If you want to know how nice this community is, you only need to browse the github issues of popular software emulators. Thank god we don't see such things here. One example:
"Do you hate to see new open issues reports? Then I highly recommend you to give this feature request a high priority and implement it soon so PCSX-Redux users like me won't open new issues and complain"
For duckstation, stenzek even had to close it 🙈
oh my god
Did he come back or not?
MiSTer community is great 🙂
sorry i don't get that, what do you mean?
He is still active. I talked to him some days ago and he already fixed 2 of the bugs i reported to him with a possible solution
@ivory verge the savestate you added is not the options menu. You reach this menu with select, the options menu with circle
have you ever seen this in the core?
nope, sorry
thought , this is the menu
I run OSD via start+select, I must have accidentally started it , sorry
all fine, just wanted to know. It would have helped with debugging
I will delete this entry
but at least i know now that it's not random
btw: in duckstation it's rock stable, no matter what CD seek/read speed or cpu speed(30%-500%)
that makes me think it's not CD timing
very strange
i'm not very familiar what else the ps2 would need to emulate, so it could break there
will ask around, maybe somebody knows something
Ps2 has the ps1 cpu but not the gpu from what I’ve been told. That’s why there’s the texture smoothing option, since it’s emulated
Unless I’m completely off base on what you mean
I guess literally anything that isn’t cpu could be the root cause
what happens is that the draw command is never send to the gpu. So either DMA(unlikely) or the Data in RAM is wrong. Wrong data in ram would be CPU(unlikely) or CD(unlikely?) so i'm stuck
i currently think there is something that usually triggers when the loading is finished to tell the game it can now draw. But this is just an idea, could be anything else, too
unfortunatly the loading takes very long, easily 50 million cpu cycles, so comparing cpu logs of duckstation and my emulator could take forever. Need a better way to find out
Man what a goose chase. Good luck!
I have to say you’re insight into this stuff is fascinating. Thanks for always explaining the madness that is core development
it already feels not worth the time for what you get 😅
but being closer than a ps2 is a bit of a motivation, haha
Psx core more real than PlayStation 2 😎
I took a quick look at what kinds of issues the ps1 games have on ps2 and it’s a lots of not loading new screens when transitioning/loading and a few broken music playbacks. Don’t know if that helps at all
Sounds like cd controller issues, but I’m no expert. Not many graphical bugs, but some
yes, CD being the most likely of all the unlikely things. Will compare that first
With the last update this issue is improved. I made around 7 loops and I don't reproduce it
https://github.com/MiSTer-devel/PSX_MiSTer/issues/206

It is still runing. It seems fix. If someone could check it to validate it is ok.
I'd love to check it out after work , unfortunately I still have 5 hours left 😛
Wild, the entitlement of some people still baffles me. I've never had to deal with this but if I would I'd probably just say "fuck you, pay me"
I'll be home soon so then I can loop it for a couple of hours
Thank you. It is still running on my side 🙂
It's got good cooling! It's currently on and outputting into the void actually hehe
just kidding my friend 🙂
I got a second DE10 on the way to try another go at the chip lottery
Anyway, yeah, I'll keep it running and hopefully it stays good
I also have two de10 nano, one for testing 🙂
Have had many of these "random hang" bugs in my career, usually we mark them as "Waive - will not fix"....
I'm getting the second one to build a MiSTer for a friend, surprise gift
ah nice!
Then if money allows it next year and the DE10 isn't gone I'll buy one more for a very special custom build
still good ?
yes it doesn't hang on Image Works logo screen.
very nice. Maybe it depended on the longer CD pause command timing. I use the minimum values now that have been measured, before it was slightly shorter(~10%)
nice
Ah neat
Man I'm reaping the benefits of all your hard work FPGAzumSpass - thank you!
Seems to work fine here 🙂
Great I will close the ticket !!!
Nice, just tested Resident Evil 2 with 4x CD Speed and scene transitions now work. Excellent
can you elaborate more on this ? this game works very well without cd speed x4
Until recently I had to set CD speed to auto to get the transitions between doors to work. Else the screen would stay black. Now I can leave the 4x speed enabled for other games to profit from
ok now i understand 😄
4x is still a hack and doesn't necessarily work well with every game
I tested one more game I had problems to get even running with default settings. "Breath of Fire IV uncensored and subbed" used to not work at all and works now just fine. Really really nice
I've run into a number of them
The Klingon translation of resident Evil doesnt work !
oh noooo
If anyone gets Hellnight working lemme know
mostly because its not been written !
At least Mizzurna Falls supposedly works
basic version works ?
I will raise an issue on the Github. My game hasnt been translated to Klingon. You wrote the core so you can do it 🙂
By basic you mean untranslated?
yes
Yeah the translation will at least boot but with wild graphical problems
Makes it look like I turned the scandoubler on
Where can I find a patch for this game ?
This Mizzurna Falls intrigues me, haven't really heard anything about this until now. There are two english patches, which one is recommended ?
cirosan
and remember: Warning: This game has glitches. Even in the untouched Japanese version, it's not the patches fault.
😄
Noice, cirosan it is
Lemme know if you get it going on mister, I think I applied the patch incorrectly somehow
Just get a boot to bios
I´ve played Mizzurna falls just fine, and I think @scenic reef finished the game on the core
its insanely ambitious for a psx game, is what i've heard
Game boots fine for me, whoaa tank controls galore
mizzurna falls is really buggy in general, it's all event based and a lot of those break for varying reasons. you'll likely have to end up using the guide
savestates probably a big help
nope, must've been someone else
i've played like... 2 minutes of it lol
Maybe it was M.Walrus or Fuzz
I found this wacky controller
Anyone looking for one of these?
Another odd one
This will be fun
I never finished it, the game needs a proper map,it tells you to go to certain places at certain times but doesn't tell you where they are lol
Nice hunt 🙂
That odd controller, it's like the banana PS3 controller of its era
The buttons feel good though
I did not get the Sammy one, although it intrigued me
It's ASCII pad
Oh yeah you're right
Then it should be fine too
I mostly bought it because I like weird controllers
I'll try it out tonight!
Also yeah, trains, I've always wanted to play as it seems relaxing
Yeah , i like densha de go
I've got the Densha De Go Plug&Play (which is running a PC/Linux port of the PS2 version of the game) and Densha De Go for PS4 which sadly has no special controller (the switch version got one though) but is still really fun
I'm looking forward to it
Its a little brother controller…. 🤣
Lmao maybe
Omg is that the Shinkansen controller
I think it's just the general train controller
it looks cool
I am actually waiting on a custom Beatmania board
So a PSX one, HMM
Tempting
How much is it?
