But it has a Sega logo on it. That makes it special

@hollow turtle Late replying here. But as others have implied, I'd gladly purchase a 3D glasses SMS/Genny SNAC adapter if you made a run. I've got a few CRT's and even picked up a Sony Playstation 3D panel all after and because of MiSTer.

[livid spire]

Same here. There are other people making SNAC adapters, but if you'd need a smaller interested base for something like this, count me in for one too!

Did it require custom cores too out of curiosity, or is it already accessible from the current core?

[hollow turtle]

Sorry it's taken a while, but I've been helping in the garden etc., then my brother's birthday on the weekend.

That's an old compile, but it still seems to run fine on my MiSTer setup.

It has the options for Side-By-Side 3D output, for 3DTVs. That's the part Grabulosaure kindly added.

The Side-By-Side 3D won't look very smooth, as it kind of updates each "eye" in turn.

So you only get 30 Hz per eye. Hard to describe.

There's also an option for shrinking the SBS 3D output, since the parallax might be too wide on larger modern TVs, even with low Depth settings in the MiSTer menu.

The core does also output field-sequential 3D via CRT.

And outputs the 3D signal on one of the SNAC pins, IIRC.

I can't recall which version of the 3D shutter glasses adapter worked best. I'll have to dig out some old DMs with Bob etc.

This is all very experimental, of course. Just a bit of fun, and something I'd been wanting to try for years.

It would be possible to output SBS 3D with both "eyes" updating at 60Hz, but would require much bigger tweaks to the core.

(the same tile data gets fetched from VRAM for the background layers for both eyes, it's just get shifted horizontally more than the other. There might be a way to do 60Hz per eye, without needing to duplicate big chunks of the VDP.)

There is no 3D Depth option for sprites atm. That would be quite hard to do.

Sprites always sit at the same 3D depth "plane" as the screen.

I barely tried any games on this core (at the time).

But games like TMNT can be fun, as that game has a lot of interesting stuff on the foreground layer.

You can set the depth of each background layer to be positive or negative. One of those "directions" will probably look very wrong. lol

[livid spire]

Thanks for all the info! Curious was the SNAC adapter ever tried with the SMS core? To be able to do the official 3D glasses games as intended on MiSTer? If it were to be added to the "Mega Drive" core now rather than Genesis, I guess the implementation in one core would give the benefit of both perhaps?

The next issue will be getting a hold of the SNAC adapter (or working out how to build one, which seems a tall order 🤣 )

[hollow turtle]

Yep, the SNAC 3D glasses driver was tested with the SMS core briefly. I believe Bob might have tried it with LCD glasses on a CRT, too.

[livid spire]

The SMS use case alone I think would probably get lots of interest, though the background layer Mega Drive sounds like it would be great fun to try out

[hollow turtle]

I can't remember if it was blue1's design for the SNAC part?

It's the old-style voltage translation with the FETs, though.

One of the signals gets routed to the 3D glasses driver, which I had to figure out, from schematics on Sam's Laser FAQ and other places. lol

Using a capacitor charge pump chip, to get +/- 10V or so.

It was only about 3-4 years ago, but I don't remember if it had any major issues.

I just recall Bob saying the original SMS glasses worked a bit better (on a CRT), than the Asus ones.

[livid spire]

For one tip to improve visibility with the modern shutter glasses playing SMS games, try wearing sunglasses underneath the modern glasses. I think they just don't darken the outside world enough to help dull the latent image from the previous eyes frame (at least on a CRT where I would imagine some of the after image remains, especially with white on black content).
Sunglasses is a quick and dirty fix! Or get some ND filter

[livid spire]

Those are the ones yeah

[hollow turtle]

Yep, and quite a few modern (wireless) glasses for 3DTVs will have an overlap timing for the shuttering, too.

That's something that could be added to the core, but it would need separate Left / Right signals on the adapter.

Could even generate the IR signals for modern LCD glasses direct from an FPGA / SNAC pin.

[livid spire]

If the current SNAC would work with the official (or ASUS ones), that would still be a great starting point. Not familiar with the different meaning in old-style voltage version you mentioned. Is that just whether you need to have the little voltage break out board between the adapeter and IO port?

[hollow turtle]

I should be up-front, and say - I don't know if I'll ever get around to looking into the SNAC adapter again. 😦

But I'll put the files on github soon.

[livid spire]

Thanks very much for the work you have done! Just knowing someone had gotten so far into it is great to hear as a hapless user not skilled at the development side, hoping for 3D SMS games someday. If you do never go back into it, hopefully it will be there for someone else knowledgeable to keep running with it.

[hollow turtle]

Looking back on some of the old Bob chat, and sheesh - it's no wonder I have trouble finishing projects. lol

I was trying to do WAY too many projects at once.

One project I was testing at the same time, was the Quad VGA/RGB board...

https://media.discordapp.net/attachments/811777763387899925/831261328249192478/20210412_211434.jpg?ex=681a6df0&is=68191c70&hm=c48bb19de46a90be3799d66426496162b09111ffd6954b706e92a80f33709da0&=&format=webp&width=2642&height=1487

I only had the one CRT test each output on, but it essentially lets you output up to four separate video signals to each monitor, simultaneously.

I always liked the idea of using transparent OLED panels, to build a kind of "3D" showpiece of older games.

[livid spire]

That sounds fun alright. Like those 3D diorma images you can get as framed gamer gifts. Only playable Sonic 🤘

[hollow turtle]

Yeah. hehe

I found some Gerbers and BOM for the SNAC DB9 / 3D adapter, but best not to post them yet.

I vaguely recall having to tweak the design for the charge pump, or something.

We were... planning on selling a few versions. lol

The Eagle files look OK.

The glasses driver is basically just that.

A MAX660 charge pump chip, and a 4030 switch IC, for the oscillator and Left / Right driver.

Oh, and I had the 3D glasses pin hooked up to the Start/C pin.

So you wouldn't be able to use those buttons in 3D mode.

(3D glasses output is enabled in the core whenever the SNAC option is disabled, IIRC. So you'd have to use a USB joypad if you wanted to test 3D with all the buttons working.)

If that makes any sense at all. lol

[livid spire]

I think that makes sense, if a little odd sounding at first! I guess unless such an adapter could have enough space and capability to run a full DB9 controller port (in addition to the 3D glasses input), you'd be stuck to do any better....

Though I suddenly recall the 3D glass + Light Phaser game, so if SNAC could do both at once, there is a use case

Missile Defense 3-D

[hollow turtle]

SNAC is great, and all, but never quite enough pins for all the goodies at once.

https://media.discordapp.net/attachments/528262687042306058/822139917743423558/20210318_160950.jpg?ex=681a3477&is=6818e2f7&hm=4f60afe7224acca7711f4729a8b344561d9b9cc358adf0a1bc4372a2cb019ef5&=&format=webp&width=2642&height=1487

I remember now.

That bodge, was to test the MAX660 chip, since the original charge pump circuit didn't work.

If I get chance, I'll try to dig out the old adapter, and test again on the CRT.

But the CRT isn't even in the same room as the MiSTer setup atm, and I have no idea where the old adapter is. lol

I probably have some bare PCBs, though. Easier sometimes to just order the chips again, and build a few more.

Wondering if "modern" 3D shutter glasses would look OK on a CRT.

As it would be a lot easier to just drive an IR LED from an FPGA pin.

[livid spire]

Though there may not be all the pins you need, I'll choose to take some encouragement from the fact it looks like there's a DB9 alongside that 3.5mm input on that SNAC board 🤣

[hollow turtle]

Yeah, just have to sacrifice using both at the same time.

Or, I think when it was using the DB9, pressing Start or C on a Genny pad, would cause the glasses to toggle. lol

[livid spire]

Bob seemed to ask a similar question on options for supporting SMS 3D glasses and such on a recent video. Could have been from the perspective of adapters for SMS consoles, but similar anyway. No idea if new glasses would look ok.....

[hollow turtle]

Might be easier to just test the core on a 3DTV.

The faux-3D effect might disappoint. lol

When I tried SMS 3D games on the 3DTV (47"?), the parallax was WAY too wide.

[livid spire]

It might be enough to have partial DB9 with 3D. Not played the 3D SMS games in a minute since my Mega Drive broke, but I you might get away with Start.... And C would be Button 2... hopefully....

[hollow turtle]

No amount of adjustment would stop me from going cross-eyed.

The Genny 3D core at least lets you add a more subtle amount of depth.

(it's just the steps of adjustment are quite big, due to the low res of the core/games.)

(SMS 3D was just testing Grabulosaure's tweaked core. I think the only thing I added was to output the Left/Right signal via one the of SNAC pins.)

[vital idol]

Do they have to be running at the same refresh/resolution? could this work for computers that supported dual output (c128)

[hollow turtle]

I basically used a set of Latch chips.

So you could latch the Hsync, Vsync, and RGB into each chip, for each display.

But that does mean that the different video signals from the core really need to be in-phase with eachother.

I mean, I guess as long as the "clock" signal to the board is a fast enough multiple, it might be possible to have completely different sync timings for each display.

(RGB doesn't need to output the pixel clock, of course, so yeah, you could in theory have different sync timings for each output.)

It would likely have some visibile jitter, though, if the "master" clock to the latches wasn't a multiple of both (core) pixel clocks.

[vital idol]

Makes sense.

[hollow turtle]

That was the Dual VGA/RGB version.

Which was combined with the Vector XY thingy.

Yet another project I never got around to properly debugging. lol

It did "half work" on the o'scope, but the Vector part had some problems.

The old SNAC SPI DAC version of the Vector board actually worked better.

The Dual VGA / Quad VGA part was quite reliable, but it had to steal some of the MiSTer LED signals, to use for the latches.

(which have now also been used for the DAC on the 24-bit IO boards. sigh)

As it happens, I used basically the same DAC chip on the board above, for Vector X/Y output.

