the r40s is also a 4 inch screen, well that’s probably why the naming is like that

[hoary cedar]

interesting so we might be able to add sensitivity to the dtb files, I’m not able to test it though

problem with blutack is it hardens over time when not being moved, since it’s a button it gets moved regularly but would probably get hard when not used for a long period of time

[hearty iron]

hmmm I will try it once I can get some, although I have never used it and have no idea how much to use

[hearty iron]

ahhhh yeah I might not go for that then, that's good to know as well

do you have any ideas on what could be used instead?

I am thinking of some type of electrically conductive adhesive, but I fear that'll make the buttons FAR worse to press

[hearty iron]

I could potentially! I have a U8 and a k36 coming, I'd rather test it on the k36 tho as I am more preferential of the U8

but once it gets here, if you want, you can send me files and I test them out

[junior bear]

better use double side tape

[hearty iron]

not a bad idea, might do that as well

[balmy wind]

This is only me? Anyone noticed It?

[junior bear]

known bug

[balmy wind]

:( hope the os is updated soon

[balmy wind]

How can I change the global hotkeys?

[quick ravine]

My computer is busted and I havent been able to flash any SDs in the las couple of weeks. But it might get fixed next week. Then I could test on k36, rx6h, u8 and possibly r36 pro if an improved dtb is available.

I'm also guessing you will be busy trying arkos on the r36 mini... I will wait for review on that one. Specially after the bad taste the r40s left

[wispy patio]

Talk me out of buying a U8.

[final saffron]

Do you like GBA?

Basically the only thing its good for is GBA. GBA on 640x480 is trash. But GBA on trimui smart pro is heavenly. Also theres a very high likelihood you'll need to open up your u8 to fiddle with the pieces to make controls not suck.

[silent dew]

Doesn't the U8 have a 800x480 resolution, or am I missing something?

[deep tundra]

it does

thats why he said its good for gba

[silent dew]

My bad, I get it now. He was referring to scaling.

I'll be receiving the U8 on monday since I got it on Ali for 9€. I only ordered it because of the price. I'll probably sell it since I’ve also ordered the V10 as my dedicated GBA device.

[final saffron]

Yeah I like the larger screen and 3x integer with better shader support over the v10

[silent dew]

I totally get it, but I feel like the GBA just doesn’t look right to me on screens larger than 3.5''. Also, my OCD can't stand black borders. I tried it on my RG556, and the look just didn’t sit right with me.

The V10 seems like the perfect device for what I want.

[final saffron]

Yeah ive never used one but GBA is so sensitive to scaling I think it'll look really good on v10

640x480 at 2.6x scale is just bad

[hearty iron]

buttons have too many issues, I enjoy mine but I also enjoy tinkering. If you want something that works out of the box, not worth it off of that alone

buttons came on the stiffer side and there are serious issues with missed inputs

[hearty iron]

I hope someone who is less financially stiff can test out the hardmods for fixing the u8 controls so I can see how it improves and what the best option is

since if I can improve the missed input problem, I would love this thing, but a lot of games are near or fully unplayable bc of it

[final saffron]

I've been unable to find cheap aftermarket membranes unfortunately. I luckily have a set of r36s ones from a device I destroyed by tinkering, but I'm not sure what could be done without them.

Since hall sticks cost like $3 you think you could find good membranes for $1.50 and have an amazing device with a little effort, but...

[final saffron]

Chatgpt suggested painting this on the carbon of the rubber membrane...

Conductive Ink Pen
https://a.aliexpress.com/_mNx8nUL

[junior bear]

or you could try copper foil tape.

[hearty iron]

I will deffo give both a go

I just dont wanna damage the console and I'm really afraid of doing so

[carmine sierra]

These were my findings weeks ago. Worst out of the box experience I've had in a long time... Litteraly unplaybale. Seems like a quickly and shoddily slapped together handheld IMHO. I ended up returning both units. Happy I did! Could not bring it upon myself to sell this piece of e-waste to some unknowing poor soul. Any SF2000 or GB300 will run laps around the U8 in terms of usability and playability.

[carmine sierra]

Just to be clear.. I wouldn't call any handheld e-waste just like that!
But in this case, well. Most non-technically inclined people will simply toss this thing after finding out their favorite game is unplayable. At least the RX6H/K36S/M17 and the likes can be played out of the box with much less issues. The U8 on the other hand is an actual case of e-waste..

[hearty iron]

I am one to try and redeem handhelds, I do agree it's pretty bad out of the box, but I'd argue something like an m17 with it's really bad stock fw is worse, plus it's significantly less powerful than the u8 too

but you're right, the games are playable, just very stretched and n64 is shoddy

meanwhile mario 64 was honestly super good on the u8

idk why

ima do the hard mods at some point and post my findings

[carmine sierra]

I am speaking purely from a usability perspective. Most people purchasing these handhelds are "average joe's" at the end of the day. Not everyone is an enthusiast and feels a need to redeem handhelds. Most people just want to buy something and just use and enjoy it without the need for tinkering. Those people will end up tossing this thing. I would argue this makes it a failed product.

There is no need to argue the M17's power or FW, since the M17 can be played out of the box without any missing inputs. This makes the M17 an infinite better product off the shelf, even with all it's flaws! Yes the U8 has a lot of potential, but since it's most basic hardware functionality (button inputs) is severely flawed.. It's useless to most people as is. Even if they somehow hypothetically cramped a T820 with an HD+ AMOLED screen under the hood... It wouldn't matter, since I can't properly play a game due to something as simple as the buttons!

[hearty iron]

Eh, agree to disagree

Plus I'm more worried about getting the most out of this thing that I can

and I have like no experience with hardmodding so I am super worried about it not working and/or damaging the console but I think I'd take that risk if it significantly improves usability

[hearty iron]

I don't normally fully trust chatgpt but this is cheap and I see a LOT of posts on reddit about this solution so I may try it

[hearty iron]

should I buy the copper one or silver? I think the silver would be better but idk

[carmine sierra]

All good, I feel like we are having two different conversations anyway lol. Enjoy tinkering with your U8! I'm curiously watching from the sidelines.

[balmy wind]

U8 at 16€ if anyone wants it
https://a.aliexpress.com/_Evt1JAo

[hearty iron]

mannn why all these prices show up after I already bought mine 😭

[hearty iron]

thank you, wish me luck bc I deffo need it, I gotta wait until I come up on some more money tho and then ima try to buy that silver conductive ink

maybe I'll get lucky and the controls will fix themselves (every time I have played so far, it's been a better experience than the last)

bc the controls aren't all that stiff anymore, just inputs get missed

esp in heavier emulators like drastic

so hopefully the ink will help, in the meantime I might try the aluminum foil strategy if I can find some thin double sided tape

I just am afraid using the tape won't be good for strengthening the electrical signal and that it'll negate the effectiveness of the foil

[balmy wind]

The screws of this machine are very stiff

This thing is impossible to open

[hollow echo]

I guess it would be other screw driver. PH/PZ difference?

[solemn tapir]

[balmy wind]

Yeah mine are destroyed

[hollow echo]

If you are using pz driver, then use ph. if offside, then use pz. Using correct driver could save the world
Also almost broken screws

[lost sky]

Just got in my U8. I feel like the travel on the buttons is too much, and it often doesn’t actuate the button. Especially on the far right face button ‘a’.
It’s leading to a lot of missed inputs. Is anyone else experiencing the same issue with their units?

[final saffron]

Yeah scroll up, it's a big topic of discussion and frustratrion.

[hearty iron]

what is the difference between the two?

[hearty iron]

yeah, big time

the travel is a LOT, we think it's conducting the signal poorly leading to the missed inputs bc I feel like I am deffo pushing the buttons still

[final saffron]

Phillips heads are designed to strip before they snap the screw. Pozidrive heads will not cam out and are superior when driven into soft material. There's a rough classification that USA prefers phillips and EU prefers pozidrive, but it's not universal.

[hearty iron]

huh, interesting! I never knew those two were different, I don't think I have any pozi but I have normally managed to unscrew most things without stripping the screws

but I imagine that if it got stripped that bad, those screws are just made of paper

not literally paper but yk

so I am a bit afraid to open mine now

[final saffron]

The drivers are mostly interchangeable. You'll find pozidrive on most Ikea furniture assemblies.

[hearty iron]

I have never been to an ikea but I deffo want to

[balmy wind]

Any tip for unscrew damaged screws? My U8 screws are fucked

[final saffron]

https://www.aliexpress.us/item/3256805212409610.html

I mean, it's always annoying to buy tools that are more expensive than the thing they're repairing

[final saffron]

If they're not entirely fucked you might try heating them up with a soldering iron to release them from the plastic

If you don't have a soldering iron, heating your screwdriver up really hot on the stove will work well enough... then hold it on the screw for a while to get it to start melting the plastic, then unscrew

[sudden cargo]

Buy it. It’s great. For $30 it’s a steal. 🙂

[carmine sierra]

Just read the comments about the missing button inputs very well before you pull the trigger. There are less troublesome handhelds with identical performance available at the exact same pricepoint. Ofcourse, this is just my own personal opinion!