15-20 bucks?
10 bucks
The PocketStation I bought is actually unused
It still has the battery thingy
Also love how the battery has a PlayStation logo lol
It almost feels like a crime to take out the tab
That's hot
It's not unused actually! Seems to have some horseracing thing on there
Looks like whoever used it just never used the pocket features 🙃
Lol
densha de go!
is the memory card via multitap on SNAC working for anyone on unstable_20221130?
real MCs work fine on the latest stable with this setup, but for some reason they don't get read any more on unstable
I am glad that the core is already so perfect that we need to delve into such topics https://github.com/MiSTer-devel/PSX_MiSTer/issues/211
Hi! I use this wonderful core on a regular basis, but today I came across this tweet: https://twitter.com/jamesfmackenzie/status/1599090577433165824 And then I checked this comparison video made by...
🙂
it's not really helpful. noone can reproduce the images taken there
yes i know
That comparision makes no sense at all... He's comparing apples to oranges in terms of the final image. Rendering underneath could be exactly the same, yet those differences (hell, those are even different frames!) would be there.
I agree total nonsense
But if you ask me, the image on the MiSTer part of that nonsense look WAY better, so there's that XD
it's totally possible there are such differences. It's never been really verified. If someone wants to do that, they should write a test that compares the vram content digital and not the video output
when i see that even these annyoing glitches, which come from polygon borders not fitting together, are correct....this is the worst in accuracy, because the backdrop shines through
accurate jank 🙂
Omg! This one pixel is somehow different, sad very sad ☹️
I can see the problem one says Mister. One says Playstation. How could Robert have missed something so obvious 🙂
there was a snac code change, but I tested multitap and MCs. I just retried 20221130 build, MCs still working for me in bios and the games I tried. (tried sony and third party cards) which game are you trying?
Yes 🤣
♥️
@wooden rose what filter settings are you using, that looks great
Congratulations @wooden rose
Did you finish it with an omnislash or did you wait for it to time out and just let Cloud slash him?
I waited for the timeout haha
One sec, I will take a picture
You won't be able to reproduce it exactly
The bottom shadow mask is a TrashUncle one, in v2, 2x scale folder
Since I am running at 4k, I use 2x scale, but for 1080p you would use 1x scale
The colors are going to be different as I am also running with HDR (hopefully everyone else will have that soon too)
the frames aren't in sync all of the time which could account for some of these differences, for example
i don't think the video comparison is a proper comparison for the person who raised the github issue's point
and the user is deleted lol
i thought this was a new vid from just 1 day ago
PlayStation vs MiSTer FPGA accuracy test. Both remain exactly in sync after 5354 frames delivered.
Both devices are running Ridge Racer in attract mode. The approach is to synchronize on a single frame and run for one full demo cycle.
Both versions run at 59.83Hz. This is expected (PS1 240p runs slightly off 59.94Hz NTSC spec), causing some fr...
oh someone did it again heh
it's the same person who did the original video
i don't think that they were doing that comparison the way the github issue raiser was trying to though
this sort of comparison probably is possible but yeah not like that
I'm just kidding birdy 🙂
oh i know you weren't taking it seriuosly, i was just responding to the video itself being used as an example of inaccuracy in this way by the github user
🍻
Aren’t they out of sync even when comparing between different OG hardware versions?
i believe so yeah
This comparison was just to show how good core is, someone took it for granted and by force wants to prove that core works differently, pointless submission on github
Sounds like their capture card is capturing at the wrong frame rate or they rendered the video at the wrong frame rate.
This is from the video’s description:
Both versions run at 59.83Hz. This is expected (PS1 240p runs slightly off 59.94Hz NTSC spec), causing some frame interpolation (duplicate frames). This occasionally causes the two versions to desynchronize by one frame, but parity is quickly restored.
More unusual is this, real hardware looks to have shadow under the text. This one is fairly consistent;
But that might well be an interpolation artefact too
any game, including the bios
Actually that is very likely considering the shadow follows the movement between frames
other than setting the controller to SNAC-port1, is there an option i need to change for SNAC MCs to work again?
haven't seen this....it's pointless if they will never come back. will close it
yup
no other settings should affect it that I can think of. which memory card are you trying?
If someone else can check MC with snac and multitap I'd appreciate it. I may need to tweak it again 😦
is it an official ps1 memory card or an aftermarket one?
using a standard MC from sony
hrm okay
I can only check without multitap, and PocketStation...
unfortunatly i cannot check right now, don't have my second mister here and my main one doesn't have any IO board...
i only have the SNAX, not blue's SNAC ps1 adapter so my test might not be useful
Which are you trying @azure hatch snac or snax? I have both.
i believe its your original snac adapter design
OK that's what I tested. I have an idea of what to try, I'll send you a special build to test.
got this prior to SNAX's unveiling awhile back https://www.ebay.com/itm/325232750362
what is changed? should be only the select being used from the register now instead of special counter?
yeah that, but also changed one variable from 255 to 173. going to change that back.
@azure hatch you could double check, the change was added in 11/28 build. so you could try 27th build and see if it works there, and breaks in the 28th build
I'm looking at the change out of curiosity - so it waits 173 cycles to read the serial data again?
turns out the MC works on both builds?
i'll go ahead and test the latest unstable to double check if this wasn't just user error
20221203 showing nothing
try 29, there was two builds on 28th and you might have grabbed wrong one?
ah gotcha
it wait's that long from the ack to the next action which eventually makes the next clk happen.
ended up testing 20221128_2155bf (2nd build of that day) and thats where it breaks, with 29th and onward builds persisting in not reading the MC
If you look closely towards the top, you can see most of these images have a large discrepancy. For instance, the image on the left has a Mister logo, while the right is an authentic Playstation logo. FPGA accuracy is improving but as you can see it's not quite there yet.
Indeed 😆

😄
For me mc works fine with the latest build 20221203
Write/read
are you also running the MC through a multitap, or does your adapter have MC slots on its own
My build is still running, it takes about three times as long
I did a whole bunch of tweaking to tighten the timings for 4k - it's still off but less so, which means less weird white pixels in the output
Just tweaks in the compile process ofc, I don't know my HDL very well yet
testing RE like usual, thanks for trying. that's the same setup I tested too, with tap, etc
But i have error in tekken2
I'll try a bunch of games in a bit too, with the PocketStation haha
As well as the ASCII pad (which turns out is quite nice to use)
Was this with multitap?
Yes
I just tried USA, without multitap, that works fine at least
(reminding myself to pick one up next time)
go ahead and see if that helps. I'll try to see if I get the same thing with tekken2 on an old build.