[heady harness]

I'd gladly sponser/throw-some-money at this. Again, no pressure, work on what you want to work on. But I'd love SMS 3D Glasses SNAC support. Of what's doable, it seems like a glaring ommission. And while I lack the technical skill, I'm happy to contribute in whatever way I can.

[timber bear]

Is it possible to play Sonic 3 with the Sonic & Knuckles addon on the MD core?

[versed rapids]

There is a hack for it that merged both roms and playable on the core

[worldly dust]

or you can just paste the contents of "Sonic3.bin" on top of the Sonic & Knuckles rom by yourself

or, even better, just get Sonic 3 Complete

[amber gulch]

Or better yet instead, don't play Sonic.

[manic ridge]

Damn another user banned

[void eagle]

Running sonic and knuckles through a cart dumper with a cart attached produces a combined rom.

[amber gulch]

So is there any real usecase for a combined megadrive/32x/cd core? Or can all the games be played via romhacks?

[warm carbon]

Are the 32x cd games playable?

[drowsy hemlock]

Yep

Sonic 2 + Knuckles requires a specific hacked version, but Sonic 3 + Knuckles (and Sonic 1 + Knuckles, if you want all the blue sphere levels) don’t require special versions 🙂

[vital idol]

Doom resurrection 32x benefits from the full tower of power. Other games are mostly fmv

[manic ridge]

No

There are only a few and that's the only other thing you're missing out on

[livid spire]

IIRC my version of doing just that won't boot on the old Genesis core at least

[eternal sonnet]

What does "Minimal" audio filtering do?

[pine crystal]

It filters it minimally. 😏

[eternal sonnet]

But how does it minimally filter?

[pine crystal]

Not sure... just couldn't resist being a smart-ass. 😄

[eternal sonnet]

Robo Blast Machine Broke (it’s locked up)

[pale plover]

Basically adds a minor amount of filtering to the audio. If you want fairly clean audio but also want to tone down some of the harsher sounds, then choose minimal.

[eternal sonnet]

How new is the 32X core?

[fallow dome]

Yeah, SRB2 is an extremely early and buggy port that just served as a proof of concept. It will freeze often but it’s an amazing effort and I really look forward to its next release.

[pine crystal]

The 32X core occasionally gets updated whenever there are compatible updates to the Saturn core that can be carried over to it.

The most recent update is in the pinned comments.

2025-05-01

[eternal sonnet]

No wonder the 32X core feels a bit under-developed when no one is actively working on the 32X exclusively, and it's not as major addon to the Genesis as the Sega CD.

[warm carbon]

grab the pinned version - it's in pretty good shape

[pine crystal]

The 32X itself was under-developed... 😏

[manic ridge]

How does it feel underdeveloped?

[warm carbon]

it's a grower not a shower

[pine crystal]

The Gexual innuendos have moved here now?

[eternal sonnet]

Can we not?

[manic ridge]

The 32X has has its own set of innuendos

32Xual you might say

[eternal sonnet]

Stop.

[warm carbon]

we, quite literally, cannot

[manic ridge]

https://tenor.com/view/hiding-dont-talk-to-me-eating-my-lunch-abbott-elementary-abbott-elementary-gif-gif-25023219

[pine crystal]

It is being actively developed. It's currently in a state where it's about as good as it can be, with the exception of improvements that it benefits from due to active development of the Saturn core. Not sure what else can be expected at this point.

[warm carbon]

it's in the same spot as the saturn core

[eternal sonnet]

Ok, I was being unfair, I'll admit.

[warm carbon]

fix one thing, break something else

[manic ridge]

I don't think there's much left for bugs in 32X is there?

[warm carbon]

I think everything is completeable though, no?

[pine crystal]

Not many outstanding issues... but it's not like the library is huge to begin with.

[warm carbon]

ahh, MJ beat me to it

https://tenor.com/xJ2P.gif

[fallow dome]

How so? All the games I’ve played have been pretty much perfect.

[eternal sonnet]

https://youtu.be/WSLSY0NmnuE I assumed the frame rate of SRB2 32X was better then it was.

I then blamed MiSTer for the game’s issue.

[fallow dome]

Can’t judge the core on a barely functioning proof of concept.

[eternal sonnet]

Given the video (which I didn’t actually finish watching until after I sent it here) says that the game has issues on real hardware vs emulators, the game is likely to blame for the slowdown.

MiSTer is too good for it.

[fallow dome]

Yeah it’s all good, amigo. If you haven’t played the original game on PC it’s pretty cool.

[eternal sonnet]

I should get around to playing it sometime.

[manic ridge]

Does it run worse framerate than this video

[old sierra]

The core is in a very good state, it is just a shame that the one game I (and presumably a lot of others) want to play the most, Knuckles Chaotix, is the one that has issues

[warm carbon]

Does it have issues outside of the intro crash? I can't remember

[pine crystal]

According to the issue title (but not description), it supposedly happens during idle gameplay as well?

[fallow dome]

Seems to run just as bad

[barren plank]

https://h0ffman.itch.io/metal-gear-md

[manic ridge]

Whoah is that the MSX version?

Oh Amiga

Is Amiga the best?

[fading hare]

Sounds like the Amiga version was also a fan made version by the same person.

[manic ridge]

Oh wow

[narrow panther]

Based on a full and commented disassembly by Manuel Pazos of the original MSX2 game cartridge, this Amiga port has been built to ensure as near a perfect conversion as possible. Gameplay elements remain intact while additional features have been layered on-top to ensure the fullest experience possible of Metal Gear on the Amiga.

[manic ridge]

That's badass!

[fringe zodiac]

I guess that some sort of keyring option would have been a great addition

The Keycard management is quite demanding

[kind quail]

Metal Gear!??

[amber gulch]

Yeah, tested it this morning, works great.

Remember to set the controller to 6 button in the osd if you choose so in game, else the controls will be all messed up. Got me confused for a good 10 minutes until I remembered.

[prisma hill]

Yea, same lol.

[long cairn]

Hey friends. Has anyone noticed that at some point in the last few months, the Sega CD core stopped playing games properly that once worked? Eye of the Beholder now locks after the “Sega” logo, and Golden Axe in the Sega classics 4in1 collection now goes into endless reboot after selecting a character? (Happened to me twice on my twitch stream last night). Both of these games worked a year ago with no problem.

https://www.twitch.tv/zophar1/clip/CulturedSucculentMallardTinyFace-2hEZPKZJ0AOsgYq4

Sega CD core 24.04.08; MiSTer v250305; OS v241008

Just ran update_all and upgraded to OS v250402, no change, bug in both games persist

[barren plank]

Eye of the Beholder works fine here. I have it setup to use a Japanese BIOS, as it will not work with an US BIOS

Mister Main 250430 and MegaCD 240408

[tulip surge]

'Sega Classics Arcade Collection (USA) (4-in-1) (RE2)' seems OK here with same core etc

your main version is different than mine, are you using unstable / nightlies?

[warm carbon]

that’s the latest stable version of the megacd core i believe

what version are you on?

[long cairn]

yeah same core i have

but my main is different

Sega CD core 24.04.08; MiSTer v250305; OS v250402 over here

[tulip surge]

same here

[warm carbon]

ahh yeah, looks like they are on the unstable

[long cairn]

hmm, let me try to figure out what's different for me

Sega Classics Collection (USA) (4-in-1) (RE)

that's the name of mine. CHD format.

[tulip surge]

chd here also

might be worth renaming \config\MegaCD.CFG and seeing if it helps

[long cairn]

lemme give that a shot, sec.

assume you're thinking maybe the config file got corrupted in some way

[tulip surge]

yeah and ruling out any non default settings

[barren plank]

yes, unstable main in my case

[long cairn]

well shit

that worked for the 4in1!

lemme try eob

[tulip surge]

nice 🙂

[barren plank]

I had problems with MegaCD games before, which is why I have seperate subdirectories for US and JP releases, combined with appropriate BIOS files

[long cairn]

and eob works too now, wow!

thank you so much @tulip surge and everyone, appreciate you all

[plain quiver]

No issue on my configuration for the two games.

Ninja'ed

@tulip surge was faster.

[tulip surge]

NP. I messed with a few things like sprite limit but couldn't recreate it, easiest to nuke from orbit and start again 🙂

[long cairn]

i wonder what the heck it was in that config that created those issues

Hey guys, I know MisterFPGA have sega mea drive/cd/32x cores. Will there be a plan for future support for cartridge and CD physical medium?

[plucky flare]

no

Taki is doing some sort of physical cd media for his psx superstation, but that's outside of the official mister project and I think may only be focused on psx

[loud tiger]

Ya'll seen this game yet?

Yuzo Koshiro doing the soundtrack.

New Genesis game!

So cool

[torn dome]

my guy i’ve been following it since Koshiro said he should make a modern game for MD too

also a pox LRG

[fading hare]

Oh yeah, I've been looking forward to Earthion for ages. Can't wait for it to release!

[glad aurora]

I am super pumped for Earthion

[latent stag]

heres a dumb question.... i see we have (well at least i have) both a genesis core and a megadrive core. currently i use megadrive for all my sega md/genesis games. is the genesis core for some other system called genesis or is it redundant? OR is the genesis core the one to use?

[vital idol]

Just hope there is an alternative to LRG as a supplier.

[drowsy hemlock]

#1096614378968727652 message

Mega drive is the new one. Genesis is deprecated

[latent stag]

ah isee. i didnt see that message before. thank you

[drowsy hemlock]

No problem

[chrome moss]

Agreed! I hope they just sell them direct but at this point I assume it’s a done deal and won’t change but we can hope. Who else could realistically produce the package besides LRG? Retro-bit? I’m not privy to who all makes physical games on carts these days.

[fallow dome]

Need to make pins for this channel

[velvet mural]

Well, I don't think you want Fonzie/Watermelon making it...

Doesn't Bitmap Bureau do their own Megadrive Carts ?