[wispy patio]

Thanks everyone.

[hearty iron]

of course :) if you wanna tinker then go for it, if not then keep looking imo

[hearty iron]

if only they got the buttons right, then this would be the best handheld at the price point bc even the stock fw is really good imo 😔

[solemn tapir]

@hoary cedar What kind of Wi-Fi Chipset does work with R36s clone's ArkOS? RTL8811 could work?

[hearty iron]

wait, so it was the membranes and not the poor connection? am I understanding this right?

or is it the pads that are the issue?

[solemn tapir]

The D-pad button is not smooth yet, but when playing Rockman, you can charge and jump better.

I am not good at English 🤣

It's okay but not very good.

[quick ravine]

But is that regarding the "feeling" if the dpad or regarding the buton misdetections?

In case you have linux, this is what ClaudeAi suggests

[quick ravine]

Wooww, that is amazing. As soon as I get my pc back I'm tryint it. Could you also edit the k36 dtb (it think it will be easier to test since the u8 has buttons that requiere pressing hard). Also out of curiosity, what was the poll interval difference with the r36s??

[hollow echo]

So what have to do?
Use the img in @hoary cedar 's github(for U8) and change the dtb too?
Still I not got my U8, So what can I do now is just looking for info...

[lost sky]

Ping me if there are other improvements to pin

[hoary cedar]

I'm trying with u8 first so we can pinpoint if it's really software or hardware. The r36s has it set as 10ms while the k36 has it set to 30ms

Here's a dtb file I'm testing if any of you guys would like to try as well. I changed the poll interval to match what the r36s has.

[hoary cedar]

@lost sky pin this one instead xD

[quick ravine]

Thanks for trying man. It would be great if you could finally solve the persitent button misdetection issue

[hollow echo]

I heared that Using the R36s' D-pad rubber would help U8

[hoary cedar]

Here's another one with the same poll rate and debounce reduced to 50ms from 100ms

[carmine sierra]

@hoary cedar to the rescue as usual!

[lost sky]

Let me know when someone can test and confirm if it helps

[hollow echo]

So, How could test it...? is there any way to know it by regularly?

[hoary cedar]

im interested on the inputs of those that changed their membranes I'm running mine on the stock membrane but it's already broken in so it's easier to press them (I think)

[wet cave]

Hi guys. I bought a r36s clone. Now i'm trying to switch from my stock SD to another one. I tried to clone my SD, but didnt work it. i'm kinda newbie and i dont know where can i find the right image to adjust my new SD card. Here's my original dtb file:

[hearty iron]

what is this replying to? I am confused

[hearty iron]

I am also running stock membrane, I am still running the stock os and don't have a spare sd card to install arkos yet so for now I am afraid I am not much help, I hope someone is able to test the files and come to a conclusion

I could copy the files over from the stock but in windows, the stock os has a bunch of partitions that windows cant detect and I don't wanna lose any potential backup of the stock fw just in case

[hearty iron]

update: found some spare sd cards, I need to install arkos still so later on today I'll do that and then post my findings in here. I have a question though, if I install ark, can I still use the stock os if I just swap the sd cards?

[hoary cedar]

https://tenor.com/view/definitely-maybe-romance-comedy-ryan-reynolds-yep-gif-5008341450946414225

[quick ravine]

To a message that was edited and moved below (basically the first message of aeolusux saying he had edited the dtb to match the r36s)

[balmy wind]

This is my way to use It. One sd with arkos for ports and scummvm and stock sd for everything else

[hearty iron]

thank you :)

[hearty iron]

ooo okay, thank you for clearing it up :)

[hearty iron]

what is scummvm? I've never heard of that before

I really like the stock os for the u8 honestly just bc it has all the emulator settings unlocked right there AND has some absolutely fire music on the selection screen

but ye, I'll do that later today then :)

[balmy wind]

It's an emulator for point and click games like monkey island, sam and max...

[hearty iron]

ooooo okay, that's cool! I didn't know those had a way to be emulated, especially without a touchscreen! :o

[balmy wind]

I love those games and they only work on ArkOs

[hearty iron]

arkos is great

[hearty iron]

I didn't know who to ask so sorry for the ping if you're unsure, but where do I put the dtb file?

[quick ravine]

Are we talking arkos or emuelec? In emuelec it's on the emuelec partition, and in arkos in the main partiton that has the boot file (I dont remember what it's named, not the easyroms).

[hearty iron]

wait, the dtb file would work on emuelec too? damn I didn't need to setup arkos for it then lol

but yeah, I got arkos on another card now just to test this, it wont be my permanent arkos card though as I want to have a larger one for that and this one is only 32gb as it's what I had on hand

thank you :) I will test this shortly

[quick ravine]

No, if you reffer to the one uploaded by aeolus then it's for arkos. It might work on emuelec but better test on arkos.

[hearty iron]

ah, okay, that's good to know then :) I already have arkos set up so I'll just use it there

[hearty iron]

gonna do some extended testing on mario world of both just to see how the file changes things

[wet cave]

anyone?

[junior bear]

wrong channel
#1274131112351764532 message

[hearty iron]

upon testing of this file, unfortunately there was no meaningful difference when it comes to missed inputs, the ultimate culprit could possibly be just too much travel for the buttons to be activated, and if that is the case, I'm not sure what could fix that

it could be that I put the file into the wrong location or my choice of game (Super Mario World) wasn't the best one to test it with, but I had a lot of missed jumps still

I placed the file into the root of the main partition (not the roms one, can't remember the exact name) since there was already a file there of the same name, just with an older date

[wet cave]

Thankssss!!

[quick ravine]

Not sure about the dtb thing, cant check cause I dont have my pc. The U8 letter buttons have issues of their own beyond the signal issue. Did you notice any dpad input misdetections?

[hearty iron]

Yes I did, not since changing the file but I can try testing it more later. I know that originally it had repeating inputs more than missed ones, but it had occasional misses too, just not nearly as bad as the buttons

[final saffron]

repeats would be fixed by longer debounce

[final saffron]

Got my U8 finally... def gonna heat the screws up before trying to extract them. I see what everyone means by the large play on the buttons/dpad but I think a lot of it is software too. I had a missed dpad press that would not correct while I held the dpad down which doesn't seem like a conductivity issue to me.

[quick ravine]

The issue still occurs in arkos. You can try the dtb they shared with the ongoing fixes

It should be pinned

[hearty iron]

How do you suggest heating them? I am afraid of melting the plastic

[final saffron]

Probably just gonna hit the screwdriver with a blowtorch, but this is all theoretical. Melting the plastic somewhat is the goal. I had to leave town for a few days though so I can't try right away.

[hearty iron]

ah, okay, I hope that you have fun on your trip :)

[hoary cedar]

I was given screws from the factory when I was sent the r50s so I replaced screws on my u8 once I learned they get stripped

and yeah one of my screws got stripped so I used a bigger bit to get it out

[hearty iron]

I am deeply afraid but ima deffo try to open it up at some point, surely there has to be SOMETHING we can do that's a consistent solution to this

it has SOOO much potential I'll sob if this thing can't be fixed to be good

[final saffron]

I got all 4 screws out unstripped. Heated a #1 Phillips over the stove for 60s. Held it to the screw for 15s until I could smell melting plastic. Was very careful about not stripping them even still.

[hearty iron]

oooo that's good progress, thank you for letting me kno, I might try similarly but I'd have to use a match or a lighter, since my stove isn't open fire like that. Those are actually illegal where I live lol

[balmy wind]

Really? I didn't know were illegal on some countries. I managed to open mine using that same method and replaced the screws with better ones

[hollow echo]

Wow... fire stove is illegal in some country...? really interesting

[final saffron]

Above pic is a camping stove.
Here's the r36s membranes versus U8 membrane. Note the smaller pads for the u8 membranes.

[junior bear]

why so tiny

[hoary cedar]

Not just countries, some houses when you rent they don’t allow open flame. Units when I lived in sydney only has hot plate or induction.

[final saffron]

U8 (top) versus r36s (bottom) strangely the u8 button housing has the notches for the tabs but the buttons dont have the tabs.

Oh wait no it doesn't. Hrmmm... I think I might fill the void with epoxy in these buttons.

[hoary cedar]

what happened to y

[hearty iron]

it's not illegal in the entire US, but my specific area that I live in it is because we are heavily forested and we sometimes (not in recent years though) used to go close to a month without rain, the ground would get cracks in it sometimes, it was crazy

[hearty iron]

huh, this is indeed interesting

do you have any ideas on the input issues yet?

unless the smaller contacts could be the issue

[final saffron]

I think thats why

[quick ravine]

I actually just added bigger contacts to the g28, which also has misdetections, and so far the issue persists. I even tried a wider size than the one on the pic.