No change here
did tekken2 work on 11/27? or before?
ran the test build and its still not reading the MC sadly, hope its not because i'm using an aftermarket multitap 😅
this was working perfectly prior so hmm
ok thanks it must be another part of the change, I'll try to debug it if I get the same thing with tekken.
Make sure ACK signal is low for at least 6uS
30uS is what is measured from the OG hardware IIRC?
that's real psx in bios
are you visiting Japan?
No I live here
That's awesome. How you shipped from Japan to the states yet? If so, how much does something like that ASCII 5key turntable average around?
I am currently interested in getting a GuitarFreaks set for PS1 and am looking at YAJ but from what I heard, it's not really worth it for ordering individual items because customs and shipping get expensive fast.
I have not shipped stuff to the states yet, though I have something I need to get out soon.
That turntable is around 10 dollars
Shipping can be relatively cheap, but you have to use the normal post offices
It's mostly weight based, the most expensive thing I have shipped was a very heavy tea set, and that was 30 dollars shipping
Customs isn't much of an issue with personal mail as far as I know, though you are still required to list the items inside
It might be different with the US
You can actually order things from Japan using proxies, even bid on Yahoo auctions. Most will also allow you to do batch shipping
I would recommend doing that, and if not that I would recommend just visiting :V
There's a ton of people buying up all kinds of stuff in Japan to resell
I'm looking a proxy right now and haven't pulled the trigger on anything yet. Worried shipping alone will be more than I can financially chew.
It's a little annoying as it drives up the prices but that's to be expected. You can still find good deals in the lesser visited areas
I decided to buy directly from Japan because resellers are doubling their profits and I don't want to encourage that.
Usually they will allow you to calculate an approximation
Add to that the potential customs fee and you're good
Well due to the inflation now is a good time to buy
The sellers might be compensating for that
That's just economy I guess
But usually proxy is a good idea, Yahoo Auctions and Mercari are typically cheaper than stores
Anyway if you have more questions we should head to #913193374234849301
Ok, I'll follow up there once I have further questions, thanks.
Np
Now that I've beaten FF7 again, I feel I kind of understand why it was so influential. I think it's because the game has a lot of untapped potential
Like there's so much worldbuilding yet not so much actual exploration
It was way less dense with content than I remember, so I think naturally people just wanted more
Time to play the remake
Just wanted to give a solid explanation to the difference happening here. as you can see the red channel is half resolution and offset. this is normal for retrotink 5x which samples at 4:2:2 resolution in default mode. meaning all that is being seen here is scaler artifacts. Other then that the core is 100% accurate 🙂
Huh, did not know this, thank you for the clarification!
Guess that makes a lot of sense too when you count the steps in the staircasing
yeah it's clearly half res red
and the dark underline below the "namco" is the full res tone channel underneath
Yeah, that makes sense
Since it's kind of like a cheap blur, and a cheap blur is kind of like a shadow
If I think of it as a shader that is
makes sense
i figured it was just whatever scaler is being used
but didn't know if the person who made the video had a ps1digital or not
It's completely possible a 4:2:2 capture card is also doing some of this weirdness. It would have to be capturing at native res though
Maybe worth putting this in the ticket even if it's closed?
Opening a ticket was funny - OCD can be such a pain to love with - better open a ticket
I’ll do it sure. Just have to get some free time tomorrow
@hallow plinth After our discussion yesterday I figured I'd check the power usage of the MiSTer again. Running PSX adds a measly 0.6W over just the main menu core (8.6W over 8W).
Way lower than I expected
This translates to roughly 0.12a
Anyway hypothetically with a 4200mAh battery you could play for a little under 3 hours
in a 2d situation a stray pixel would be more significant
like if NES had an out of place pixel it means there's a wrong timing somewhere
those are very easy to see and document though
3d is by nature much less deterministic, even in intro sequences and scripted things like that, just based on environmental factors
If there's any randomization then it won't line up, no. I'm also not sure if the PSX had any changes in output in between revisions or not. Typically the math doesn't change, even on PC video cards from different brands you can more or less expect an identical image given identical settings
We made use of that stability in development to automatically check for unintended visual changes
I'm actually fairly surprised the MiSTer core and the real PSX line up so well
That's great
Like looking at the stills of that video, keeping the subsampling and compression artefacts in mind, it looks pretty damn identical at least from a "where are the edges on the screen" perspective
I would have expected very minor differences but there appears to be nothing (outside of color reproduction, which isn't stable usually)
if someones got a ps1digital and too much time on their hands they could do it programmatically even
Yeah, could be cool
it had at least a few notable changes between some revisions, and there is also the very volatile read speed of cd's
True, that can cause delays
My first PSX actually had graphics failure, either the memory or the gte itself
It wouldn't do textured quads anymore
If it even worked at all
at least the first and later gpus have very different timings and therefore will lead to different results for sure. Additionally all models before PSone have different, asynchronous oscillators for cpu and video, so every individual console could behave slightly different. Most likely you will never notice, but one model has more "time"(cpu/gpu clocks) to render 1 frame than the other before vblank IRQ comes. When a game is one the edge, even few additional clock cycles can make a diffference, leading to them not being in sync after some time
Interesting, didn't know that
when the PSX core starts up, does the screen stay blank or in no signal state on your CRT until you pull up the OSD for anyone else?
Nope
super weird
Hey, anyone know if I can play the Justifier light gun games with the Gun Con 2 now? I remember that it didn't work when we got the initial Gun Con 2 compatibility in the core.
Give the latest PSX unstable a try. Make sure it’s at least 11/25 or newer - #test-builds message
I need to be schooled on memory cards (Virtual ones) with this core.
I have two virtual cards pointing to the core mem1 and mem2 slots on my mister. However they are stuffed and I am wondering if this is the way it is, or is there a way to have an unlimited file
Say like on my PSTV
Its reccomended to put each game in its own folder within /games/PSX, then the core will auto create/mount a virtual mem card per game
for multi-disc games put all discs in the same folder so they share the mem card
you can mount the ones you are already using in slot 2 and the auto-created one in slot 1 and use the BIOS mem card manager to move your existing saves over
Thanks Count!!! Now I need a command to create folders for all my CHD’s at once. Have something like that?
basic batch script (will need to fix up multi-disc games manually after): https://almost-a-technocrat.blogspot.com/2018/04/auto-create-folder-based-on-filename.html?m=1
python script with more smarts to handle multi-disc games: https://gist.github.com/bootsector/6f60d2227243e57628a7f3f76b523404
Awesome!!!! Lastly.. do you know the best way to win Powerball? 😂
hahaha 🙂
the core creates the save file based on folder name when the game first tries to read/write to the mem card, normally starting a new game is enough but I think it was mentioned that for some you may need to actually save in the game for it to happen
oh and you need to enable 'automount memory card 1' in the core's settings
Okie! I have to run the batch file real quick to make folders and will brb
Metal Gear looks better than GCN version now IMO. Crazy!!!
yeah I had the texture filter on when playing through MGS recently, works really well 👍
Here another one.. when I play DS enabled games… I cant get the left analog stick to act right. Even when I go in and try to map it, it does not detect left, up and so fourth… just lets me get right in and gets stuck
Hmm, did you configure the controller in main first?