[chrome moss]

I think the super sega FPGA guy is the hero we need.

[velvet mural]

I think that would be a step down from Watermelon

[narrow panther]

Neofid make nice carts

[twilit thistle]

Play Asia maybe??

[chrome moss]

I’d buy from play Asia. Always had good experiences there.

[twilit thistle]

Agreed just too bad LRG is involved and I want Koshiro to succeed I really do. I won't pirate it but I won't buy it or anything from LRG ever again.

[fallow dome]

I’m sure Yuzo Koshiro will do just fine

[plucky flare]

what if this is what he's hoping will get him out of massive gambling debt

[chrome moss]

I’ll still buy it if it’s my only option but I won’t pre-order it. I’ll wait for reviews to make sure it’s legit. I want it to be a big enough success that companies start making more retro games for actual retro consoles

[vital idol]

Ltd run games is only preorder?

[chrome moss]

Not always. Depends on the game and version

Maybe we will need to track any possible regression with it for some time.

I have a weird thing going on with the newer Genesis core. On either HDMI or RGB I get a more blurry image out of this core. The old Genesis core works brilliantly and is sharp on either HDMI or RGB. Is there anything I can do to get the newer core to not be blurry? Thanks in advance.

[pine crystal]

Is Composite Blend enabled perhaps?

[still scaffold]

I will check that.

[still scaffold]

That was it. Thank you. Now the core looks sharp on my Sony PVM.

[split stratus]

I think paulb-nl’s fix above is right, but it’s hard to say for sure without input from NukeyKT. Still, testing the changes would be great.

[glass shale]

Unfortunately nukey has left this server

[manic ridge]

Wait is it a Sharp or a Sony

[still scaffold]

It's a Sony.

[night cape]

Composite blend is blurry, but shows the intended pseudo transparency correctly.

[pine crystal]

For Saturn, too... thankfully.

[opaque kiln]

So, I'm trying to get Night Trap to run. I see the S32X core only takes .S32X files, but I have found nothing in that format. Everything is .CHD or bin/cue, which even after a rename will not load. Trying the files on the MegaCD core just says I need the 32X attachment to run.

I'm sure there's documentation I'm missing. Any tips?

[sage prairie]

You cannot play CD games that require the 32x, neither the 32x core or the MegaCD core has room to support the combination of the currently seperated cores.

[opaque kiln]

Thanks, I appreciate it

[fallow dome]

To add to that, Night Trap does work but you'll need the Sega CD only version.

[opaque kiln]

Great. Thanks for the help.

[formal summit]

Does anyone have issues with the newer mega drive core analog out over direct video? My video shows up, but seems to be more purple in color.

Might be an issue with my crt, but all other cores look like they should over direct video (including the older genesis core)

Going direct video to component

[spring lantern]

I’m having issues with colors on composite. I don’t have a component cable to try.

[warm carbon]

what games are you both trying?

I'll take a look

[spring lantern]

This is the specific issue I’m having. Not sure how relevant it is to nate’s issue because it specifies that component appears correct. The severity varies for me every time I load a ROM, so maybe that affected the reporter’s results with component.

https://github.com/MiSTer-devel/MegaDrive_MiSTer/issues/60

I was flipping back and forth between Sonic 2 and Sonic & Knuckles, and both were affected

[warm carbon]

crap, I have svideo hooked up. Let me see if I can find a composite cable

I can't find a cable anywhere. Ordered one

[formal summit]

Interesting, I think it could be related but yeah mine is slightly different- everything just gets shifted purple like the green signal is underpowered

[formal summit]

I'll send some screenshots but the issue is apparent on most games like you could throw sonic on there and see it in my case

[warm carbon]

are you also on composite?

[formal summit]

I'm direct video to component

[warm carbon]

ok, i have that setup downstairs. what cables are you using?

[formal summit]

So the laser bear setup for hdmi->vga->component female, then male to male component cables into the crt (they're the hd retrovision cables)

Normally I actually run through a component switch also, currently isolated from that but the issue is there regardless

Thanks for testing

The retrotink 5x is my only other component input and it also doesn't like the signal from this core for whatever reason

[warm carbon]

what CRT are you going into? And I assume it's ypbpr and not rgb > ypbpr?

[formal summit]

Correct yeah just component, going into my Philips crt

Random wonderswan moment there just the first picture that popped up

[warm carbon]

That’s direct video > Saturn out on io direct board > ypbpr. Does the SOG switch help at all?

Cleaner pic in this video

[warm carbon]

Realized I could do composite out on this muti cable. Not sure if it’s helpful as it it’s still DV through a dac

[spring lantern]

Could be the camera, but Tails is looking fairly radioactive in the composite pic. It might get slightly worse if you reload the ROM. FWIW, I’m using an IO Direct as well.

[formal summit]

I'm using the digital Io board but thanks for taking pics. I'll take some when I can to compare

[warm carbon]

Pretty sure it’s the phone. It’s a Live Photo and I was looking for a good frame without the scan. Had to go to the beginning of the photo. Here is one with the scan

that DV > io direct > MA multi saturn cable

I can look at it more if you’d like, though. I didn’t notice anything weird looking while taking the pics

[cloud otter]

Whatever it is, is has the acronym for Just Very Clear on it. A zenith of achievement. San,yo in for a treat.

[formal summit]

Can you see it from here

Like base white is pink

It's kind of hard to convey in these pictures actually lol

Here's the old genesis core

It's tough to see in phone pictures lol but you can see it clearly in person, white is a light pink and everything is slightly purple

[spring lantern]

Phone is probably correcting the white balance

[warm carbon]

Yeah, getting phone pics of crts is silly hard

[formal summit]

But yeah it's digital I/o I've also tried the different hdmi color range options but no difference there

Again most cores look great

[warm carbon]

Is it basically just mega drive Genesis?

[formal summit]

Yep as far as I know; mostly play snes and Saturn on the crt but I haven't seen it anywhere else

Sega cd looks good

Sonic CD looks so good in general

Very cool game

[warm carbon]

It’s a good one. Someone smarter than me will have to chime in but, iirc, genesis did some wacky stuff sync wise and that may be what you’re seeing here. It could be your set doesn’t like it. The genesis core isn’t as accurate (not that you would likely notice) and that may be why it works ok

There is an updated core pinned if you don’t have it already

I assume you do if your setup is working for you

[warm carbon]

Hmm, it’s not pinned anymore. i wonder if robby pinned the wrong one #1096614378968727652 message

that’s the genesis core with the updated framework for 9.2 IO boards

and whatever fixes the framework update brought

[formal summit]

ty

genesis is really meant for composite anyway

but it does look pretty great over component

[spring lantern]

That’s the older core, no?

[opaque kiln]

I mean, I can see why you would say that. It's just funny considering almost half of the people playing it primarily experienced it via SCART/RGB.

[warm carbon]

that's the older core updated with the latest framework

[spring lantern]

Does the newer Mega Drive not have it yet?

[formal summit]

good point haha I mostly mean for the transparency effects. sonic looks good af in rgb

[warm carbon]

it does, but the older core may fix your composite issue

[spring lantern]

Oh yeah, it definitely works correctly in that core

[plain quiver]

Rise and shine!
The last version of the SH7604 module is implemented.

I quickly tested : Tempo, DOOM, MKII, Virtua Fighter, Virtua Racing + some romhacks : DOOM Resurection, MKII Arcade Edition, Golden Axe 32x.

Letting you test some more intensively, I need to check some parts of the Saturn today.

[normal rivet]

Thanks for posting this. Hoping it fixes Knuckles

[glad aurora]

Hope this fixes the massive slowdown in Blackthorne!

[normal rivet]

FYI, Knuckles is still broken. Hung/crashed after 30 minutes or so in Attract mode.

[plain quiver]

So it's something outside of the SH7604.

[warm carbon]

My money is on “Knuckles”

[glad aurora]

I'll give Blackthorne a try here tonight and see if it still has massive slowdown

[glad aurora]

So good news

Blackthorne has no more slowdown with that core that @plain quiver shared earlier today!

[dawn ginkgo]

Mortal Kombat II still have slowdowns on today's build.

[glad aurora]

That sucks

[fallow dome]

Ok pins updated

[woeful goblet]

The last 32X build that knuckles was working fine for me was the unstable from 20241121

[plain quiver]

I will take a look on the 32x later.

[woeful goblet]

Thank you! If you could take a look at it would be great 🙏🏻

[plain quiver]

Could you recheck that version please ? @woeful goblet

Seems to work fine for me, as I'm searching the starting point when it failed.

[plain quiver]

S32X_20250113 definitively failed for me.

[warm carbon]

Am I just running the intro and seeing if it hangs eventually?

[plain quiver]

Yes.

I think something broke between the 2025-01-06 and 2025-01-13 versions.

[warm carbon]

ok, i have it running on 4 misters. two de10s, a qmtech, and a mister pi

[plain quiver]

The 01-06 version seems fine since an hour on my end.
The 01-13 one failed on all systems after 4-5 loops each.

[warm carbon]

so something that has been bugging me and I think I have confirmed via videas of real hardware: the intro music is balanced wrong

the bass is too forward

[plain quiver]

I can't do anything on it.

[warm carbon]

is it known?

[plain quiver]

No.

[warm carbon]

I was just going to file it if not

ok lemme get some audio

[plain quiver]

We need to be really sure.

[warm carbon]

To confirm, is this how the intro sounds for you?

[plain quiver]

How did you record it ?

Too much distorsion and reverb here.

[warm carbon]

put my phone next to it

[woeful goblet]

Sorry I am not at home right now but I will test it as soon as possible. Thank you again for looking at it

[warm carbon]

https://www.youtube.com/watch?v=0XJBn18bUcI it's subtle but the mix sounds different versus my mister. see if that sounds different when you get a chance

[plain quiver]

I have a reference recording of the game, directly taken from the headphones output.