[hearty iron]

well, that's unfortunately not a fix it seems

why must random companies ruin their otherwise good handhelds 😭

[quick ravine]

Yeah, but I guess at the end it is a double edge sword. Since all these emuelec 4.7 consoles are clones of clones it means some of the original errors are carried over again and again. The "good" thing though, is that since there are more consoles with the same issue, the matter gets more attention, and if a solution is found, it can apply to previous clones. If the k36 was the only one with the issue, it probably would have never gotten the attention it seems to have now. I have been looking for a solution for the k36 misdetections since september xD. And many people still dont even notice the issue... usually most reviews dont even mention it, and it should be a primary focus with any EE 4.7 clone.

[hearty iron]

It's crazy bc I have watched k36 reviews too and never heard about this issue

but I've experience it firsthand

it's not often enough to be confident in is the reason I think ppl dont notice. Like it happens rather occasional with the ee4.7 devices. I only noticed it on the U8 bc it was rather common

[carmine sierra]

Because random companies make random decisions based on costs alone. Leading to random outcomes (and sometimes failed products). There is no real thinking/development process involved with most of these new companies. That's what's happening in the rk3266/rk3128 handheld sphere now. They have run out of RG35XX/R36S/M17 templates and clone ideas so they're just releasing whatever (cheaper) iteration/modification of the same console they can think up at this point. That's how we get all these recent "U8's/RX6H's/R36MAX's/R36PRO's/K36S's/XF43's/G28's" and their likes. It's like throwing old things at the wall under a different angle, and seeing what sticks this time.. Sometimes it works out, most times it won't. The ONLY noteworthy recently released rk3266 handheld I can think of would be: BatleXP G350. Here a company did invest in some development and ACTUALLY IMPROVED upon the original concept for once. Justifying it's slightly higher price in that way. Most other new rk3266/rk3128 handhelds are just "We got RG35XX/R36S/M17 at home" at this point. None of them is as good as the original, yet most of them are priced roughly the same. 😦

[solemn tapir]

How to analog right setting

[hearty iron]

Unfortunately it seems like it, you're right on the money but I just wish they'd put in a smidgen of effort, hell even if the put the effort they put into the packaging into the handheld I'd be fine. The U8 has the best firmware of any 3326 device I've owned (besides maybe the v90 which came with arkos out of the box) and is all around really good software wise. I just hope that through the ppl in this server we can figure out a way to salvage it

I have hope that it can be potentially good

[quick ravine]

Agree and disagree. Yeah, most of the decisions are based on cost alone, but most of them try some kind on wanky thing to make it differet. The k36 had a gripable ass, the u8 has a wide screen, the rx6h has very comfortable grips and weird lights, the r36 max is a vertical rk3326 with a 1:1 screen, the r36 mini has a central single stick and the g28 is the better version of the m17. Want it or not, these clones bring some innovation and variety. If it werent because all of the mentioned ones have button misdetections, they would be very recomendable for their price.
The g350 is just one more of them that uses a moded emuelec than doesnt have the misdetection issues, and the only "new thing" is rumble. And you wont find many XX series handhelds below 40 bucks.
My point is that there is a market for these clones, and 3 years from now the rk3326 will still rock, becsuse it can play up to ps1 flawlessly. Back in 2017, when I got a raspberry pi and installed RetroPie, it became a dream of mine to someday have a handhelds that could run Retropie. And now every month we get new models of handhelds that are protable retropies for less than 40 bucks.
I just wish they fixed the button misdetection issue.

[lost sky]

Is there a place to redownload the stock firmware?

[hearty iron]

for U8? I don't know, I do have a backup of it tho if you want (I have not tested if it works tho)

[solemn tapir]

in pin

[solemn tapir]

stock

[hearty iron]

you took the words out of my mouth. even with the issues, the fact that we can get ps1 capable handdhelds for such a cheap price nowadays is insane. For this same price point 10 years ago, we were still getting famiclones or a REALLY crappy emulation powered genesis clone.

It's truly remarkable how far emulation and hardware has come down. Young me is astonished with modern emulation capabilities

I'm just glad we're past the days of famiclones for the most part. Yeah they're still listed but it's for dirt cheap and it's not as bad as some of them used to be not too long ago

I mean, ultimately (at least here in the US) a real restaurant meal is gonna cost more than most of the rk3326 handhelds do, esp those on the lower end

I agree with your and the points of the other guy a lot. Even if a lot of decisions are intended to cost cut, it's not like most of these are really bad, they are often just mediocre at the worst or just one major flaw

[solemn tapir]

Why stock fw right analog has no issues

[quick ravine]

I think it's because of the emuelec kernel

[hoary cedar]

Whats the issue on the right analog on the u8?

[quick ravine]

My bad, I got confused and though it was about the rx6h. (I still havnt havnt been able to try the latest builds or the u8 moded dtb timings). Not sure what he was refering to, maybe it was about drastic?

[solemn tapir]

I found that it all showed the opposite.

Right show left

[hearty iron]

ooo where the inputs are reversed? someone mentioned that on the k36 as well I believe, I think it's another issue amongst multiple of them, I've just never noticed it as I haven't tried anything that needed 2 sticks yet

[grizzled cairn]

Did anbody try this device boot AmberElec ?

[balmy wind]

Right analog is inverted on arkos

[hoary cedar]

Well that’s weird what emulator is this? or is it ports? only ports and probably ps1 can use the right sticks iirc

[balmy wind]

It's on all the console, menus, emulators, it's a bug that affects all the system with ArkOs

It's annoying on ports and drastic

[hoary cedar]

All console don't use the right sticks though

[balmy wind]

You can use right stick to navigate emulationstation. It's one of the ways I managed to see this bug

[hoary cedar]

Aight that means it's probably from the dtb

[balmy wind]

I don't use ArkOs as main system because this bug and because audio also has a bug where it mutes and unmutes randomly when headphones plugged

[mild sorrel]

I have similar issues with dpad control. I tried the news dtb, but, sometimes, when i pulse a direction and release, the console continues to display the same direction and does not change until I release the dpad and select another direction. The issue is also repeated with the triggers, when I leave them pressed and release them, sometimes it continues marking as if they are pressed.

These issues occurs in my u8 with Arkos and Emuelec

[hoary cedar]

You have bad joysticks

[solemn tapir]

I found in emulator ps1 nds
Portmaster I think it's a bug in arkos

[hearty iron]

I haven't had that issue with the triggers, but I have with the dpad, it's a lot less common than the missed inputs (especially on the buttons) but it's happened before

it has also happened on my r36 pro so I believe it's a software issue, hoping we can find a fix to the missed inputs soon 🙏

[junior bear]

same, but i don't think it is arkos bug tho.

[balmy wind]

This file is easy to modify? I would like to try to solve this myself

[hoary cedar]

Should be, you can decompile the dtb and invert the values on play_joystick right x and right y

I was gonna do it earlier but something came up

[balmy wind]

Okay I'm gonna do it. Any idea how to solve the headphones bug?

[balmy wind]

Inverted the values but the right joystick is still inverted

[hearty iron]

hmmm that's interesting

How too port firmware EmuELEC-R36SClone.aarch64-4.8-TEST-04212024-chi.img.gz - updated RetroArch cores - working internet connection via ethernet adapter - Portmaster working to U8

[sudden cargo]

The QC on the buttons is bad some have reported worse, for me the A face button and the down dpad inputs don't work sometimes, I get missed inputs. 🙁

[hearty iron]

That's been consistent with U8 owners here to my knowledge. I get missed inputs very often but also the firmware on the u8 is used in multiple devices (k36, r36 pro/max) and the firmware is also causing missed inputs, so it's just really rough as a U8 owner rn. I'm hoping someone can come out with a possible/partial fix for it

[vale bay]

system is EE4.7 or arkos??

[hearty iron]

it's present on both

[quick ravine]

Ok, so for anyone who wants to try at their own risk, I found a membrain that kind of does the job. I had it in a box, so I could be mistaken about it's origin, but it was all balck and cutted manually by me with a t-shape, so I am almost sure it belonged to a gb300, which is actually very cheap. I only tried it for the letter buttons, and although they arent perfect, I preffer it much more than the OG. That said, since the buttons are connected, when you press Y to run in SMW and at the same time you press B to jump, B feels a bit to soft. However, I still think I fixes misinputs caused by hardware (the usual EE buton misdetectiions are still there). Before the change, the B button was the one with most failed recongnitions, but since the change I have noticed B failing just as much as with Y. Now that I have "fixed" misdetections because of the bad membrains, I plan to download the latest arkos u8 version and try the dtb aeolusux moded. I probably wont have time until the weekend, but I will let you whataver the results are.

[hearty iron]

could I possibly get an image of what you mean by t shape membranes? as I have quite a few gb300s and I wouldn't mind potentially swapping a membrane out for my u8 since I value my u8 a lot more

that's great news potentially, I am willing to give it a try

[quick ravine]

I cant show you because it's inside. But what I mean is that the gb300 has a large one piece membraine, so a few months ago I had tu cut it to try to fit it in a different console. I had cut it with the shape of the depad, so it would fit into place. I will show you a pic of a diferrnt mrmbraine that I had cut the same way

I think that is for an snes controller.