In main?
the main MiSTer menu, before loading a core
No.. but will give that a shot
once its mapped there, load PSX core and map controls there and it should detect the analog sticks
Another thing thats weird is my front port on the usb board worked fine for a long time… but now when i plug in a controller the light turns green then shuts off immediately afterward. All side ports work just fine
Could a system setting or update be jacking around with this?’
dualshocks had a button to enable/disable analog also, many games that support analog wont automatically enable it, you can either map a button for that purpose or theres a button combo you can use (its listed in the PSX core's menu):
DualShock: Switch Digital/Analog mode with mouse/touchpad click or L3+R3+Up/Down or mapable button
not sure on that one, I read the same issue recently but it was likely you asking about it 🙂
Yup.. the touchpad does switch from digital to analog… just got to get that analog working right 👍
mapping in the main menu should let you map the sticks within the core. If not you could try the pad test core to make sure they're picked up there
If you have a game without analog support, you would need to map it specifically (if you want to use the stick). You can do that using the core's button mapping options and by making use of the "alternative mapping" option that it will prompt you for.
it wasnt picking up the analog sticks when mapping within the core either
Oh right, sorry, I should read better (haven't slept much)
tbh i couldn't remember if you have to map the sticks in the core (i think you do), if its not mapped in main first though that's likely the issue 🙂
playing snatcher on megacd atm so cant check
You may be right, yeah
@slender junco on github there is a very good manual , it describes everything you need 🙂 https://github.com/MiSTer-devel/PSX_MiSTer#readme
@tropic stratus There is a demo 'The Phantom Demo' where the first part is not ok (I think normally text will be displayed). I don't know the behavior on real hardware. There is the exe file and also the source code.
It doesn't look amazing but I got myself a multitap to test with
Plus another interesting controller
SNAC follow up from a few days ago:
There was a minor snac code change a week ago, that seems to have broken it for a few people. You wouldn't know unless you tried an unstable build after 11/28.
@azure hatch and @ivory verge both experienced problems like memcard not showing in bios or couldn't save in Tekken 2(pal).
I tested different misters with different io boards and different bios and different MCs but couldn't reproduce the behavior they were getting.
Since there was basically 4 changes to code(3 very minor) I did 4 builds that reverted each change and had them test. And both got the same result the one build fixxed the problem for them.
I think it may be some HW difference affecting things but not sure.
So here's that build that you guys can test out if you were experiencing any weirdness lately.
Thanks to both of them for letting me know, and testing out a bunch of builds
i didn't run on hardware, but it looks the same as on duckstation and mednafen. Maybe i can check later
is the other psx channel gone? if yes, can i find it archived somewhere?
ok thank you !
any new clues about why the SPU IRQ doesn’t always trigger in Alien?
no, i investigated as much as i could. It all makes absolutly sense: the game just don't wants the IRQ to happen, so it can keep you out of this door.
if you really want: the debug submenu has a cheatcode that is called "open sesame"... sorry "trigger spu irq"
@dry drift
Hopping on this thread
Hmm yeah i ve lost my whole history ☹️
🤦♂️
yea, I saw the video -- so funny
was Dylan Cuthbert still at Argonaut when that game was made? it's situations like this when I was worked on FreeSCI and scummvm that I'd start reaching out to original developers on LinkedIn
Uh-oh, was the old channel purged and not archived?
I wonder if there's some implicit bit set that masks/unmasks that IRQ
LOL, I have tens of megabytes of mIRC logs from 1995-1999 or so
the irq would trigger, if the game would not load a sound sample that loops onto itself
maybe something would prevent the load of that sound sample on hardware?
but the chain of events happening is so long, it's very hard to guess which part is wrong
like, the disc is busy reading something else first and the original request is canceled before its enqueued/read?
so I don't see that the single ram got the dual justifier update. Did it?
And did dual guncons already work?
ah
#unstable-nightlies message
was there specifically an issue with justifiers? Or does this also apply to guncons?
I'm still waiting on my PSX SNAC adapter 😛
it's even longer before, as it only happens if you reenter the level(e.g. die) and not if you make it there on first try
justifier had problems and timer used for justifier had problem, so both snac and non-snac justifiers
guncon should be fine for longer already
thanks
so something when reentering the level will change some condition (ram?) that might influence the loading from CD, which will then copy different data to SPU RAM? It's all very hypothetic. All i can say is that the sound data loading from CD to SPU RAM and SPu playback is just working as expected
Anyway, i spend several full days with it already and the time is up. Unless there is some new finding, i will pass on this one and leave it to the workaround
No problem, I appreciate your diligence 🙂 I’m more curious to have the mystery explained than to see the game working flawlessly 😉
has anybody gotten guitar freaks to work with a Guitar Hero controller?
also, if anybody happens to own a beatmania turntable for PS1, it's natively supported if you enable it's configuration.
I'd take a copy. It's a shame it was removed, it had a lot of useful info to be found with a quick search
things i dunno i need till i do 🙂
Yeah, I also often returned to some threads, you could verify something, etc.
Maybe we could chuck it in a google doc or similar and pin a link to it in here?
it's been a year of testing 🙂
it was a very good year
I assume that was by mistake. Otherwise a mod should be fired! 🙃

@tropic stratus should probably have his own Discord server?
I like this server in large part as folks are normally pretty positive so I'll leave it as I'd like a copy/a copy to be available to search
Me too. However losing lots of valuable information or not making them available for general search is a bad move in my opinion. I mean, jotego has his own server and he’s also around. His server is a great source of info for all of his cores.