Don't use Youtube or compressed video/audio that will not give a correct frequency response.

[warm carbon]

well either way, not something we need to address in this moment

[plain quiver]

And your TV amp and/or speakers seem to overbleed the bass section of your recording, as I don't have the same on mine and my headphones.

[warm carbon]

it's like that on all my setups - i'll try to get a line out recording

[plain quiver]

Did you filtered the 32x sound correctly on the options ?

[warm carbon]

oh probably not since I didn't know that was an option :p

[plain quiver]

We talked in PM and the Youtube video is flawed as possible when comparing to a direct recording of the system.

[warm carbon]

also, no crashes on any of the misters thus far

[plain quiver]

So I need to focus on the changes during that week.

[warm carbon]

Still running good. Gonna let them rest

[plain quiver]

I think I found something.
The changes made to SH7604 on 2025/01/11 had an impact on the core.
The changes made on 2025/01/13 weren't the cause, as I can crash the core 32x with Knuckles - Chaotix if I undo them.
I'm restoring all previous changes to the SH7604 layer by layer; only the changes made on 11/01/2025 remain.

[plain quiver]

Something seems wrong on the BSC module after more tests on the changes dated on 2025/01/11, that should be the root cause of the issue on Chaotix.

[normal rivet]

FWIW, I've now been running Knuckles for 60 mins on the Jan 6 core

[dawn ginkgo]

Any clue about what is causing the slowdowns in Mortal Kombat II? It has been there since the first release of the core.

[plain quiver]

Absolutely not, and I'm not an expert on MKII 32x, it will most probably need some comparative videos & explanations from testers/players.

[woeful goblet]

Sorry for the late reply. 1 hour running Knuckles with this build and everything good until now

[plain quiver]

I think I've stabilized the core for Chaotix, I need @warm carbon tests later.

[woeful goblet]

I am home right now. If you need more testers, please let me know

[plain quiver]

The more, the merrier.

Sent you a PM.

[woeful goblet]

I am on it! Thanks!

[normal rivet]

I can test as well

[plain quiver]

We have enough testers for this time, I will see with srg320 now with our encouraging results.
Thanks anyway for stepping in too @normal rivet, that's very kind of you.

[plain quiver]

More things for srg320 now from me, and on the PC Engine side from dshadoff.

No 3DO core, never.

😏

[fallow dome]

@plain quiver is the king of trolling, he's figured out how to troll while delivering an invaluable community service. No one can match that genius!!!

[plain quiver]

And no ESD issue too. 😉

[drowsy hemlock]

The invaluable community service is saving us from the 3DO, right?

Place your bets Gex: playable on the 3DO core, or the Switch 2 first?

[warm carbon]

how can you be sure?

[plain quiver]

Trust me, I'm an engineer since 250+ years.

That's enough trolling for today, let's get back to serious work.

[warm carbon]

the misters are chaotix-ing

[plain quiver]

Even Chaotix-ing now ?

That's enough Chaotix.

[warm carbon]

oh i will go look

Yup, all still good.

[plain quiver]

So, that's the BSC module.

I leave srg320 taking a look and fix it, that's a sensible part of the SH-2.

[warm carbon]

I’ll keep them going just in case (since I have nothing better to do with them while I cook)

Later I’ll probably walk around on some carpet with no shoes holding the bare PCBs… just to feel alive

[plain quiver]

There are ESD diodes, no risk to destroy the FPGA if you don't touch the GPIO pins with a fork.

Do you want a fork ? 😏

[warm carbon]

Funny you should mention that, I only carry my misters around via fork

[plain quiver]

Without joking around, could you harm an IC with ESD ? Yes.
Would you harm a DE-10 Nano ? Probably not, as there are protection on PCBs and we're manipulating PCBs, not individual ICs.

[warm carbon]

Oh ESD is still absolutely on the table. It’s just so incredibly unlikely. More to the point: when you swap curiosity for hubris you aren’t a helpful troubleshooter.

[plain quiver]

We worked as a team to identify and tracking when the issue began.
This is very satisfying and that deserves a lot of praise.

I'm sure that will be the same on the SNES core.

[warm carbon]

you did the heavy lifting, duder. We just loaded roms

[plain quiver]

Everyone is doing their part, for the greater good.

[chrome moss]

https://tenor.com/view/greater-good-gif-24234628

[plain quiver]

Experimental build, as some parts of the BSC module (fom the Saturn version) were reverted to the 2025-01-11 state.

EDIT : Removed, as it breaks more than it fixes.

[plain quiver]

Darxide seems to be broken with that build...

Kolibri too.

I'm taking the core down and we will need to wait for srg320 one day.

[glass shale]

In srg320 we trust

[glad aurora]

Indeed!! He's making a 3DO core. I'd go through a wall for the guy

[manic ridge]

Easy there Kool Aid

[plain quiver]

Band-aid experimental version.
Fixed Chaotix intro crash after some loops - with some revert code on the SH-2 module (BSC).

I forgot a parameter yesterday, so the revert wasn't complete last time and it crashed some other games after more tests.
Remember - That's just an intermediate version from my end, you must be better to wait srg320 with a proper and definitive fix at a later time.

---

On the other hand, the MegaCD core really needs an update and most likely a rewrite, as I am not up to the task.

[warm carbon]

ehh, SRG can do it. not like he is working on anything else

[fringe zodiac]

Personally, I would rather favor a MegaCD rewrite than a 3DO core

[pine crystal]

I would prefer a core that doesn't exist yet for a more technically impressive system with a much stronger library of titles over a rewrite of an existing core that's been 'good enough' and perfectly usable for years.

[old sierra]

What are the issues with the Mega CD core that require a refactor of the core?

[manic ridge]

Is it even worth a rewrite at this point? There isn't room to fully merge it with Nuked as I understand it, and we definitely don't have room to merge the 3 systems into a tower of power core, so wouldn't it be better to wait for Mi2Ter for a rewrite

I could see swapping out modules for better/more modern versions etc. of course

[warm carbon]

Power Rangers runs slow, you see

[plain quiver]

That's what I tried these last two days; could much better to rewrite the core in fact than taking pieces of puzzle.

[manic ridge]

gotcha! Yeah that's why I mentioned it

[plain quiver]

Spider-Man vs The Kingpin is freezing on subway levels, Dark Wizard is freezing when exiting towns, some slowdowns during FMVs and videos( like the Power rangers, Popful Mail).
Audio stuttering & glitches on several games.
I tried to change the jt12/jt89 & other modules (T80, FX68K) with newer versions, but it didn't changed anything on those issues.

[woeful goblet]

Hope srg320 can take a look at MegaCD core before 3D0

[old sierra]

How extensive a rewrite are we talking? Days/weeks/months?

[chrome moss]

MegaCD has a better library than the 3DO. I get it though, the current core is decent and playable for the MegaCD whereas we have nothing on the 3DO side of things. Getting 3DO gains a lot more than rewriting and fixing up the MegaCD core. I reckon the rewrite is much less work than the 3DO core though.

Hopefully when we get the MR2 we can get a full tower of power core for it. Until then I reckon it’s more likely we’ll see a 3DO core before we see a MegaCD rewrite (unless someone new comes in)

[velvet mural]

I'll bet srg320 could easily add my XE-1AP module to that maze of controller inputs.

[prisma fiber]

Tower of power core on the Mi2STer would be amazing. Is there any news on the successor FPGA?

[warm carbon]

not really - it's up to sorg

[old sierra]

Which cores are missing this that could use it?

Maybe something Zet-sensei or someone else who knows these cores could add if it is straight forward to port over

[velvet mural]

It's easy to add, except that many of these cores have labyrinths of choices when it comes to controller inputs

Let me get a list...

"This joystick was sold in Japan as joystick for FM-Towns, MSX, Sega Megadrive, PC8801/PC9801 series and X68000 computers."

Megadrive (at least 6 games)
Mega-CD (at least 3 games)
32X (at least 2 games)
source : https://segaretro.org/XE-1_AP

I don't have a comprehensive list handy for the other machines, but I'm sure it could be found

Here's a sort-of hearsay list from reddit about X68000 and FM Towns:
https://www.reddit.com/r/SEGAGENESIS/comments/1knkay6/the_analog_xe1_ap_controller_supported_by_11/

Oh, here's a slightly better list including detailed control mechanisms (from MAME, of all places):
https://rants.vastheman.com/2022/12/24/kabutogani/

https://wiki.mamedev.org/index.php?title=Driver:Dempa_Micom_Soft_Analog/Digital_Intelligent_Controller_System

[pine crystal]

Well, MAME is a 'documentation project'. 😏

[velvet mural]

That might be their goal, but there's a lot in there that isn't correct, and isn't documented, and a lot which isn't even in there. Don't think of it in any way as a reference.

[old sierra]

If there aren't tickets in for PC88 and MSX might be worth adding as those cores are being actively worked on

Maybe someone could do x68000 as well

[warm carbon]

Folks who have had static audio issues (or folks who remember reports of those issues): aside from shadow of the beast 2, are there other games I need to test?

[faint onyx]

I tried the US redump version of SotB II. I can't hear any static sounds. Is it later ingame?

Mega CD

[tulip surge]

I think specifically with analog audio out (https://github.com/MiSTer-devel/MegaCD_MiSTer/issues/112)

[warm carbon]

Yeah, specially analog audio out. It’s fine over toslink and hdmi

[faint onyx]

It's fine via Scart RGB to my Sony CRT too.

[tulip surge]

ive got an original mister multisystem if you need anything tested there. meant to be based on old 6.2 analog board
not set up atm, mostly use my digital stack from porkchop

[faint onyx]

So, analog I/0 board revision related?