You probably dont need to cut it so thin. Just make sure there arent any borders that cause it to not fit correctly.

It is still not perfect, but I like it much more than the OG feelings. I'm also thinking about cutting the connected buttons, but I will wait until I have done some more testing.

You can probably also susbstitute the dpad. The constrast between the hard dpad and new soft buttons can be very noticeable.

[balmy wind]

Accidentally I broke the connection of the A button and now it rotates. The interesting thing is that it works much better know

[hearty iron]

define substitute, like using another membrane?

[hearty iron]

PFFF that's hilarious that it improved

[hearty iron]

thank you so much, thank you :) I am likely gonna experiment with the face buttons first as those are the ones that gave me issues more than the dpad (although I had issues with both)

I gotta figure out which gb300 is gonna get savagely ripped apart first though lol

[quick ravine]

Yeah, sorry for not expressing it right. I mean to also switch the dpad membraine.

[hearty iron]

you're all good :)

I have an older gb300 with clicky dpad (I will die on the hill that they had a minor hardware refresh) that I could use BUT I am afraid to bc I have a lot of accidental detections on that specific gb300 with pressing down, it thinks I'm pressing down often times when pressing left or right

but it has a nice click to it otherwise

but idm a softer feel, I like and prefer a clicky one but I'll take what I can get if it means my u8 works better lol

I'll try a swap at some point in the future

[quick ravine]

I channged the membrain in the purple. The original membraine is so stiff it even hides that the buttons are connected.

[quick ravine]

I dont think the issue here is the contacr pads. It's more the lack of "mushiness" of the membrain

[hearty iron]

the purple model is the best color imo

I'm sure the u8 has a rattle now post membrance switch which sucks but it's fine, will take that for better buttons

[hearty iron]

yeah, it's very possible, you need mushy membranes too with that much travel

I won't do the switch rn but I will do it in the near future and report back

might be a couple days bc I have so much going on this week lol

but might even be later today, depends if I feel motivated enough to mess with it, I've been enjoying a break from tweaking handhelds all the time (tweaking my gb300 models were endless)

[quick ravine]

The worst part for me always is re-conecting the sticks and the screen to the main board. I once broke a conector and now I have panic to them. So yeah, do it when you have some time to do it without hurries.

[hearty iron]

wait I have to disconnect the sticks to replace the membranes?

I am gonna try to avoid doing the screen bc so far I am 0-3 with ribbon cables

wait no

1-3

still pretty bad

ribbon cables ruin my life

[final saffron]

Thats how I got my r36s membranes. I broke the screen latch off trying to reconnect

[quick ravine]

At least with these buget consoles qhen you "brake" them it doesnt hurt as much as when it happens with a +70 console. But it still feels very bad

[final saffron]

I've worked on a lot of electronics before but I was in no way prepared for the low quality of the r36s. I'm amazed they can assemble them so effectively.

[quick ravine]

Aghh. I just found the GB300 buttons. They have a swastica style conection and seem to have the same size. The probably feel better when pressing 2 at the same time. I dont want to open it again...

[final saffron]

those won't work. U8 buttons only have room for one tab exiting the button housing

note the secondary tabs on those buttons. That's how the r36s does it but r36s buttons don't fit on the u8

#1342220912057127066 message

[quick ravine]

Hmmm, I see. I though the housing didnt matter that much though. A user said that he accidentally broke the conection and now his button rotates.

[balmy wind]

Yeah button rotates but the detections are soo much better

[final saffron]

Yeah you could always snip the little tabs or connectors. Also maybe filling the + void on the back of the button with glue will depress the membrane more.

I'm using a solid 3d printed dpad and it works much better.

[hearty iron]

yeah true, that is very true

I am less worried about breaking my gb300 for that reason than my u8, but also breaking the u8 wont be the worst in the world

[quick ravine]

Hey. So I swapped the letter button membrain with the membraine from the gb300 (re-cutted) and the buttons are much more responsive. I then treid the dtb that you uplaoded with the moded poll rate and debounce, and after playing for 30 minutes it seems to have improved the misdetections, but I still get some misinputs (though I would say with less frequency). I might also end up swaping the dpad membraine as well cause I still think some of the misdetections are caused by the membraine. The issue is still there however becasue on 3 occasions I would be holding B but mario would not run). (3 times in 30 minutes is much better than what I had before). I will do more testing on the weekend. Also, is there any other input sensititvy parameter in the dtb that is far of from what is set for the r36s?

[hoary cedar]

Do you have a k36? those have way better buttons than these so I might make a modified dtb for that to confirm

[hearty iron]

I dooooo, but I dunno how quickly I'll be able to test new files

[solemn tapir]

Will the right analog stick be fixed?

[quick ravine]

I have various K36 to test it.

[balmy wind]

I can confirm that snip the tabs between buttons make a huuuge difference. The buttons are surprisingly responsible

For me this is the fix to the button issue

[quick ravine]

Do your buttons rotate now??

[balmy wind]

Nope only the A button

Snipped the middle of the tabs so the don't rotate

[regal lion]

Hi everyone, yesterday for the first time a strange thing happened. While I was playing it turned off by itself, I turn it back on, play and again like this. The u8 turns on, you can play, after a certain amount of time it turns off by itself. I have 2 and on the other one I tried to insert the same memory card and I played smoothly longer than the time I expected for the crash. Do you know what's happening or if you have any suggestions on what to do in this case?

[regal lion]

Update: I opened it and as I moved the battery slightly it unsoldered. I'll try to re-solder everything and see what happens.

[hoary cedar]

Not anytime soon, We need a completely new kernel for that. Easiest thing to do is remap it. Not much games use it anyways.

[mild sorrel]

I think it's a software issue because it happens to me with the dpad, the a and b buttons (I haven't tried with x and y, but I think it will happen the same way) and with the triggers. With Emuelec 4.7 and Arkos of AeolusUX

[hearty iron]

I hope it works well

[hearty iron]

huh, interesting! could you show some visuals on how to snip them? that's a lot easier to do than swapping out the membranes I feel so I'd rather do that (plus I don't have to sacrifice my gb300 then)

[balmy wind]

What I've done is cut with scissors on the red marks

[hearty iron]

ohhh okay, I'll try that! thank you :)

[sudden cargo]

What’s the best OS to run on the U8 right now?

[hearty iron]

I quite enjoy the stock but arkos has support for portmaster and the like iirc

[balmy wind]

Arkos have issues and bugs on basic system features like sleep mode, jack audio and right joystick. It's a great OS but I must recommend stock one

[sudden cargo]

Currently using stock and it's working fine for me, was just wondering if anything was out yet.

[hearty iron]

this is good to know!

[hearty iron]

how have the buttons been for you?

[sudden cargo]

Only the buttons have been an issue but I’m just living with it. I think for $20 it’s a beast. The buttons are weird and I get missed inputs on A and on B some times but I think it’s getting better with use. They’re stiff and just need some wearing to be more usable. I don’t have the time to replace them or open this up.

[hearty iron]

That's completely fair, I can understand that. I think it varies some from console to console, mine are unusably bad, I can't consistently play mario on it bc of how often inputs are missed

it's why it's in my plans to try some fixes for it, I hope that they end up working out

[hoary cedar]

What’s wrong with sleep mode? 🤔

[balmy wind]

Only works one time, the second time you try to use sleep mode the console gets a black screen

[ancient ridge]

probably this issue

[balmy wind]

Yeah that's the issue

[hoary cedar]

Well shit we may need to use the 66hz config then

[quick ravine]

@hoary cedar hey so since the g350 runs EE 4.7 and it doesnt have input misdetecrions I though we could take some advantage of that. I somehow managed to extract the joypad info from the battlexp dtb and there is no debounce setting. Also the poll interval is 10ms. Would it make sense then to reduce the debounce and poll to 10ms?? (I am basically following AI instructions xD)

(Here are both to compare) (k36 vs g350)

[hoary cedar]

Well I guess but isn’t that this already? #1342220912057127066 message

[quick ravine]

Yeah but not the debounce. You lowered to 50ms, and since the option isnt present in the g350 i though it might make sense to reduce it to 10ms. Just exploring

[hoary cedar]

Nope this one is the one with adjusted debounce #1342220912057127066 message

Hang on I’ll make one for k36 i forgot to do so

[quick ravine]

Can you also try to make a version with the debounce at 10ms?

I tried myself, but i got some errors while converting, so I prefer to try a "good" version.

[hearty iron]

I can test the k36 one, technically I'll be testing it on the r36 pro but I imagine it's roughly the same

if anything, to my experience, the buttons are less stiff on an r36 pro (although not stiff really on the k36 either, just moreso)

[ancient ridge]

It seems that there is nothing left to try with dtb, guessing it depends on the joypad driver.