Robert has several cores that could benefit from a centralized place for documentation or reference
We're re-arranging things, please bear with us and lets not try to stir up strife
At the end of the day we're trying to make the best experience for new users and existing users and strike a balance between giving everything it's proper place and having too many "places"
discord has given us new tools recently to do this, and we're exploring them
your feedback is valuable, and we're listening
it'd be nice if discord let users rearrange the channel list
I agree
Yeah
there's some new features that give you more control over it
there's also the home channel and #browse channel tabs at the top which are beta features
I like everything showing, and disable notifications on every channel/server outside of direct @
maybe it's just me, but I've already gotten used to this new system and I think the open-cores-forum is a neat idea
prob more a discussion for general, or a 'channel discussion channel' 🙂
yeah it works, loosing the old content is the biggest thing imo
I'm sure that can be worked around, and I have no evidence to present but dollars-to-donuts those channels still exist but they've just locked out regular users to stop the confusion between channels and threads
private high level PSX chat :p
so at some level the info still exists
I mean you could have just asked but w/e
I could have, but I have my faith to guide me :p
i did ask for a copy 🙂
i'm not sure i can share the export public, so i will not for now.Let's just wait for the reconstruct to be finished and decide then
You’re of course free to share - it wasn’t any attempt to hide information only to make the test easier
at the current point i'm not interested in hosting a own discord server. The mods are doing a lot of work here and i don't plan to spend my time with administration, sorry, too much additional overhead
if you think it's legally allowed, i will upload it
it's ok, dont want to cause a hassle for anyone
there's no problem sharing a log of a public channel
nothing in it is personal or private
thanks 👍
nostalgic reading that from the top
we're going to make the channels publically visible as archives for the time being
I wish it were possible to just move them into the forum but unfortunately it's not technically possible with discord
I dig the experimentation. I actually like the new forum method.
honestly I'm surprised there's an "available as archive" feature
but at least then it shows up in search so that's cool
is the old mister-cores channel also gone? Maybe it's possible to move archives channels to a subgroup?
I see it, I see the admin magic happening before my eyes
IRC when 🙃
20 years ago
oh, there is a archive, sorry, nevermind
was about to suggest the post you just added, thanks Sent
Wasn’t it 25? 🤔
IRC we would've lost the history ages ago
unless someone was running an archive bot
IRC core when
snake wont, but can anyone explain the significance of 25?
ao486
I was using IRC in the mid 90's, but it's older than that, 20 years ago is just when people last knew what it was
Damn you’re right hahaha
archive section (read only) is there for now - this can be hidden if you prefer not to see it
Find it at the bottom of the channel list
I wish we were truly elitest and required people to access mister FPGA chat through the ao486 core
but then how would people get help with setting up ao486? 🤔
That’s the test to see if you are worthy
this new feature is great
if you want to hide the archived channels from your list
this new option is a great addition !
by the way for open-cores-forum I encourage posts like "saturn compatibility testing" and etc
it gives a user the ability to create a topic that has some visibility (unlike threads)
at least, that's how i'm hoping it will shape up 🙂
I like the new format, the only issues I have are UX with using Discord on mobile but I appreciate the ability to make my own forum topics.
Thanks for doing all this
Discord is listening to our feedback (this server gets new features early for testing) so if you have pain with discord I can pass that along
rearrange channels, option to show everyone in user list when in a forum
'compact view' for channel list
Other sort options and a default visible option are two things I would like
If we had default visible then I think this could be good for news and test builds
would creating a channel layout channel encourage positive or negative discussion I wonder
lets see
My request to Discord guys: being able to create a "shortcut" in the channels list for a forum channel
Let’s discuss it here #1049875594172715059
Shortcuts like this still function for posts
psx archive , thank You @summer sage @dry drift 🤗
That happens even on OG hardware. And. yeah, it happened to me once. So the core is accurate! 😄
oh really... it's a game bug then
Yeah , happens on PSX , confirmed 🙂
@tropic stratus seriously looked into that bug months ago - now I feel bad
no worries, i have spend time way worse in my life than trying to understand old consoles 🙂
strife psx port when
reading through the chat about the server re-organizing. I think you guys would really like Guilded. Discord is so convoluted and the way people try to organize things with the tools Discord has provided is so weird.
Except everybody already has Discord.
Which means the inertia of moving is nigh-impossible to overcome
that's the only setback for migrating over
And I search this place pretty often, they'd lose all of that old content I imagine. 😦
in the event (unlikely to happen) that the MiSTer guys switched to Guilded, you can keep the old info here and only migrate what's needed.
but again it's just an idea. At least Discord is making an effort in copying Guilded's features.
Hopefully it never happens as I won’t install another Discord-like app on my devices 🙃
Well, gotta keep an open mind. TeamSpeak 5 is on the way and it's gonna be decentralized.
@twin walrus [current thing] is better than [old thing that works] so why don't we move to [current thing]?
That's a fair point.
some people refuse to go to discord from IRC
so I created a bridge between servers
yeah, I know of at least two servers that had to do this because the community is so ancient.
it's cool typing from discord and seeing it in irc
and vice versa
some guys refuse to use anything they can't self-host or that isn't FOSS on Linux.
Dammmmmnnn!!! IRC is still going? Now that’s a blast from the past!
yeah - it's actually how we used to operate and collaborate across all continents
it's a standard internet protocol, it will go on forever
Hey, for what it's worth, a while ago I reported having problems with rumble going crazy and also getting sync drops with Dualshock 4. This most certainly had to do with my power supply being too weak. Today I upgraded from a 2A supply to a 4A one, and now all issues are gone.
I use them wireless - just as easy
which irc net is the good one now?
Efnet maybe?
FGC guy I know is doing SoTN Richter speedruns on a hitbox right now lol https://www.twitch.tv/theblacktastic
Please, Alien Resurrection writes to the SPU Bus are 16-bit or 32-bit?
libera.chat is where all of the former freenode refugees went, you might like that as it's where a ton of the FOSS people went all at once, it's also the most popular irc server atm
Playing THPS2 with logitech F310 and doing combo's and landing manuals works ok, but every so fairly often it just doesn't nail it and the combo dies. I wonder if it's the controller or the input response through usb. Able to land 4 million point tricks nonstop on my real ps1.
if you want it that bad, maybe use snac?
i could never play THPS2 with a pad, not back in the days and not today, keyboard works much better for me
It's likely the controller being different, speaking as someone who did some pro-ish gaming in the past on various games. It'll throw you off to change controllers.
Logitech f310 isn't a great gamepad anyways.
i didn't check, why do you ask? the SPU bus itself is always 16 bit, so 32bit writes are split up. But the door problems comes from samples stored via DMA(always 32->16bit conversion)
Get a dual sense.
This. Also different controllers have different deadzones.
So the diagonals can be vastly different from controller to controller. And the d-pads are the same. They can have tighter diagonals from controller to controller
Maybe so. But the latency could be a lot worse, going by this.