[tulip surge]

largely reported with the new AV pro 9.2 boards i think

occasionally get ppl reporting other similar issues but I think those might be more build-of-the-core related than IO board type

[warm carbon]

Yeah, 9.2 boards

Specifically, the mister pi board. But I’m not sure if it’s that board that is the problem, or if it’s a problem with 9.2 boards and that one is just the one everyone has

[tulip surge]

#1046941029296779344 message
Scratch that, think was over hdmi

[fringe zodiac]

I guess that just nobody needs a full tower of power. Neither in HW nor in emulation. Funnily the only games that took advantage of the tower of power are a yet another Doom port or crappy FMV games that had even better versions on the 3DO

Doom, Night Trap and Corpse Killer had better versions on the 3DO. That leaves a rare Brazilian localization of Surgical Strike as the only Tower of Power game that we "miss"

[glad aurora]

Tower of Power isn't feasable on Mister anyways.

[fringe zodiac]

It was not needed in the real world and doesn't help being emulated. I guess that nobody will ever feel the need to play a rare Brazilian Port of Surgical Strike.

[glad aurora]

I believe the Doom 32X enhancement fans have done takes advantage of it

I'm sure whenever we see the next gen Mister whenever that happens we will see it.

[fringe zodiac]

Well, that's a need that is created artificially. I don't see the need that Doom32x needs to have CD support added.

And personally I would rather play the 3DO port.

[glad aurora]

I love my 3DO, but the 3DO port is pretty rough.

that frame rate is brutal

[fringe zodiac]

DOS port on the ao486SX

Or Doom 32x Resurrection proper

It's just like FMV games for the NES. Something Frankenstein is always possible but not really retro at all

[glad aurora]

I enjoy seeing what these people are pulling off

[fringe zodiac]

Those are nice experiments but not "retro" hardware that needs preservation.

I wouldn't even support those SNES Frankensteins but I guess that others enjoy that they do.

[glad aurora]

To each their own

[fringe zodiac]

That's for sure

[glad aurora]

I personally love it, and love seeing the new games on old hardware people make because I'd rather play on these old machines than anything new

[fringe zodiac]

I guess it comes down to "Is there a respect for the limits of the system?" for me.

If you write a homebrew that would have worked on a real system, I am interested.

If you feel the need to "widen the hardware" you should have targeted more advanced hardware in my eyes.

[chrome moss]

Doom resurrection works on real hardware

[fringe zodiac]

It even works on just Sega 32x

[chrome moss]

Yup! I agree there are very few reasons to have a full blown tower of power but if preservation is the goal it’s worth it, eventually. And hopefully we’ll see some homebrew that takes advantage of the hardware. MegaCDs scaling is awesome, and you get tons of storage while the 32x gets you all those colors and extra power. I’m not sure you can using the scaling of the MCD and the extra colors of the 32x at the same time, for example, or if the MCD and its scaling would be limited to the original color pallet of the MD

[warm carbon]

@ivory shale I'm digging into this audio issue as soon as some test boards come in this week. Sounds like Keio Flying Squadron, Sonic CD, Shadow of the Beast2, and Robo Aleste are the biggest offenders. Can you think of others? Games in other cores would also be welcome

[manic ridge]

Tower of Power would consolidate everything into one core so I assume that would be easier to keep updated instead of updating 3 cores. Would also support the couple of games that use CD + 32X. Not big reasons, but if some day we have the room for it maybe it would be good

[gritty tide]

Hey all, I reported a while back about this audio garbling issue. I have a DE10-nano, 9.2 board from misterfpga.co.uk, and 128MB SDRAM v2.9 from MisterAddons. The issue seemed to happen if we set vga_mode=rgb and used HDMI video out and 3.5m audio out. Haven’t tried other configurations but I think it’s related to the vga_mode setting

https://github.com/MiSTer-devel/MegaCD_MiSTer/issues/112

https://misterfpga.org/viewtopic.php?t=8792

[old sierra]

As an aside, what are you plugging into the headphone jack?

[gritty tide]

3.5mm jack into Logitech Z200 speakers

[warm carbon]

👀

What games?

[gritty tide]

Shadow of the Beast 2 and Keio Flying Squadron

It seems it doesn't matter if you output analog video or not, the vga_mode=rgb seems to cause it. I can do more testing, I have free time now

[warm carbon]

I am going to dive into this issue either at the end of this week or next (waiting on some boards to arrive so I can test). But the TL;DR is that this has been a "known issue" for a little bit. Right now, the only solution is to get a DAC and use MiniToslink (or use HDMI audio).

The suspicion is that it's a framework issue with the 9.2 board. The hope is that I can find something that is reproducible for sorg to look at

[old sierra]

If this is a bug then it should be fixed, but for your set up I would recommend getting a DAC that has an optical in and go optical out to that and then to your speakers. Even a cheap one will do a better job than the 3.5mm out of the DE-10 nano. Nobody should really be using that unless they have to for some reason.

[warm carbon]

these are the games I'm gonna look at. I wish I could find someone mentioning a GBA game I could test

[gritty tide]

Sure thanks for looking. I forgot to mention I didn't experience it on Parasite Eve but I can test the other games

[warm carbon]

The PSX games seem more tempermental - might be a silicon lottery thing. I definitely had it in shadow of the best 2

it came up last fall shortly after mister pi dropped their first batch

I think that was the first time a bunch of 9.2 boards got into circulation, so it was originally thought to be a mister pi issue but, as you have noted, it's not limited to that board

[gritty tide]

I'm using the 3.5mm out from the new 9.2 I/O board which sounds clean. I think that including 24-bit analog video were the upgrades on those. The garbling doesn't exist if I set vga_mode=svideo. I can test with many combinations if that would be helpful

[warm carbon]

very interesting that VGA Mode is maybe affecting the sound. I will definitely test that

I think compsote_sync being enabled also was a mitigator? I think I read that on reddit

[gritty tide]

Yep I found it odd too. I found it doesn't matter if you output via HDMI or analog video, it seems to be vga_mode=rgb that made it garble every time

But only on those games

[warm carbon]

oh, open one of those games and turn on composite blend in the audio video options of the core - that was another "fix"

[ivory shale]

I was just using headphones at the time myself. While I didn't use them on every core I did try several and SegaCD was the only one that I ran into an issue with. Not sure if this is related but I reacall someone mentioning some MiSTer device (I think it was the Multisystem 2?) re-routing thw traces for the SD so they would not cause interference with the analog signals. Could this be EMI from either the Taki version of the DE-10 or Analog board considering it seems to be effected by what colors and filters are being outputted?

[warm carbon]

Caco is on a de10 and a co.uk 9.2 board, so the plot thickens

[gritty tide]

I'm putting together a spreadsheet with my combinations, give me some time. I did notice in Shadow of the Beast II, with vga_mode=rgb the first level is distored, but if you open the OSD, it goes away, then returns if you close it

Honestly it sounds like the effect of CD skipping or the audio is just out of sync. I'm not a hardware engineer but it sounds like it's in software

[warm carbon]

I actually have a spread sheet in the works.

https://docs.google.com/spreadsheets/u/1/d/1dJt2nJQp6J4pZiBsfKzR-fk3_mbBl6RYHpMyzInGG_Q/htmlview

[gritty tide]

Cool, I experienced it on all the MegaCD games above with vga_mode=rgb but changing it to anything else and the problem goes away. I never experienced it on the PSX games with vga_mode=rgb. I also experience it on my CRT with vga_mode=rgb but with svideo, no issues (compositive video through MisterAddons Y/C encoder)

[glass shale]

Not even with Parasite Eve intro on the PSX core?

[ivory shale]

It's definitely related to the image the MiSTer is currently outputting. I noticed in Keio that what colors were currently on screen had a big effect, as well as any filters being enabled/disabled. As someone else mentioned even opening the OSD affected it. Which makes me wonder if it's actually electronic interference from the video signal. Although why it only seems to happen for SegaCD (at least for me) I don't know. If it is interference then it's possible even the power supply might effect it, if it's 5v or 9-12v over PD. I had a cheap power supply for my Genesis once that caused noise which went away once I managed to find an authentic AC adapter

[warm carbon]

this is suuuuper interesting

[gritty tide]

Nope, I’ve never had issues with that game or PSX games

[glass shale]

That's a common game for testing on the PSX for people having the audio crackling issue via analog

[warm carbon]

I never did either, to be fair. the only game I could 100% reproduce was shadow of the beast (although I hadn't tested Keio Flying Squadron which also seems to be a silver bullet)

[drowsy hemlock]

Sounds like ESD damage to me

[tropic juniper]

Currently playing Lords of Thunder to death... What a blast...

I discovered some kind of "graphic glitch" if you reach the Stage Helado Max Powered.
Its the Ice Stage at the bottom of the map.

It is reproducible with any Armor. You just need to be max powered.

You will notice at the backgropund some "layer clipping" whatever. Im not a expert....

https://youtu.be/lfoBPtAnLQk?t=1267

On the PC Engine it is not. On any other Stage on the Sega CD is no clipping ....

[jade turret]

I see the same on youtube capture from real hardware, it's not a core bug as far as I can tell.

[plain quiver]

I know.

[glass shale]

Core is complete now

[old sierra]

If that is Knuckles Chaotix playable without issues then that is fantastic news

[plain quiver]

I have not seen any issues on the first 3 worlds today + letting the intro loops for an hour.

[normal rivet]

The Mortal Kombat issue is resolved too?

[plain quiver]

No idea so far, I let the persons who know better to judge themselves.

[plain quiver]

Virtua Figher is correct on today's core.

I tried with Barone's video and synchronized with the left side which is the real hardware.

The video stays completely synchronized now.

[warm carbon]

oh shit

I wonder if I can test mortal kombat

[plain quiver]

The Mortal Kombat II intro is also fixed, I can now stay perfectly in sync with Barone's video on the real thing for at least 10 minutes.

[warm carbon]

ooooo

[plain quiver]

I'm waiting 10 more mins before a definitive conclusion.

[woeful goblet]

I am not home right now. Is the new build on update_all?