[quick ravine]

If the problem is the joypad driver, would switching to gpio-keys in the dtb fix the issue? (AI told me xD)

[hoary cedar]

I was sent the drivers for the U8, zed_joystick a.k.a. play_joystick

so Duri was on the right track that it's the zed_joystick from JELOS #1274131112351764532 message

[hoary cedar]

This also confirms that debounce can't be set dynamically as it's hardcoded to 10ms.

[hearty iron]

damnn, I hope that this information though helps us get closer to the missed inputs on these 4.7 devices, if the entirely new kernel doesn't fix it lol (it likely will)

[quick ravine]

"add by RuiShuo" Sounds familiar. Wasn't there a name like that in the wifi settings of one of the unlocked images?

[hoary cedar]

Yes

[quick ravine]

we should invite him to this discord

[hoary cedar]

he is

[quick ravine]

xD

can't find him with that name, might it be... xD

[junior bear]

[quick ravine]

I shared the zed_joystic driver with AI and this is whay it had to say:

"There's a timer used to enable GPIO interrupts with a hardcoded delay of 100ms , and the workqueue delay is also set to 10ms.

The 100ms timer delay in zed_joystick.c before enabling the GPIO interrupts is particularly concerning. It introduces a significant latency before button presses are even detected.

The 10ms workqueue delay might also contribute to missed presses, especially if the system is under heavy load."

[hearty iron]

hmmm I wonder how that would be fixed

although that would explain why I feel like there's an input delay in games

I was play nsmb on my r36 pro (using it as an example instead of my u8 bc it uses almost the same firmware and has less hardware button issues) and then swapped to my gb300 (playing super mario world) and I noticed how the presses on my gb300 felt instantaneous whilst the r36p felt slightly delayed

ideally I'd like to continue to use the stock fw as it's REALLY nice and fits what I need perfectly and then some in terms of settings, but I deffo am struggling with button presses

I also have noticed a significant amount of ghost presses on the dpad for said device, it's REALLY bad for a platforming game like mario lol, I'll let go of the dpad but it'll continue moving until I press the direction again, and then it'll stop, it's like joystick drift but on a dpad lol

[balmy wind]

Same for me. You nailed with drift on dpad It feels literally like that

[hearty iron]

it's so crazy, my Wii U gamepad has drift on it's left stick and it feels the exact same as this except this is much more often, I am unsure what the cause is but I am gonna point at the driver since to my knowledge, the membranes on this clone are quite good

dpad drift is never something I thought I'd experience but here we are lol, I hope it's able to be fixed since a lot of devs are working on rebuilding the kernel and I imagine that will include the drivers too

[hoary cedar]

The 100ms delay is on start of the device. The hardcoded debounce I already told. #1342220912057127066 message

[stray cypress]

Does anyone have the overlays used in u8? If so, could you please share them?

[quick ravine]

Ahh, thanks for clarifying.

[stray cypress]

I'm not very satisfied with the U8's screen.

[hearty iron]

that's likely just bad luck of the draw, idk how it is for others but my display was REALLY good, no bleed or anything

and it was bright and vibrant too

make sure there's no screen protector on if it's blurry

[stray cypress]

The viewing angle is particularly poor, especially when looking from the lower right to the upper left, resulting in significant color distortion.

[hearty iron]

huh, that's really strange, mine has an IPS display with no viewing angle issues to my knowledge, I'll try it out but I don't know why yours has that issue

wait wtf mine has it too

it's very much so minor, and it's at such an angle that I couldnt play any game realistically at that angle anyways

but that's definitely an issue

I still think yours is a worse case than mine but I do find it strange that this is an issue on a supposedly IPS display

it's either a terrible IPS or the best TN panel I've ever seen

[ancient ridge]

could you fix the analog sticks?

[stray cypress]

"What issues are you having with the analog sticks?"

[ancient ridge]

analog sticks don't work on U8 with Rocknix for MyMINI. Oh it looks you have a build for U8.

[stray cypress]

I haven't fully tested the U8 yet, so I'll need to wait a bit longer.

[hearty iron]

are you using the stock?

[vale bay]

https://github.com/gamely-code/retrohandle_U8

[hoary cedar]

You guys can use this on latest K36 build. @oblique void can you pin? 😁

[hoary cedar]

Thanks brother

[hearty iron]

oooo sick

what os?

[quick ravine]

Ok, so going back to the button misdetections issues, here is the x55's (rk3566 - emuelec 4.5) and u8's (rk3326 - emuelec 4.7) DTBs converted to .txt so you can compare them. I am also reuploading the zed_joystick driver for the u8 that aeolusUX got and the zed_joystick driver for the x55 from the github link that Duri found. The x55 doesnt have ocasional input misdetection issues, so maybe by comparing the DTBs and the drivers we can find a key differences that points to the cause of the ocasional misdetections. (I've tried running them through AI, but the content of the files is to large for them to evaluate correctly. All I got is that they might be using different drive force for the buttons (4mA or 6mA o 8mA), but I still dont really understand how dtb files work and can't verify it, so not sure about that)

[final saffron]

Lemme take a look

[final saffron]

Ok, just some stream of consciousness stuff as I compare the drivers...
First thing is that the x55 analog sticks use a circular deadzone while the u8 is just a square

Another thing, u8 driver disables interrupts for a moment, which could definitely contribute to missed inputs. x55 doesn't do this:
disable_irq_nosync(map[i].irq);//防止在probe相关数据结构没有初始化完成中断就进中断服务程序

reenabled here after 10ms

timer_setup(&zed_joystick_timer, enable_key_irq_timer_function, 0);
mod_timer(&zed_joystick_timer, jiffies + msecs_to_jiffies(10));

It's possible if you hit an ABXY button at the same time as a dpad these disabled interrupts, even if only for 10ms, would miss the dpad/button input

The u8 driver has some extra stuff to interpret analog stick as dpad which adds some obfuscation

Ok, so pumping the chinese comment through a translator it says:
// Prevent interrupts from entering the interrupt service routine before the probe-related data structures are completely initialized.

Oh wait, this is just during init

[quick ravine]

Have you been able to verify if both drivers have the 10ms hardcoded debounce. The AI said both have it, but human confirmation would be better.

[final saffron]

I see 100ms in the dtb you sent me

                debounce-interval = <0x64>;

0x64 hex is 100 decimal.

                if (jk->debounce_interval) 
                        ret = gpiod_set_debounce(map[i].gpiod,jk->debounce_interval * 1000);

then the code multiplies it by 1000 to get 100,000 microseconds or 100 milliseconds

hey, can you check something on your systems... can you run this from a shell, I'm wondering if it's set:

cat /sys/devices/platform/play_joystick/axis_to_dpad

If this is 1 then it might be the reason for weird dpad locking issues. IE if you bump the analog while using the dpad weird shit can happen.

This driver sucks though... they're multiplexing one analog input for all the analog sticks by rapidly switching between them, so you only measure a quarter of the axes each time. (right-vertical, right-horizontal, left-vertical, left-horizontal)

[quick ravine]

I am gonna need noob instructions on how to run that

[final saffron]

oh... have you ever used SSH?

[quick ravine]

Nope xD

[final saffron]

eh... no worries then.

Funny story. One time back in the day I got a bug report from Sony testing that the Playstation 2 game I was working on would lock if you hit a button twice in one frame.

The game ran at 60 frames per second.

I wrote back that that's physically impossible, so they sent over their tester to show me. He proceeded to hit the buttons so freaking fast I couldn't believe it. Locked the game.

[final saffron]

If you want to bug ChatGPT for instructions on how to install Putty SSH, you can turn on SSH on your U8 and if you can connect it to your network with a wifi dongle you can get a running command shell on it by SSH-ing as root into the IP address of your U8

You're running arkos? You'll need to lookup the arkos root password.

[quick ravine]

I can maybe try it with the x55, but I havent got a working dongle for it.

(I mean for the u8)

[final saffron]

nah don't worry about it. From reading this driver code, it seems to me this hardware is super cheap. The analog multiplexing bullshit makes me think they really skimped on everything. I don't think the lost inputs is a driver issue (although maybe it's the 100ms debounce?) but I think the locked-dpad issue might be.

[quick ravine]

Also this inmediately made me think about this other post in the k36 chat, not sure if it's related #1274131112351764532 message

[final saffron]

Dunno. I don't see anything so egregious that it would crash the system, but the way they do analog-as-dpad in the driver I definitely can see how the dpad could get stuck buttons.

[quick ravine]

I am actually concerned more with the gpio buttons misdetections. I haven't missdetections with the sticks (though i use them less). Although what you are saying is that the way it handles the analog it impacts the dpad? And as for cheap hardware, it's just odd that all the clones running ee 4.7 have this issue but other cheap handhelds with other os dont.

[final saffron]

Yeah, if you're talking about abxy misses, it may be hardware related. But yes, the analog driver definitely impacts the dpad. They have this crazy state machine that tracks your last dpad move so it's possible if you bump the analog while pressing the dpad you could get it out of whack.