4ms is pretty reasonable
I play everything with a ps5 controller via Bluetooth and other than that the connection sometimes completely crashes and the controller has to reconnect (which happens only on the mister and I wish sometime this would change), there are no missing inputs. I bet it's the controller itself
I think it’s your controller. I use Dualsense and it has never lost connection on MiSTer
Or maybe your BT dongle
I had this happen with ps4 and ps5 controllers and I have 4 controllers. I think it is some kind of buffer overflow or something
What bt dongle are you using?
And do you set polling to 1000?
I never could really pinpoint the issue down but I feel like it happens mostly after starting a few different cores without rebooting the mister
Don’t ask where I got it cuz I’ve had it for many years since RPi2 I think
The one I use is rock solid and connects really quick on MiSTer boot
I'm using this one, I guess some people here use this so I would be surprised that only I have issues with it.
Those dongles need to be moved away from the mister. Using an extension cable moves them away and gives them a better ability to connect
It could be that yours is faulty
confirmed 🙂
better yet get one like this
The huge aerial negates the issue
I never lose connection with it
Looks great!
I'm using a pigtail for it. So normally it's fine, before I lost inputs. I guess I will try to get such a long range one and see what it changes 😎
Truth!
When this happens, do you need to replug the BT dongle?
No I just need to wait until the controller turns off and then I can start it again and it will reconnect and work. Also happens in 2 player mode then both controllers stop working, sometimes the last input sticks and the player moves to one side constantly. After restarting the controllers it's always working again
I ordered the ZEXMTE adapter now. It should good that these adapters are not so expensive 😅
It's under half a frame, it's probably not the latency.
the core is simply amazing, it looks beautiful with 4:3 monitors (1600x1200)...it's been a while since i can't stop playing on psx core, it's been my main use in mister for a while.
Just wanted to say Thank You! to Robert and everyone who helped test this core. I just finished Xenogears. I tried it last year on my XStation PSX, but the cutscenes were so damn long, I couldn't do it. With this core and save states, It was such a joy. On to the next game!
which game is this my mind is breaking
might be a Persona
@grand sage @pseudo plinth thank you both 🙂 it's always great to hear when the core is used and you had fun with it.
My younger daughter and i are currently playing Spyro 1 (PAL of course, she is 8 and doesn't understand much english)
It's great to see she enjoys just exploring the world as much as i did as a child
(well, for me it was mario64 and banjo, but still)
@tropic stratus you put us testers out of a job.... hope you're happy
😉 I know I am
I'm really excited about what you have in mind for the future
i will still fix new bugs if they are found, but i'm currently working on a fork of the psx core...cannot tell yet for what purpose 😉
N64 core confirmed !
oh. I think I have an idea
I don't think you can make an N64 core out of a PSX core.. do they both use MIPS?
there are other things that use the PSX chips
Yeah that's what I figured
With the System 11, you could probably remove a lot of stuff that are only needed for the PSX core, perhaps free up enough space to make the system feasible
take out save states, etc
It was a joke !
The CD and memory card system
you can't joke like that here 😅
Someone always seems to get pissed when someone mentions N64 on De10 Nano
because its not possible and has been discussed to death
And clearly you know exactly why.. 😄
Its because Robert cant make an unconnected system into another one. He is so slack
yes N64 uses more or less the same CPU....at about 3x clock speed, double cache size, floating point added and additional opcodes 🙈
Aye caramba
and Rambus ram
the cpu would not care what ram is used fortunatly
Playstation was basically a scaled down SGI machine
SGI. I loved working on my Old Indigo
@tropic stratus whatever it is - I'm sure it'll be good
but if someone would build a n64 cpu, using the psx cpu as a proven base seems reasonable
I'm actually pretty 'sure' what that purpose is 😛
Tetris Grand Master system 😛 eh I mean Namco System 11
but keep us in suspense 😄
it will be no new system, just a boring psx with a special feature that will not even make it ever into the main build
so i bet much less exciting for most here, than for me, sorry 😦
oh - well we all need a black/green/blue playstation
if it works, it might be the version with the racing stripes 😛
hehehe
I do like the idea though. After all, you have a NDS core that's sitting there waiting for a more capable board.
is it link-cable support? i saw you discussing that on the forum
he told us what it isn't and what he can't tell
you do the rest of the axioms yourself 😄
my childhood. I had Mario 64, Banjo Kazooie and Yoshi's Story as my only games for multiple years
lol
people today upset about not having enough games make me a little disgusted inside haha
i was so sad to learn Yoshi was a 2D game at that time. I wanted to explore a world with yoshi 😅
I have to use the Mister favorites or I just keep scrolling through the endless games
But it was still played a good bit. really hard game tbh
Croc didn't fill the need...it is too slow paced and the controls to stiff
When I played Banjo-Tooie for the first time years later, I was in awe haha
you can ride yoshi in mario sunshine
felt like such a big game for the console
The odd thing is wiki's state that the stop-n-swap feature was never complete, but I unlocked the ability to grab the eggs and things in the first game after swapping carts.... I don't think I believe it was completely cut. I never owned an action replay or gameshark and they were my cartridges
was there ever a full 3d yoshi game?
i know there are lots of 2d ones (even with 3d graphics)
i think im getting a 64 everdrive for xmas, looking forward to messing around with romhacks more
to play ps1 games
yeah the one on Wii U and Switch
mix of 2D and 3D like the Mario World/Land franchise
Well, I guess it's more 2D. maybe my brain is remembering wrong lol
i played both. can't remember about the wii u game but on switch you're forced to collect enough stuff to actually progress in the game. that's when i had enough.
yeah... fair
it's not SUPER difficult. i made it to one of the last worlds in the game, the snow world...but i had to go back to levels to collect enough items to get to some of the later worlds and i had enough
like each level has a certain amount of flowers and you need enough of those to make it to the next world. it sucked i thought.