[plain quiver]

Not at the moment, unstable build only.

[woeful goblet]

Oh, I found it now 🤦🏻‍♂️. Thanks!

[plain quiver]

Perfect sync after 20 mins.

[old sierra]

Is this potentially the last bugs fixed?

[woeful goblet]

There was some report about slowdons in MK II

[warm carbon]

that's what he just tested

we will have to see if there is any variance in game, but the intro loop being synced for 20 minutes is a p good sign

[plain quiver]

I can't test Afterburner II and Space Harrier, as Barone tested it as Super 32x and we don't have that with the core.

[woeful goblet]

Sorry, it´s been a hard day. I should read the posts more carefully

[warm carbon]

no no duder, you're good

if I had a dollar for every thing I misread on discord....

I'm sorry your day has been rough

[plain quiver]

Motocross Championship is running too fast.

[warm carbon]

ah shit, the 32x saw its shadow. 6 more weeks of no 3DO

[old sierra]

Oh well, getting closer

Are there many missing additional polish features? I know of cheats and porting over the XE-1 controller that David did the work for

[plain quiver]

Kolibri is a little bit slow.

Very, very faint.

[dawn ginkgo]

Slowdowns continues with Johnny Cage's Shadow Uppercut and Shadow Kick moves. It's present also on other moments in the game, especially on Dead's Pool Stage.

[compact plover]

Last time I checked, the multitap doesn't work properly. It's implemented but I couldn't get it to work in any of the few games it supports. I created a Github ticket about it about a year ago FYI:
https://github.com/MiSTer-devel/S32X_MiSTer/issues/54

[astral merlin]

interesting! it is instruction latency, memory bandwidth, bus latch timings, or..?

[jade turret]

Can the MegaDrive core directly boot master system games? I ask as I use Wizzo's gamemenu script to create MGL files which I then place in folders to be put on the root of the SD card. I was able to add ".gbc" to the Game Boy part of the script so GB and GBC games are in one folder but when I add ".sms" to MegaDrive the games scan but black screen when trying to boot anything. Sorry if this isn't in the right place for the query!

[old sierra]

Pretty sure you can't play SMS on either Megadrive core, you want to be using the SMS core to play SMS and GG games

[jade turret]

If you go to Console, then boot he MegaDrive core there is the option to boot Master Sytem (.SMS) games.

[pale plover]

Mega Drive core supports Master System games.

[jade turret]

For some more context, this is my main screen with the folders containing MGL files, generated by the games menu script.

I moved the GBC games into the GB games folder, added ".gbc" to the script so all games show in a single directory.

I wanted to do the same with Megarive, move the Master System games into the MegaDrive games folder, name everything accordingly then run the games menu with ".SMS" added to the MegaDrive section so they would all be in one place and all boot with the same core, but it doesn't seem to work in the same way it does for GB.

[manic ridge]

Does it need a bios to load master system?

[jade turret]

Not sure, I'm not knowledgeable enough to know what the core is doing when loading an SMS game. I presumed that as they booted no issue once the core is open they would boot from an MGL too.

Could be the MD core looks for the bios when the core is running but doesn't do the same if directly booted.

[plucky flare]

what's your mgl look like?

[jade turret]

One sec please....

Generated adding ".SMS" to the MD section of the script.

[plucky flare]

you gotta change the index

I think it is index 2

right now you're trying to load it into the bin/gen/md slot

[jade turret]

("MegaDrive", "_Console/MegaDrive", (({".bin", ".gen", ".md", ".sms"}, 1, "f", 1),))

This was the part that I added SMS too, where / how do I change the index? I'm not technically minded, kinda trying to wing it.

[plucky flare]

I dunno, I guess figure out how to do it in that script. you can test if I'm right by modifying an existing mgl and change index="1" to index="2" and see if that loads correctly

[jade turret]

Gotcha, I'm looking at the script not the MGL.

Changing the MGL index worked, which is great, thank you so much. Looks like I have a fun evening of manually changing MGL files ahead of me, at least the library isn't that big!

As always thanks for the responses everyone.

[fickle hemlock]

something like notepad++ can find+replace a phrase in a whole folder full of files for you

[jade turret]

I ended up changing the value in the script then running it again which worked, thanks though!

[warm carbon]

Can folks having analog audio issues test this build and let me know. I don't hear it in any of the games that had it in 20250408 build. Set your mister.ini's vga_mode=rgb if it isn't as that seems to be the most problematic one.

[gritty tide]

Fixed it for me. I tested Keio Flying Squadron intro, Shadow of the Beast II first level, Popful Mail intro, and Sonic CD intro. I thought I could hear faint popping on Sonic CD's second intro but compared to a video on youtube and that's just the way the game sounds

[warm carbon]

yeah, I was running into that exact issue with some of these things

[fallow dome]

I peeeeeeeeeeeeen'd it

[drowsy halo]

Srg320 makes this core?

[fading hare]

I think he only did the 32X and Sega CD cores. Not the Genesis or Mega Drive cores.

[drowsy halo]

those are cool. Lunar was great

[torn dome]

he did the older genny core

nope, that was Sorg

[versed rapids]

https://github.com/MiSTer-devel/MegaDrive_MiSTer/pull/67

[warm carbon]

Paul is making the rounds, man

[old sierra]

Would be ace if he went on to look at the SMS core

[warm carbon]

stop me if you have heard this one...but what if SRG just rewrote SMS/GG/SegaCD instead of....say......3DO

just spitballin here

[fallow dome]

Thanks for reminding me, time to troll #1329170138234097745

[old sierra]

I am still holding out for someone to do a ground up SC-3000/SG-1000 core

[plain quiver]

Related to the last changes from paulb-nl (SMS Codemasters, HSync and cart_cs).

[warm carbon]

anything to focus test?

[plain quiver]

Please try the last version of Bishoujo Super Street Fighter II: Glamor Queen with it.

[frigid summit]

From the tty2oled documentation:

For your Personal Pictures use the folder /media/fat/tty2oled/pics_pri.
Pictures in this folder are used with priority.

Copy the Genesis Picture into that folder, done.

[glad aurora]

Dude thank you so much!

[cursive sedge]

Do you guys think it's possible to add save states to the core just like the snes one?

[velvet mural]

I don't know. I don't think I could do it, but maybe srg320 could. He's got his hands full right now though.

[old sierra]

Hmm, would that not be much more difficult with us using the Nukey implementation now?

[velvet mural]

Probably

Space will also be needed, so if it's tight as it is, then maybe it's more difficult

[faint onyx]

Paulb-nl would probably do it, if doable.

[fading hare]

I wonder how much space the SNES ss implementation took up. I know it was done differently than other ss implementations.

[split stratus]

I’m wondering if Paulb-nl’s HSYNC change finally fixes interlaced video looking a bit weird.

I’ve been meaning to fix that but wasn’t sure how to fix it

[manic ridge]

I read this as NSYNC then I was disappointed

[split stratus]

Haha

[compact plover]

Since Paul is adding the SMS Codemaster mapper to the MegaDrive core, is it recommended to play SMS games on this core? I heard there's a few games that are incompatible right?

[heavy wraith]

In light of the GBA_accuracy core, which is more accurate than the current GBA core, but has no turbo, I am rethinking the naming of the old, superseeded Genesis-core in names.txt. If I remember right, the difference to the Nuked-MD, besides being no longer developed, is that Nuked-MD is more accurate, but has no Turbo?

[tulip surge]

Yeah, turbo and the adaptive option for the composite blend feature are the main reasons some folks use the older genesis core

[warm carbon]

Honestly, I'm not sure which one is more in demand

But the nuked core is definitely the "accuracy" core

[heavy wraith]

Okay, thanks for the input. I will rename the "Genesis (old)" to "Genesis +" with a clarification in the 54-char version of names.txt saying "SEGA Mega Drive + (Deprecated, Turbo, Adaptive Composite Blend, Less Accurate)". The part after the wide gap goes on a second line and is fine to scroll, so I put more in there than can be shown on one line.

The Nuked-MD core will keep it's naming and in the 54-char version get an equal addition: "SEGA Mega Drive (No Turbo, No Adaptive Composite Blend, More Accurate)"

The "+" at least highlights that it has some more features.

[faint onyx]

Just tested the new unstable core from today. The image jumps a bit vertically every 2-3 seconds.

[plain quiver]

Maybe a change from the HSync.

[faint onyx]

Needs a bit finetuning i guess. Can't fix it on my side (using a RT4K).

[warm carbon]

autocrop?

[faint onyx]

Nope

[warm carbon]

weird. I'll check it out when I'm back home

[faint onyx]

It's more than a jittery jump, a little blink too.

https://streamable.com/htqr08

[warm carbon]

oh yeah, that looks sync-y

[old sierra]

That's a very good question, and I don't have an answer to that one. It will probably take someone doing some extensive testing to determine which is actually "better". There are likely quite a few SMS features missing from the Nukey core

[faint onyx]

Funny thing. Loading SMS games is fine though.

[barren plank]

checked the core, did not see anything out of the ordinary on analog or scaled output with Golden Axe 2

[warm carbon]

Might be a DV thing

[barren plank]

but: while looking for the Golden Axe version in your video, I tested the Japan release of Golden Axe - the intro really makes the scaler not happy on my setup

[barren plank]

the picture drops on the scaled output when the scrolling text gets replaced by the fighter animations. This also happens with the stable core - but the old "Genesis" one has no trouble with the intro

(I am using vsync_adjust=1 BTW)

[faint onyx]

The Codemasters mapper support works, but the tested games are not ok with this core. Fantastic Dizzy cuts the top of the image and Micro Machines shows some garbled graphics while the game scrolls.

edit: Even worth with Fantastic Dizzy. It's unplayable.

Ok, tested Golden Axe 1 and 2 with CRT out, there it's fine.

DV1 isn't the issue on the Tink side though. And direct video generally should work fine anyway, i guess

The issue happens with every MD game though. Strange that the Tink is somehow "confused" now.