[quick ravine]

I played a bit of streets of rage 2 on the rx6h using the analog stick and I switched to the dpad for the forward atack, and although I changed from analog to dpad often I didnt seem to notice any misbehaviour outside from the painful ocasional misdetections on the non analog buttons.

Could we increase the drive force of the abxy in the dtb if the issue is weak hardware?

I tried comparing with the x55, but couldnt really map the settings used in the dtb (though it should be there)

There's basically two settings for abxy detection and both are kinda like debounces. First is the actual gpiod_set_debounce which runs in the kernel and maybe the hardware and debounces inputs. I dunno how it works really. It's configurable in the dtb and set to 100ms

Next is the call to mod_delayed_work in the driver code. Interestingly this has a commented out entry that might enlighten what's going on here:

    //是否不需要使用延时 中断内不能有睡眠API
    //mod_delayed_work(system_wq,&map->work, msecs_to_jiffies(zed_joystick->debounce_interval));
    mod_delayed_work(system_wq,&map->work, msecs_to_jiffies(10));    

This basically says whenever we get an interrupt on a button press, wait 10ms and then call the work function which is mapped to gpio_keys_gpio_work_func which looks pretty uninteresting. I'm not totally sure why mod_delayed_work is needed but I think it has something to do with making sure the electrical signals of the button press stabilize before actually reading the gpio registers. So maybe making that 10 to a bigger number will add a bit of input latency but will cure missed inputs. I dunno.

Oh, but that might be why your AI thinks the debounce was set to 10ms

mod_delayed_work is a kind of debounce

Oh, ok reading the docs, gpiod_set_debounce (which uses the debounce in the dtb) is a hardware solution so it might not even do anything. mod_delayed_work is a way of doing debouncing in software.

Doing kernel driver development for these gpio buttons when we don't have the hardware engineers to ask questions sucks though

[quick ravine]

I checked on the x55 version and that part is also present. What I did see is that on the driver for the u8 there is also this line not present on the xg55 (not sure if it matters)

// mod_delayed_work(system_wq,&jk->map[i]->work, msecs_to_jiffies(zed_joystick->debounce_interval));

[final saffron]

Yeah, x55 and u8 both do the same thing, 10ms mod_delayed_work debounce. That doesn't mean that changing it might improve things for the u8 but I dunno

If you had a hardware logic analyzer you could at least see what the signal bounce looked like on button press and time the debounce accordingly, but I'm not a hardware guy I've only written drivers based on what the hw designer told me

[final saffron]

Hardware eng chatgpt says maybe 20ms

Although I have witnessed somebody do a 20ms button press... I couldnt do one. Thats still 50 buttons per second.

Does anyone have a kernel dev setup to compile these drivers?

[final saffron]

Anyways, TLDR, I recommend two changes:

1. Make the mod_delayed_work delay to 20 (from 10)
2. Make sure /sys/devices/platform/play_joystick/axis_to_dpad is 0

[hoary cedar]

or if you have joystick drift 🤣

[hoary cedar]

I think it’s hardware related as well. There’s a reason these are cheap. There’s probably too much noise they crosstalk from time to time.

[hoary cedar]

This fixes the right analog btw

[final saffron]

Yeah the way the driver uses one analog line for all 4 axes and switches the gpio line to multiplex is gonna cause crosstalk for sure.

Combine with analog-as-dpad in the driver and it seems likely that stuck dpad buttons are a result.

But you can disable analog-as-dpad in the proc filesystem.

@hoary cedar are you able to build a dpad driver with 20ms mod_dalayed_work?

[hoary cedar]

I could probably ask them to build one but not sure if they’d be able to.

[final saffron]

Oh no worries. I gave my friend my u8 so I dont have it anymore to fiddle with. Probably not worth all the effort.

[hearty iron]

oooo how do I do that? since I've definitely noticed repeating dpad inputs

but not just on the u8, on the r36 pro as well, do you know where I could find the dtb file? as I can send that one here too if you'd like since it has similar misdetections just less frequent

although it's worse on the u8 I think, could also just be that I have to press it harder as all of the buttons on the u8 are on the stiffer side

[hearty iron]

I am sadly starting to think the same, it really sucks bc I want to like it and I already own it now 😔 I just don't know how to develop

if it would help, I can also send a dtb from my powkiddy v10 if it has one as it's another 3326 device that I own

and I am pretty certain that one doesnt have missed inputs but also it runs on arkos and not emuelec

how do I run this? if you don't mind me asking, like ik from a shell and ik windows has powershell but how do I run it exactly

[final saffron]

Keep reading from the above thread. Or just ask chat gpt how to use ssh and be prepared to spend a lot of time learning a new skill

Or don't bother if learning new programming languages isn't fun for you. I fucking love this shit though.

[hearty iron]

yeahhh I will pass unfortunately, I don't like programming much, I know learning Java is like the worst one I hear, but that kinda made the entire thing a sour topic for me lol

[final saffron]

No it isn't specifically javas fault. Some people dont enjoy it. This is our hobby and if you dont like it, thats totally fine. I dont like partner dancing. Some people do.

But i fucking love coding with the passion of a million suns.

[quick ravine]

Come on, dont loose hope there's gotta be some kind of workaround to the missdetrctions

[quick ravine]

I still havent tried rocknix on the mymini, but supposedly they claim it fixes the missdetections

[hoary cedar]

if rocknix fixes it then it is the drivers

[stray cypress]

How to quickly test it?

The conductive adhesive on this U8 in my hand is way too hard😂

[ancient ridge]

I played Aria of Sorrow for 20 hours with clone devices(mymini, U8 etc) only for testing and fixing the misdetection, so I experienced lots of cases and knew exactly what it is like. and then played it for 6 hours more (with mymini 3hr, U8 3hr) on Rocknix only to reproduce the input error. Now I can tell the misdetection is completely gone on Rocknix.

[mild sorrel]

Do you have the rocknix download link for the U8?

[final saffron]

Do analog sticks work on rocknix? I'm looking at their joypad driver code and I'd be surprised if they do on the u8

[ancient ridge]

Rocknix for U8 has not been released yet. I just applied U8 dtbo overlay on Rocknix for mymini.

[ancient ridge]

sticks are not working. only RightX is.

RightX is assigned as axis0

[final saffron]

I just did a cursory read of the rocknix joypad driver and it seems to be poll based instead of interrupt driven. This makes for a much more robust button detection but uses more CPU.

[final saffron]

Yeah just one axis. This is because the u8 has to tell the multiplexer which axis it wants to read while other handhelds have analog inputs for all 4 axes.

Seems like this is fixable though. I dont have the time to work on it right now though.

[hoary cedar]

Sounds great so it just needs to be adapted for ArkOS and the misdetections are fixed. Can we somehow ask for the drivers on that specific rocknix mod? or if it was the same one that’s used by default on rocknix.

[ancient ridge]

I've read your in-depth analysis. Looking forward to some good news! I'm not sure if it helps, the volume key is assigned as axis2 (adc-channel 2).

[quick ravine]

Did you check the official one or the one in the mod?

[hearty iron]

I am glad you like it :) it's always good when ppl have their own passions

[hearty iron]

if it can be adapted for ark I imagine it can be adapted for the stock as well as idk how different they are

[honest dagger]

Just saw another m17 type u8-ish sorta xf43 thing clone on BOYHOM. What is this?

[hearty iron]

hmmmm that might be new, can you send the listing?

looks like a modernized m17 clone, I assume it has a 3128 in which case that price is awful, but if it's a 3326 then still not a great price but not as bad

[quick ravine]

Yeah, seems like a g28/xf43 reshelled.

[hearty iron]

found the listing: https://www.aliexpress.us/item/3256808592886906.html?spm=a2g0o.productlist.main.1.11ff65d1s7eoAB&algo_pvid=8d2f76c3-53d8-4be4-b339-05f1552bef1b&algo_exp_id=8d2f76c3-53d8-4be4-b339-05f1552bef1b-0&pdp_ext_f={"order"%3A"1"%2C"eval"%3A"1"}&pdp_npi=4%40dis!USD!84.65!42.33!!!614.26!307.13!%402103244417450643338051952ec041!12000046815176728!sea!US!3012658249!X&curPageLogUid=mgpOcxgdUezn&utparam-url=scene%3Asearch|query_from%3A

it's indeed a 3128 😔

[quick ravine]

For it's screen resolution (480x272) the chip is fairly decent, it wont handle very well many shaders but it can do some good video filters. My issues is that it also has the buttons misdrtections.

(Though in some listing i saw 1080p xD)

[mild sorrel]

How should I proceed to insert the dtb? Is it to add it to the root of the rocknix share and that's it? Do I have to rename it with the name of the dtb of the mymini? Thanks in advance!