I hadn't gotten that far so I was not aware it got that bad
I generally try to collect everything as I go in a game though... but it's asinine for most people
I want one so bad, it's always been out of my budget though
the X5s were in stock around black friday for ~105, may still be
That correct!
considering cartridges get a lot of wear and tear, and that a lot of games are so far out of reach cost-wise that it doesn't really justify the cost imo (take it what you will. I'm speaking from experience buying some of them), it's a good investment
Plus playing romhacks on original hardware (if they work) is so cool
yeah, im starting from scratch on 64 games and even stuff like mario 64 is pushing $40 bucks now. so 3-4 games and you're at an everdrive
trust me I've been sold on one for as long as I knew about it.. but I can't drop nearly $300 on it
$105 for the x5 $185 for the x7
Granted I somewhat regret not getting a Everdrive sometimes, as some romhacks reportedly work on the Everdrives but not my 64Drive
Not for the reason you'd think though. It's because the romhacks are poorly made, and the Everdrive does some hackish tricks that allows the incorrect functions to work
When they shouldn't
does the x5 require resetting to save?
yes
what a pain in the ass.. and $80 to remedy that
unfortunately, yes.. but the extra cost doesn't just net you that
but a lot of the cost is justified
it has to use completely different memory design to be able to do it, which is much more expensive
X7 also has real time clock for animal forest (animal crossing) and a USB slot for direct-running roms from PC without having to deal with SD card fuckery, as well as debugging tools for developers, and other things you can do with the USB port
not sure if anything exists for N64, but the USB port on the sd2snes allows you to interface with speedrunning software for tracking collectibles and playing 2-player randomizers on console (where it sends the data to the other person)
The roms have to actually integrate support for it though, so you need clever romhacks to support it
Yeah.. all I really care about is to not have to reset. Only one game uses RTC and I'd rather play that game on GC anyway
I do have an sd2snes, but I haven't used it since getting a MiSTer
maybe I can trade my sd2snes for a 64drive x7
Honestly after a while you get used to it. You get up to turn the console off anyway. And keep in mind that the memory stays intact for a second or two (10 seconds if you have an og model). So you can get a smart switch for the power plug and just remote power off/on manually or with Google/Alexa.
It's not like it's any different for the mister in a sense... It becomes muscle memory to open the menu before you ever turn off the mister.
is the fork the zn-2?
https://twitter.com/zhangch93067765/status/1527257299990876160?lang=en
That adapter looks cool.
Does that mean I can continue playing on a real psx if I wanted to?
It's interfacing just like the real console, so yes 🙂
that snak as well?
SNAC. Yes, it has to be to work for this
memery card and controller
It's available on his Ali express store. excellent work. Just keep in mind you will need a short USB 3.0 extension cable (0.5ft preferred, not long) to use it with a non-Retrocastle MiSTer
He has a custom board design that makes the adapter not fit direct into other MiSTer's
Essentially it uses two USB connectors. The blue colored one goes into the SNAC port. The white colored one is simply a passthrough to the side of the PSX addon board so it doesn't cover up one of the USB ports on the RC (RetroCastle) MiSter board (It also provides stability to the board so it doesn't put stress on a single port)
the SNAC USB is the only one needed
Yo I know it’s a super small complaint .. but the fact that the FPS counter gets cutoff on crt drives me nuts ..
Is there any chance at all that it can be properly placed so I can clearly see how many FPS I’m getting with the sweet turbo feature on !
Gosh respect the safe area, damn
Yes, that is what I was getting at.
Thanks for the reply.
I asked 'cause I was reading this document (for other purposes) and then I remembered about this Alien Resurrection issue and thought it could be worth asking:
https://psx-spx.consoledev.net/soundprocessingunitspu/#spu-adpcm-samples
Also, I just raised a ticket about MKII not working. The issue was with the JP Bios file I was using.
I'm really thankful that this core exists. I have the original hardware but dealing with CDs in this day and age isn't really practical and it's not rare to have issues with reading errors, etc.
I'm more of a Sega fan but the PSX is my favorite 5th gen console.
The 24-bit rendering feature greatly reduces the color-banding in PSX Doom, amazing.
I see....well i also read this part of the documentation but i don't know what it really means...the DMA for transmitting samples is always 32bit, so it should hit nearly all games. But even if it's only when accessing with CPU, you would expect to see it somewhere e.g. in the tests i wrote, where i use a lot of 32bit access to the SPU, but i never saw it. I wouldn't be surprised if that was only a side effect where the first 16bit write was already used by the SPU in the first sample, but the next write in the second sample, leading to the testers to believe there was a bug
Thanks for the detailed explanation.
What’s a good PSX game to test 24-bit RGB?
Someone mentioned a specific one here but I can’t find it. Save states welcome 🙂
Silent hill, every racing game
Just an easy way to tell when 18 bit colors are insufficient
in silent hill ingame, 18bit are likely not enough. But the VGA dithering option might help?
pother than that, just use any 24bit FMV
i think ridge racer R4 was the reason i added the 24bit->18bit VGA dithering
but it's way less obvious there than still image with silent hill
Thanks will check r4
Are these the right settings for 24 but RGB over VGA?
I suppose dither could be off
yes the upper dithering should be off
otherwise you already kind of remove the problem of 18bit color by adding the static dither mask
Ah, ok. Thanks
Also, GunCon 3 emitters are now in stock
https://misteraddons.com/collections/parts/products/guncon-accessories?variant=39803690844293
So you want to use a light gun on MiSTer but you’re not sure what you need. Let me help you decide :) The GunCon2 sync breakout board requires csync from an analog IO board or similar. The other HD15/VGA port can either pass through video or be left disconnected. GunCon2 requires a 15kHz CRT. RGBs MiSTer.ini settings:
For MikeS’s cores?
Has anyone had issues with Dave Mirra Freestyle BMX stuttering, then eventually crashing? It can seem random and usually happens during the first or second level of the career mode. I am running it off an external HDD. Not sure if this is the right place to ask about compatibility or bugs
Yeah, I had thought the same. I usually use it as the go to for testing each new release. For me it has always crashed and paused with a constant stutter
Ok so the game has a problem on default settings, Have you tried turning off the "pause when CD slow" option?
Still doing the same thing
Yeah
Latest unstable ?
Lastest stable from GitHub releases
Ahh ok please try unstable core
Will do
There have been so many changes
Just tried with Mister_unstable_20221119_14e6d3 & PSX_unstable_20221209_168f57. It makes it to the second level on the second run with “Pause on Slow”, without it crashes earlier
That is what the crash looks like, sorry about the high pitch CRT
At around 50s is when it crashes
It seems kinda random when it crashes, if you’re testing you might have to play a bit
Yes confirmed @rich vault
It hangs
Old bug returns
@tropic stratus This issue should be reopened
At least for Dave Mirra
So I think I encountered a pretty fatal bug while experimenting with the widescreen hack feature.
I set the widescreen option to 3:2, and at first it was working like normal. But when I booted up Puchi Carat to test 2D elements, the game turned blank and the bios files got corrupted somehow. I can't load up any games now.
For context, I was using the dual RAM December 5th build. The game was in the CHD format, all the turbo and disc speed options were on default.
Okay I'm starting to think it's not the bios files? I just replaced them and nothing is happening.
How would widescreen hack damage anything? 🙂
I don't know! That's why I'm asking.
It's impossible
Well apparently not because the cores are shot.
If you say so
maybe your sd card is starting to fail?