[faint onyx]

I'm afraid it's really Direct Video related. In normal HDMI mode the image jump is even worse for a short period during the rom loading. But after that it's fine. Not a solution though.

[versed rapids]

Deamon Claw (maybe bad dump) shows this screen error, on Ares it shows the Neofid logo and hangs after the logo.

[plain quiver]

Bad dump.

The mapper used can't let it dump correctly at the moment, seems to be derivative of the SSF2T one.

I'm working on it outside of the project with other people since this morning.

[versed rapids]

Thank you for the information 👍

[pine crystal]

Man... fingers in everything! 😄

[plain quiver]

You will never know.

[vital idol]

Hah, maybe we will see paprium one day after all.

[plain quiver]

Not a littleman.

[elder briar]

woah, this is sick

[fading hare]

Yeah, this one has been in the works for a long time.

[faint onyx]

It's really nice when they translate the real japanese manual too.

[narrow panther]

I went for cart+digital in the kickstarter so I assume they'll send out a ROM at some point. They did with Astebros

[woeful goblet]

I was hoping the SuperBoy 1 (SMS) was supported wth this last build. It would be very cool to play Super Mario on SMS😃

[plain quiver]

For Shining Force II, the noise glitches on the top of the screen is normal behavior of the game.

Confirmed with gameplay footage on a real system.

[split stratus]

Just got back from vacation, the new unstable build of the MegaDrive core jumps vertically for me every few seconds as well. I found out that when it glitches out, it seems that hsync isn't properly ending.

this is right before the glitch, notice the H frequency is 0.45kHz

it should be about 15.7kHz

not entirely sure why it works 'most' of the time but then glitches for a frame every few seconds

[warm carbon]

yeah, @faint onyx reported the same. I think Zet caught it?

[pale plover]

A bad build from the bot maybe?

[plain quiver]

Npe, HSync modification from Paul.

[warm carbon]

paul giveth

[plain quiver]

The RetroTink doesn't like it.

[warm carbon]

paul taketh away

morph doesn’t like it either

[old sierra]

Has the FW been updated?

[split stratus]

yeah I'm on the latest experimental retrotink firmware and I've used other hdmi sources, like the switch and gamecube + gcvideo v3.1

[pale plover]

So it's definitely not an issue specific to the RetroTink 4K

[split stratus]

also the previous unstable megadrive core from before paulb-nl's latest changes works with no jumping

[plain quiver]

Maybe great to leave a message to Paul on the issue log.
I need to go for the moment and can't do it.

[warm carbon]

let me confirm it’s an issue on the morph as well

[faint onyx]

The issue is somehow directly Direct Video related

[warm carbon]

I’m pretty sure it is

[faint onyx]

in normal HDMI mode the jump happens too, but after the rom load it's fine.

After the Sega logo usually the games don't jump anymore

[warm carbon]

yes, happens on the morph too

I‘ll add a note. @faint onyx can I use your footage?

[faint onyx]

Sure.

[warm carbon]

i can’t get it to jump on pure HDMI

[split stratus]

by pure HDMI, do you mean with direct video disabled? I'm using HDMI just via direct video

[warm carbon]

yeah, just hdmi out the back of the mister into a display

but it definitely jumps in DV

on the morph and the tink

[faint onyx]

I meant normal HDMI mode via Tink. Not the Mister directly connected

Just disable Direct Video in the Mister.ini and use the tink. It jumps weirdly at the rom load. But then it's fine.

[warm carbon]

Ahh ok

[split stratus]

Building the megadrive core with different fitter seeds now to see if that helps

[split stratus]

Didn’t seem to help at all unfortunately

[plain quiver]

Same result on my side.

Reverting is okay, but no seeds could help on that matter.

[glass shale]

Is there an issue open for this on GH?

[plain quiver]

Yes.

[cloud otter]

I think that if it's at the end of a vertical blank on the odd pulldown the hs_clean register doesn't get set. I'm going to try adding a check and setting hs_clean to 1 in that case. I'm also currently on day 2 of covid, so this might just be all imaginary anyway.

[cloud otter]

Hiccup doesn't happen on SMS or low res modes (ex: Addam's Family)

[faint onyx]

Indeed. Very interesting. Tried Flashback, it's fine too.

[cloud otter]

At first I thought NTSC with its weird .5 scanline desync. But PAL has the issue, too.

[cloud otter]

507.5/508 are the two 4.7 microsecond points frame-wise for NTSC. But again, this seems to happen in PAL as well, so it's likely nothing to do with that. I just think that the symmetric pulses are easier to sync because of this issue: https://www.hdretrovision.com/jitter

Scalers are probably specifically designed to fix it which might be overcorrecting the already constrained signal Paul has set up? I dunno. There's a lot of possible places to poke.

[cloud inlet]

noticed I now have a genesis + core in my list, what might the difference be in that?

[warm carbon]

@heavy wraith just updated names.txt - it’s the old Genesis core

[split stratus]

Hi, I fixed the sync issues with the latest MegaDrive unstable core but I could use some testing to make sure I didn't break anything

https://github.com/MP2E/MegaDrive_MiSTer/commit/44d522fd583061e9086d08c26754a6857782725f

this is the relevant change

[faint onyx]

I will test it later. Thanks for helping with this.

[split stratus]

I did some more changes and fixed Interlaced video modes looking a bit weird too!

This one in particular needs testing on CRTs. What I did was remove the video_cleaner module. When I last did this, it caused the top few lines of the video to be skewed far to the right, but I think the consistent HSync should fix that issue. Unfortunately, my CRT doesn't show an issue either way so I can't be sure until I get some outside feedback

[faint onyx]

I've tested a few 320x games. Looks good. 😄

[split stratus]

Glad to hear it! Thanks for testing

[faint onyx]

What did the cart_cs signal fix in the first place? Removing this strange vertical zoom/stretch at the rom load?

[split stratus]

cart_cs signal change fixes that Super Street Fighter 2 hack crashing during gameplay, I don’t know of any other games it affected but in theory it could have caused some official games to crash too

[faint onyx]

Ah ok. But now it's smooth via Tink. Rom load and the games too. Great job!

I always wondered why the Nuke core acted so weird, seems like an little "incompatibility" on the Tink side.

[split stratus]

Thanks! I’ll submit the fix to MiSTer soon, just waiting for Paulb-nl’s feedback

Yeah the video signal generated by Nuked MD is pretty weird, especially the sync signals

Sounds like my fix isn’t quite right, paulb- nl said it brings back broken colors on CRTs..

[faint onyx]

The Interlace fix, or the Hsync fix (or both)?

[split stratus]

HSync fix

Interlace fix is probably ok

I guess that hsync does need to be 4.7us for proper composite video colors

Not sure what the proper fix is now though

[faint onyx]

I hope paulb-nl can find the right fix.

[spring lantern]

Unless someone already addressed it somehow, the composite colors are a pre-existing issue.

https://github.com/MiSTer-devel/MegaDrive_MiSTer/issues/60

[split stratus]

It’s what paulb-nl’s hsync fix is meant to address

I think it works, it just also breaks sync for 320 pixel games when using direct video to a scaler

[spring lantern]

ah, my mistake. haven’t had the chance to try it.

[split stratus]

I tried delaying hsync instead of extending it and that seems to work

I’ll post a build soon, needs testing via composite to CRT to see if the colors are still good

[spring lantern]

for what it's worth, both paulb-nl's and yours give me incorrect colors.

the severity changes when i reload the ROM

[split stratus]

Does this one work any better?

if not, I think I'm stumped. But either way paulb-nl will likely figure it out..

[spring lantern]

lemme give it a shot.

i noticed something else worrying. while it doesn't give me extremely bad colors like MegaDrive, the older Genesis core's colors change when I reload a ROM too.

[split stratus]

Hmm that’s odd

[spring lantern]

still all over the place, but the variations aren't as bad as the last builds

lemme try a non-Sega core

i also need to figure out how to get better pictures, because the iPhone likes to mess with stuff too much.

[spring lantern]

Super Famicom seems consistent to my eye

[warm carbon]

there is something with genesis/megadrive. I’m trying to find it but someone asked me about it a little while back

oh wait, it was you me and nate talking about it

[barren plank]

I tested this one with my setup (DE10-nano, old analog board, RGB CRT connected to analog) and Golden Axe 3 (Japan). The intro has some weird transitions, that make the scaler drop the image on hdmi. It also looks a bit weird on analog. With this version, the internal scaler drops fewer frames in the intro. Before, it would drop after the transition from the character animation to the scrolling, and then again maybe half a second later during the scrolling. Now it is much more stable.

I have no original hardware to compare, but the intro is shown without drops on the older "Genesis" core

[velvet mural]

I don't know where these HSYNC durations are coming from - but has somebody measured an original machine's output ? It seems to me that the core should be aiming to replicate that

[split stratus]

Paulb-nl has a new build that appears to work perfectly

https://github.com/user-attachments/files/21040945/MegaDrive_hs_cepix.rbf.zip

I don’t have a means of measuring the original console yet

[faint onyx]

Looks great. No issues on my side. 👍

[bright pivot]

a playable version of paprium has leaked

[plain quiver]

We know (and sorry for the "littleman" lie and some hints some time ago). 😏

[bright pivot]

haha

yeah

[plain quiver]

More YEEEEAH!

Like in the game intro.

[elder briar]

how much of paprium is even using the genesis

i was under the impression that the fpga on the cart was doing most of the heavy lifting

to the point where the console is practically only used for i/o

[bright pivot]

nope the game runs on console, FPGA part is only for PCM sound and copy protection

but seems like protection fails :p

[elder briar]

that's nice to hear. both that it's only used for sound, and that the protection failed

i know there was a lot of controversy surrounding the release of that game

[woeful goblet]

I have a copy and love this game. In my opinion, one of the best beat’n’up ever. So many secrets and stages. The sound is amazing too.