[hearty iron]

I mean I guesss, it's the same as the g28 and m17, just not worth the money really

and yeah the button misdetections would suck, atp I'd almost rather have my locked down m17

I hope we can get a fix soon 😭

[ancient ridge]

overwrite this link on Rocknix mod for mymini. rotation/abxy/vol key fixed but analog sticks are not working yet. no perfect but it's enough to test a little. U8 has hardware misdetection as well, Replacing membrane(with R36s, anbernic etc) is highly recommended to expect accurate input even on rocknix.
(I disconnected the below link because the real thing came)
https://drive.google.com/file/d/1xLIqwwo1IAIc5hvooHXhHcEAofDULDP2/view?usp=sharing

[stray cypress]

The author of the R36S clone models doesn't own all of them. Both DTBs provided for A and B are from Panel 5 in ArkOS (with and without amplifier versions). For Panel 1, you can use the DTB from R36Pro. The rest of the R36S models can be modified by the community. I'm just sharing this here; you can find the original article by the author at this link: https://mp.weixin.qq.com/s/GPZSX7CRwTewqkA2wLdt9g.

[sudden cargo]

Yes

[stray cypress]

Forgot the U8's dtb

[hearty iron]

is there a way to get this working with an r36pro? I would rather test rocknix on that first personally since ik it is less likely to have hardware misdetections, so I can definitively tell if they are gone

[mild sorrel]

Well after testing it with games of various systems in which an intense use of the dpad is made, I must say that the drift disappears completely!!! Thanks for all!! A pity that the left analog does not work, because otherwise it would have been an os to leave it as definitive.

[ancient ridge]

sounds good. but improved version was uploaded by lcdyk. I tested it and found the analog sticks are working.

[ancient ridge]

you can find the link above, lcdyk kindly uploaded the version for various devices from the original author.

[hearty iron]

oh is that what that was? I might be stupid or something but I honestly didn't understand any of their message 😅 I was completely confused

I'll try it out later today and see how it stacks against stock, I still wish for modified stock to come out in the future but I will gladly use rocknix for the time being

oooo from reading the readme, this might blow stock out of the water, I do wonder if rocknix has theme support, I will definitely try it out and see how it goes

[mild sorrel]

I have burned the image and pasted the dtb in the rocknix root, but I only get black screen. should I do something else?

[stray cypress]

replacing this

[solemn tapir]

Button not work in rocknix

Button 😅😅

[mild sorrel]

Yes, with the last build not work dpad, and in RA menus are in chinese, and neither the dpad nor the analog or the buttons work either.

[ancient ridge]

actually button works but keymapping needed on every apps(ES/retroarch/ppsspp...) after installation. keyboard is required when setting up retroarch.

[quick ravine]

Guyyss!! If you copy the image file and the dtb (to rename) from this link to your akros u8 boot partition if fixes the button missdetections.

https://github.com/gamely-code/retrohandle_U8/tree/U8/arkos_image/U8

[mild sorrel]

It works great! The only downside, the battery indicator goes crazy!!!!

[ancient ridge]

yeah I tried. the input errors are gone. 🔥

[quick ravine]

Yeah, I've noticed that while charging with thr console on it doesnt update the % until I unplug it.

[regal lion]

Hello everyone, I have the penultimate version of ArkOS - ArkOS K36 (02212025).
When I change the version for PSP, the version with more options is only in Spanish, even if I change the language in the settings. How can I change the language?

[sudden cargo]

Thanks I will try this as well. 🔥 My battery indicator has been incorrect for a while already so not sure if it's related.

[quick ravine]

Here we have it ready

https://github.com/AeolusUX/ArkOS-K36/releases/tag/ArkOS.K36.04232025.U8.ONLY

[sudden cargo]

I triied the MF and MEGA links and I get archive corrupted.

[hoary cedar]

These don’t need to be extracted if you flash using rufus

[mild sorrel]

Now the dpad and triggers runs perfectly!! The only 2 issues that i've seen are the battery indicator goes crazy, raising or lowering the percentage from 50 to 0 in a matter of seconds or minutes. Also, it cannot be charged when the power is off. Whenever I plug in the cable, the console turns on, and even if I turn it off from the menu, if it is still plugged in, it turns itself back on

[hoary cedar]

Unfortunately I sold my last U8 but when I get another one I'll check those issues.

[stray cypress]

rocknix 60hz

[quick ravine]

The k36 arkos new version also has the battery and charging issue (at least for me).

[quick ravine]

Try renaming rfk38g3sa.dtb to rf3536k4ka.dtb. That solved the chargin issue for me.

[mild sorrel]

Wow! Yes, the battery and charging problems have been solved by doing what you say!!!! Thanks!!

[hoary cedar]

weird maybe naming it anything but rfk38g3sa works because it was named rk3326-u8 before 🤣

[tribal axle]

The Portmaster equivalent device to the U8 is the R36S to download games like Stardew Valley?

[quick ravine]

There are 2 DTBs in the boot, one with the u8 name and one with the rfk (both are the same file). I tried ranaming it to something else than the rf5 and the battery issue was back. So not sure. But at least it works. I seem to loose audio when I enter sleep, but the rest is great.

[tribal axle]

Someone have a problem with a black screen when turn on? The music sound but the screen dont show any image

Default installation of the U8

[quick ravine]

By default do you mean stock card??

[tribal axle]

Yep, should i change It?

[quick ravine]

I always switch them as soon as I can. Try installing the march release of arkos for the u8 and see if that brings the screen back. There is ways to reinstall Emuelec, but it requieres more work (and you need a copy of your emuelec partition).

[tribal axle]

How i can install ArkOs?
I have this partitions inside the SSD i should format the sd and install ArkOs on a clean partition?

Should i follow this instructions?
https://github.com/christianhaitian/arkos/wiki

[tribal axle]

I install ArkOS but i strill get the black screen

[quick ravine]

First make a back up of the emuelec partition and the eeroms partition. The arkos u need is the k36-u8 version. Try the march release first (link). If it works then you van later try the newer version, but it requieres renaming a dtb

https://github.com/AeolusUX/ArkOS-K36/releases/tag/ArkOS.K36.03112025

[tribal axle]

I make the backups

But i installed the last version

[tribal axle]

This one

[tribal axle]

I will try, i hope this one fix the black screen

[tribal axle]

How much time takes to fully charge the U8? I'm using 5V/2A charger

[quick ravine]

Not sure... My guess is about 3 hours but I let it more time charging. Where you able to make the screen work?

[tribal axle]

I fully charge it and now im trying to reinstall

Always black

The screen turn on but dont show any image

[quick ravine]

Did you charge it without an sd in it?? I haeard it is not recommended. Still, if you are using the arkos march image you should at least get the boot logo. Are you using a different sd from the one that came with the console?

[tribal axle]

With the sd

Im using a Sandisk Ultra sd bought on a local storage, i have a Samsung should i try it?

[quick ravine]

How large are they?? Very large card might give problems. Try with the other card, and after that you can also try Emuelec if it doesnt work (here is a link for the U8). If none of that works, then you might have to open it, but I am no expert on ribbon cables. Might also want to wait for input from other users.

https://drive.google.com/file/d/1amHjZsZt9sRZBWxTh3Rt67IJukMmEeAA/view?usp=sharing

[tribal axle]

Thanks for the help ❤️

The SDs have 16 and 32GB

[tribal axle]

Nah the screen dont show any image

With any sd or os i tryed

If someone have the same problem and want to help

[quick ravine]

At this point it seems like a hardware issue. If you feel comfortable doing it, you can try disconecting and reconecting the screen ribbon cable. Other than that I am out of ideas. Also, you can try explaining you issue to an AI and it might shed some light.

[tribal axle]

I already siconect batery and screen and clean the cirtuit of energy presing the power button without batery but nothing works, i think i Will return It 😦 i have a good price, 17€

[quick ravine]

17 is a good price, but if it's dead then return it. The lowest I see now is 25 euros (early bird), which is still not bad.

https://a.aliexpress.com/_EvyaoWA

[tribal axle]

Yes i will try to get another one

[regal lion]

I've used the original sd to restore the battery status.
I did exactly this: inserted the sd tried to start and then pressed the reset, finally inserted the console to charge. so it gave me the charging animation. At that point I turned it on and it works

[tribal axle]

I return it and bought another one, sad because the price was great (17€ and now 24€)

[tribal axle]

Any recommendations for a USB C to A adapter and a WiFi dongle that works with ArkOS?

[vale bay]

Use this combination of keys（ L3+L2+3 times Y ） to trigger the factory reset.try this method.

[vale bay]

another method : burning the ee firmware:https://github.com/gamely-code/retrohandle_U8/releases/tag/V2.0

[hoary cedar]

Just received a batch of this that has noticeably better buttons. It uses the 4/21 ee firmware so this might be a new batch.

Old batch can’t press like this 🤣

[quick ravine]

On this version I get the "press again to quit" every time I press the FN button. Wouldnt change even when changing the hotkeys. Did you notice the same??

[hoary cedar]

I’ll have to check maybe they mapped it to the fn button by default

[quick ravine]

Hmm... dont know if it might be helpful, but I got the same issue when I tried using the new u8 arkos kernel with the previous emuelec release.