[light mist]

and then you are made aware of the almighty jump trivializing the game

[woeful goblet]

Since it probably won’t be officially released anytime soon, hope the see this leaked version but I couldn’t find it on the wild

[plain quiver]

Let's keep it civil, just the game is working and a version exists.

[woeful goblet]

Yeah, I know and I am very cool with it. Rules are rules. I am very happy that it is out somewhere. Meanwhile, I will keep my Mega SG out of its box and play the cartridge until there’s a Mister compatible version

[elder briar]

wasn't it supposed to come to modern consoles and eventually steam

whatever happened to that

[plain quiver]

Fonzie ran away with the money ?
The first thing for today is that the prices of cartridges are dropping on my contacts

[bright pivot]

Yes still on tracks, he's actually manufacturing in china

he's in china since the end of january, I got the information from a friend of him

and if all goes right we can hope our copies for christmas

[bright pivot]

seems legit, the game is no more "legendary" and everybody now can play paprium v1.0

[plain quiver]

Next stops, Daemon Claw and Earthion.

[glass shale]

Found the Paprium ROM + RetroArch pack. Now just waiting for MiSTer support! 🙂

[bright pivot]

daemon claw doesnt work on mister

[plain quiver]

The RA core have a MP3 decoder added.
I'm reading the source code right now.

[plain quiver]

Daemon Claw is badly dumped, it's a 16Mo ROM chip when I checked the datasheet of it.

There is a Xilink mapper on the cart which is used also for protection.

[glass shale]

Did you find the PR for GenPluxGX that added support to it?

[elder briar]

do we know if earthion has anything special going on in the cart

[glass shale]

There's no cart yet

[plain quiver]

We will know next month.

[glass shale]

Next month is only digital version for modern platforms?

[bright pivot]

Not really the only thing Kushiro says it's they delayed the cartridge to give the bet experience possible on MD

[elder briar]

i imagine since yuzo is an og he wouldn't want too much weird shit going on with the cart

[plain quiver]

Can't say anymore at the moment.

[plain quiver]

The original archive have the full source code with the modifications, half of it is for the sound driver and a MP3 decoder.

Something like that.

[glass shale]

I think the package I got doesn't have the sources :/

It will yes

[plain quiver]

I don't know at all.

[glass shale]

@visual temple should be able to add support to the MegaDrive core in a heartbeat

[versed rapids]

We could have a MP3 player along cd 😅

[glass shale]

Final release of ZPF doesn’t work in the core?

Paprium

[visual temple]

Did someone figure out how it works?

[glass shale]

RetroArch’s GenPlusGX supports it now

Yep

[versed rapids]

It works on the core for zpf

[glass shale]

Think I got a bad dump then 😔

[versed rapids]

It seems MegaCD could not be used to play music maybe it is why mp3 was choose

[old sierra]

What is that format that allows CD audio in Megadrive games, is it MD+? Does that support PCM?

[bright pivot]

It perfectly works, only no sram high score save

[sly zephyr]

lets hope for a core update

[cloud inlet]

I see someone mentioned Paprium, I 'donated' for a cart years ago it seems - no issue taking a copy when it works rom wise

my money was sure spent on strippers or something

[spring lantern]

Damn, didn’t realize there were still people waiting for carts. The YouTube guys were all like “wow! Fonzie sure delivered! Nothing wrong here!”

[earnest coyote]

It would be nice to play the game I bought all those years ago and never received.

How many years ago ? Wasn't it like 2017 or somtething ?

[elder briar]

it was announced in 2012 but didn't come out until like 2020 or something

i'm guessing a majority of those 8 years was spent figuring out the included leather thong

[velvet mural]

But when did he start taking orders

[elder briar]

i think it was 2017 like you mentioned

[plain quiver]

September 16, 2017.
I paid a copy of the game.
And my copy arrived in late 2020.
But most people never received it; only the first people on the waiting list who pre-ordered it on day one.

[woeful goblet]

Got my copy from ebay in 2020

[fading hare]

I would assume the specific Retroarch core for it is Windows only, and wouldn't work on Steam Deck. I'll just have to be patient.

[earnest coyote]

I saw a release with 3 OSes supported

[fading hare]

Still, it's wild that there is finally a way for a wider audience to actually play the game.

[earnest coyote]

I haven't downloaded or tested anything however.

[plain quiver]

It could be side-loaded on Bizhawk.
In fact, it works better and more stable on Bizhawk at the moment from some users' feedback.

The game tends to crash on RA at a specific location.

[light mist]

Sure it was this late?
I got a non descriptive payment receipt from end of april '17

Ok, found a newsletter from MGF
Apr 29, 2017
…

Oh by the way, the EURO Limited Edition of PAPRIUM is already sold out!!!* don’t miss the USA, Japanese and the Grand Stick III Limited Editions! Of course, the Classic Edition is also still available!
…

[cloud inlet]

yeah, never got anything at all.

[cloud inlet]

I have it on my mister and it seems fine

[bright pivot]

You can pass the first scam game?

[glass shale]

Got the good one, thanks!

[glass shale]

He’s talking about ZPF

[bright pivot]

ahhhh

ok :p

[glass shale]

Paprium core wen

[bright pivot]

wen it's ready :p

[glass shale]

Soon™

[drowsy halo]

Ispapriumoutyet.com

I guess it's kind of out

[glass shale]

It looks like the game is crashing at the same spot? Anyone has been able to finish pirated Paprium yet?

[fading hare]

Maybe try this? #1096614378968727652 message

Though I don't know what Bizhawk is. Presumably a Genesis emulator?

[glass shale]

Never heard about it either! Will take a look! Thanks

[hard silo]

MD-MSU

[old sierra]

Yeah that one. Does it support PCM?

[plucky flare]

it's all cd audio, so yes

[finite rapids]

I told everyone I could he was robbing people haha

[pine crystal]

Fight the good fight.

[violet lynx]

Hey, did you guys hear Paprium has been hacked? Where the hell is the Geneis core section so I can check it out??!?!?

[pine crystal]

Nonsense! That game doesn't exist...

[plain quiver]

Group hallucination.

[violet lynx]

Not sue what a Mega Drive is, but I'm going to drive around until I find the damn Genesis discord channel...

[pine crystal]

Umm...

[violet lynx]

😛

[fallow dome]

So once everyone plays Paprium we’ll stop hearing about it, right?

[pine crystal]

It worked for Quest 64...

...or did it? 😏

[warm carbon]

not until the dunk bank is completely emptied

and it sounds like they have built up quite a savings

[pine crystal]

I'm just hoping VGE doesn't start modeling various leathery accessories.

[plain quiver]

Right.

[light mist]

You are just jealous because it flexes more than you

[fallow dome]

didn’t you get bamboozled by Fonzie

Sounds like you got……

flexed on 💪😎

[light mist]

ever got into an arguing loop with your children where they don't make any sense?
Feels like you try to instigate one

[plain quiver]

With a leather thong, for Robby.

[light mist]

robby doesn't even own a hover board

[fallow dome]

Haha I struck a nerve with him, look at him malding

“Bubububu argue with children!”

“finally i can play my $450 copy of Paprium” he thinks while angrily typing responses to me

[light mist]

well, my incapability to argue on that level made me quit the education sector....
But paprium was a proper preorder sub $100

[fallow dome]

so what you’re saying is you’re not that big of a sucker, but still one

[light mist]

it came well packaged and without mold

not like a certain someones thousands 8bit do order

[fallow dome]

Don’t be jealous of my sweet freebie!

I’ll play Paprium with you, it looks cool

[light mist]

sorry, only the proper cart has the port for coolio dlc

unless there are two pins free on snac?

[glass shale]

Testing Paprium via RA on a Mac here and I couldn't get the issues @clear needle mentions on his video.

[plain quiver]

The code was updated.

Some people used an old archive with an incomplete modified core.

[glass shale]

This is what I've got

[plain quiver]

That's the correct one.

PCN used the older version.

[glass shale]

It looks like there's no effect if I select the option to get sound from the FM chip?

It's sounding always like the MP3 files

Wondering if FM sound data is in the ROM otherwise MiSTer core will miss it?

[plain quiver]

The MP3 files are a hack.

The original game doesn't work like that.

[glass shale]

I know, the game streams sound from a DAC (STM32F4)

But the game should also get FM sound? (there's an option for it)

I enable it, but it's still sounding like the high def sound

[plain quiver]

The redirection isn't done on the core at all when I check the code.

[glass shale]

So it's always forcing the sound from the MP3 files, right?

[plain quiver]

Right.

[glass shale]

I wonder what would that represent for the MiSTer core? No sound? Garbage? FM sound from the ROM itself?

Only time will tell

Soon™

[finite rapids]

I can’t wear the thong. Didn’t come in magnum pouch size

[glass shale]

Mine is the thong edition as well. Still sealed! 😏

[pine crystal]

I would hope so!

[violet lynx]

Hey, you're missing a "1," $1450, thank you very much

[inland quail]

If we're lucky the source code will leak so the crashes and bugs can be fixed

[glass shale]

I foresee MiSTer users playing Paprium on their beautiful devices within a month from now

Soon™

[plucky flare]

as soon as someone writes an mp3 decoder?

[fallow dome]

I nominate Zakk!

[glass shale]

I think FM music will be good enough

(Provided the rom has FM data)

[vital idol]

I would imagine it would be turned into an msu-1 image?

[plucky flare]

you'd need to patch the game

[vital idol]

I thought that was the big reveal today? It has been patched enough to run on emulators?

I didn’t dig too deeply

[plain quiver]

No, a RA core was developed and some parts of the audio chip were bypassed with some MP3 recordings.

It runs with some hacks, enough for a custom software emulator core to run it.

[vital idol]

How were the mp3s generated?

[plain quiver]

Decrypted/bruteforced from the banks on a secondary chip.