[sudden cargo]

I'm still on stock, right now what's the best firmware I can put on this?

[quick ravine]

Arkos for the u8

Also, uf you have issue charging with arkos try this #1342220912057127066 message

Most game system not shows up and missin game systems in main OS card.

[sudden cargo]

I had a similar problem, I re-formatted my cards and it worked again. Not sure what the actual problem was.

[grizzled cairn]

If I only insert the OS card into the device and load the games onto it, everything appears correctly. However, when I insert a second card into the device, the operating system breaks and the theme on the OS card doesn't activate. I have to copy the theme to the second (external) card as well. The same applies to music and games.

[quick ravine]

This is the best price I have seen for The Project X Pro on ali. It should be the same as a U8 but with "grips" and wierd leds.
https://a.aliexpress.com/_EveYJWE

[final saffron]

😬 segmented dpad

[quick ravine]

Yeah, that seems to be a major downside.

[robust ridge]

Wasn't there a sort of another U8 with slightly protruding grips but not like this? With a circular D-pad, bottom, and ambient lights?

oh, the RX6H

[quick ravine]

Yeah, i really like that one (minus de shield dpad). But it's a 3,5 4:3.

[hoary cedar]

The screen on this is different

[quick ravine]

It feels like a pro version of the u8 (better screen, buttons, and grip). The segmented dpad actually feels good.

[hoary cedar]

not the same screen ratio

[quick ravine]

Nope. Although the U8 screen seeems to fit iin the bigger one xD. But supposedly the u8 is 4inch 800x600 while the pxp is 4,3inch 800x480, so less ppi. The U8 screen is still special, but it lacks some vibrancy.

[hoary cedar]

hold up if it's 800x480 then its also 5:3 😲

Why does this say 3128

[final saffron]

U8 is 800x480

[quick ravine]

Yeah, there are some listings like that. I think they are from the original project x. I asked one of the sellers and they told me they also had the rk3326 version. But I ended up choosing a seller that had thr correct info

[final saffron]

Lol 3128 with 4gb of ram... Riiiight

Somebody should make a 3128 handheld with 4gb of ram and call it the e1000

Still, the rg34xx-sp points to a future where 2gig chips are easier to come by than 1gig and cheap devices will just have 2gigs

[hoary cedar]

does the black also come with the same metallic coating? I don't trust those especially for devices you always hold. Sweat will eventually erase it 😅

[quick ravine]

It feels more like "glossy" paint

[hoary cedar]

Yep im gonna pass that becomes black 😂

[slate cairn]

Hey all. New here but just to chime in regarding button inputs on the U8, this is one I've been tinkering with a lot and what made the biggest impact was cutting the tethers between the face buttons. The loop on the tethers on this system are too tight to the point that they damage functionality. I found when I was pressing the A button, the left side of the button compressed far more than the right side, resulting in a lot of missed input. These feel absolutely fine now after doing away with the tethers.

[tribal axle]

I have a U8 handheld running ArkOS. I recently installed the Cody Destroy theme, but I'm experiencing an issue where the emulation categories don't expand or display properly in the menu. Has anyone encountered this problem or knows how to fix it? (Game list displays properly without problems)

[hoary cedar]

Some themes are just not made for some screen ratios

Only fix is if you edit it yourself

[tribal axle]

Okey, thanks for the help

[carmine belfry]

hello i just got mine today, could this also be the newer version (or batch)?

[hoary cedar]

if the buttons feel good then yes

[carmine belfry]

yxab feels nice and clicky, yes

[hoary cedar]

first batch is hard to press

[carmine belfry]

the body is much better than my myioo a30

now i just have to figure out how to install the portmaster thingy

[final saffron]

The question is, are the analog sticks still wired to multiplex over two wires or did they break it out to be independent signals?

[carmine belfry]

i have no idea how to check that 😨

[final saffron]

I think I have a photo of the motherboard somewhere and we may be able to see the traces. Probably not though. We only know because somebody, probably aeolus, got the driver code. Still would be interesting to see a pic of the board.

This seems to be the only pic I have

[carmine belfry]

i'm a bit scared to open it up as i'm really clumsy and afraid that i'll break something 😅 but i think the sticks have the two-wires thingy

[final saffron]

Its impossible to tell from
pics but thats a good idea to not open it up. The u8 is the most fragile handheld I'd ever seen. I broke mine.

[final saffron]

Those wires are the battery and speakers

[carmine belfry]

interesting

[jagged haven]

I tried to record myself when I opened it up but I got so involved in not breaking the thing that most of what I did ended up out of frame. May cobble together some of the usable footage anyway but it won't be very useful.
Anyone looking to open this, use a magnetic tip precision screwdriver - YOU WILL LOSE TINY SCREWS INSIDE THE THING OTHERWISE

[final saffron]

You have the new one?

[jagged haven]

Think mine is the older model. The one with the terrible face buttons that need to have the tethers cut to actually press properly (hence why I opened it)

[final saffron]

ah, that's what I had in my picture above so not so necessary to see a pic of

[jagged haven]

I spent most of the time trying to fish tiny screws out of the shell 😅

Is there an AliExpress store that's definitely selling the newer model? I'd be willing to buy one and record myself opening it up, for science.

[final saffron]

nonono don't do that, this thing is total ewaste and there's only a very slight chance they spun around and fixed it's issues. The newer boards on the R36s Plus keep getting iterated with internal wifi antennas, etc, and it's the same price. I had a lot of hope for this device because the screen does perfect GBA integer scale, but so do the 720x720 screens.

[jagged haven]

I hated the device until I put custom firmware on it and cut those damn horrible button tethers. Now I actually really enjoy using it

[final saffron]

I think the 800x480 screen is a really cool aspect ratio for low power scaling and I'm surprised it's not used more often. The hardware aspects of multiplexing the analog sticks and the driver-level stick-to-dpad translation makes this device a total hassle for good portmaster stuff which is what I wanted to use it for.

The U8 uses one signal for all 4 dpad axes (L-vertical, L-horizontal, R-vertical, R-horizontal) so it gets confused if you're using both sticks at the same time. it also tries to map sticks to dpad entries at the driver level which is wonky. In comparison, the r36s has indipendent traces on the board for each axis so it can read them all at the same time.

[sudden cargo]

The SJGAM M26 that just came has this resolution at 5.1”. I think it’s great. I just got it.

[carmine belfry]

anybody knows how to change stickers controls on render96ex/mario64? i've tried messing around with the config file on wordpad but it still uses the default mapping/binding

UnofficialOS support incoming🙂

[hoary cedar]

Do you mean the guys that made this device are scums

[stone idol]

Lol..I honestly don't know who makes this device.. every time I Google it it has a different name.. the person who sent it had your version of ark in it which worked well.. it was a little harder then most clones to get going with the rotation, but it's all set.. mini m is next i think

[stone idol]

@hoary cedar hey u have any stability issues with the u8.. I'm wondering if I need to tune the regulators more to that device in the dts I'm using
It is fine as far as es, but once u play a game for 10 mins or so, it just shuts down.. I'm wondering if I need to adjust voltage more maybe?? What's your thoughts

Someone tried to use USB C headphones on the U8?, i dont know how to make It work

@hoary cedar ArkOS4Clone have support for U8?

[hoary cedar]

You might need to ask @stray cypress for that I don't have one anymore

Should be possible #1274131112351764532 message

I haven’t started tinkering with this device yet, but if it works properly without replacing the binary emulators, I’ll definitely add support for the U8.

The U8 is one of my mainly used systems, so if anyone wants me to test builds on it then more than happy to. As a side note, the Diium D28S (which I also have) can run the U8 build of ArkOS when swapping out the DTB, think it uses the same screen rotation or something but may be easy to add support for that too.

[tribal axle]

Do you currently own the console, or would you need to buy it? I could help test the builds when you start tinkering with the console

[stray cypress]

I have this device now, but I haven't done it yet

U could test uOS on it if u want..u just need to set panel rotation to 270 in the overlay and invert the right stick. Besides that it's all set afaik

I bought one also cuz i like it.. the 5:3 screen is a nice touch

[jagged haven]

I shall give this a try

The only other quirk is the led doesn't work unless charging.. all the clones are like this right now because of the way the dtb is.. the units all handle the leds different

I just added 3 new xtreme cores to 3326 and 3566 also, fixes n64 performance issues and adds some performance to dc as well.. will be out with the next release soon

Good news for clone users on UnofficialOS, next update, the boot.ini will only need an edit one time when the sd is flashed. Then the user flips the switch on first boot, and can update ota like usual.. if the clone had audio issues (r36s clone/r36 ultra/s600/batman units), no problem, flip the other switch, and the v2 dtb gets set automatically, and will also persist thru ota updates🙂 👍

[hoary cedar]

is that in the danger zone

[stone idol]

No, right under system settings in es..

[hoary cedar]

I think that's better hidden or you'll see people start "accidentally" toggling it. Or is it possible to add a warning?

[stone idol]

It has a warning

And then it had to reboot to set the right dtb