No everything else works fine, it's only the PS1 core. Which makes me think there is a corrupted file.
did you already re-download the core and see if boots? I'm definitely not an expert or anything, but that's a pretty wild failure if it's causing file corruption
Let me try update_all, since I know it will automatically download missing files.
Okay now it works. Really weird...
I'm a bit behind, is December 5th a new test build or the latest one from update_all
It wasn't, the most recent dual RAM build was earlier today.
Which I downloaded manually while I was playing with the files.
ah okay
One more completed on psx-core, Persona: Revelations, with turbo on, 6x CD Speed, and fast-forward active. No problem from beginning to end. It was 42 hours even with all that...
Nice 👍🏻
You got to hear "persona!" shouted over and over and over
Dance Dance Revolution Core?
Tekken Tag Tournament 1
I am replaying persona 5 strikers now
widescreen can indeed lead a game to crash in case it depends on reading back the vram. But it can never damage the bios files on the sdcard, as the core has no access to the sdcard at all. At worst it could corrupt the memcard or savestate
@rich vault that's really unfortunate. mailcty reported the game works fine on version 20221023, maybe you can check so we know if it's a regression or was never gone
I started Persona 5 a few months ago, when I saw that I had 100 to 200 hrs to finish, I stopped because I didn't have that time, then Persona 5 Royal came, seriously Atlus wants to keep me playing for a year only Persona
I have strikers, but as far as I know, you have to play 5 before, is it true that the story is dependent?
Strikers tees off from the good ending of Persona 5 (not Royal, which has a whole extended part after the Vanilla good ending which Strikers does not take into account)
it's definitely a worse experience and spoiler territory if you play Strikers without at least going through P5
okay, that's good to know, I'm going to play P5 first, then Strikers, I leave P5 Royal for 2024, bye guys until 2024, because P5 will take my life in 2023.😂😂🤣
honestly P5R has a lot of quality of life upgrades over vanilla P5, if you can swing getting a copy of P5R, starting there is better imo
I say this as someone who has played through that 100 hour game more times than is ever necessary
both P5 and then P5R
I have, usually Atlus rpgs I buy even before I can play, in Brazil prices jump the original value at launch easily
Atlus and From Software are guaranteed Pre-sales, my wife already knows that whenever I see a trailer she asks is it from Atlus or From software?
Haha nice, well yes in that case P5R is the way to go. Guns are actually useful for one over P5 and some other QoL stuff that just made it a much better play
it's recognizable when you hit the "normal" good end, and then if you did the right things it'll continue into the Royal ending, so playing Strikers after will make sense
Oh thanks, saved me half a year of life.
first success on my fork: psx CPU can run at nearly 70Mhz within timing specs. Still very early version that can barely run some testroms. Still, a good sign for Revolt, Shadowman and also other MIPS based cores, e.g. psx-based arcades running at higher clock 😉
😮
Woah! Psx Arcade???
Tekken 3 Arcade 😍😍😍🤞🤞🤞
I mean system11
i always said, that i will not work on arcades. But if someone wants to use the cpu to do it, they can
Shame but thanks for your work regardless 😁
Hopefully someone like Jotego could take a look into that
what along side the billion different things he already has in the backlog ?
That’s why I said “someone like Jotego”, in addition to the man himself
Someone who specializes in arcade cores
Man I sure do love the turbo feature ..
i wonder if thats enough to get quake2 to 60fps
Its the Aliens Door fix core !
Forget arcade, I want the PokemonMini guy to do the PlayStation Pocket and have it point to the PSX saves folder
I’m kidding of course, while neat it wouldn’t really be “useful”
What would you do next as a totally different core?
I would say have a nice sleep and enjoy his family
GNet confirmed?? /s
I noticed if I don’t use 480i sync for hdmi with the yc core, interlaced stuff is “wobbly” - seems weird it’d impact analog video but I imagine it’s just due to yc being WIP
i will play around with some things for 1-2 months next year and then see what is next. But the psx core has showed me: a lot of work is worth it when you get good games in return, which i never really got with Lynx or Wonderswan.
And hey, even if it isn't loved by most...someone will love it at the end of the day
For me PlayStation is the best console on the world 🙂
Even if it's just one person...you made that one person's world
And that's what really matters 🧡
playstation is the first console i had, the core is really a dream come true
The psx catalog is huge and amazing
I can't imagine anything left to work on with as much pay off
Yeah it’s my favorite console, just an incredibly vast and varied library.
Maybe a tilt at an x86 FPU? 😄
I love the PlayStation more than anyone else here !
I doubt that
Off topic: how good is a Series S for PS2 emulation? Really wanna play some sequels on it after playing the prequels on the PS1 core
I don't think there's another system like the PSX, with such a library, left without an FPGA implementation. NES, GB, Amiga, SNES, MegaDrive, PSX and maybe Saturn are the home systems with the best/wider libraries ever conceived by mankind.
So, even if I have myself dreamed about maybe 3DO, CDi, etc.. there are few good games there, so such an incredible library in return for all your work and time investment is something you won't be getting again anymore, I think. We're simply there already... Not any more "generational" machines you can replicate in FPGA 🙂
All that is left are niche systems. If I were you, I'd consider I have contributed way more than most of the people on the planet to system preservation, and enjoy simply enjoy life without spending another 2-3 years of your life on replicating another machine.
Hey @frail storm 🙂
Hey Vampier! 😉
Ah well, you came for parts for a new monster? XD
romdb is very important for the mappers... very valuable work I must say
Yeah started back in 2004 - recently some SQL structure for corrupted
Will have to redo a lot of testing - 7000 entries
Going to be a lot of fun
I only used it on a SX console but by seeing some videos looks like that it also runs well. I can point you to the xbox homebrew comunity. Just send me a message 🙂
The ps2 emulator got a stand alone version recently that's way better to use.
That's bad... didn't you have a backup of the db? I am not sure I am understanding the problem
yes - there was a backup the the backup from the backup was corrupted already
going to check which one didn't have issues
going to be quite a lot of fun
closest thing might be fixing or starting from scratch on a new 486 core to get better compatibility
thats an immense job
I know
probably longer than the entire PSX core
486 core was kind of automatically generated wasn’t it? Not to diss on its quality, but I got the impression it was kind of a hack that people beat into working well.
I dont think we should be suggesting anything to Robert. He deserves to do what he wants
yeah, it was an emulator auto translated into verilog
Its originally Bochs
Given how complex the 486 is… sometimes I wonder if it’d be easier to make an ISA adapter for the MiSTer and plug a real 486 in and let the MiSTer do everything else.
of course he will do what he wants, but there's only so much to do left and very few things that would bring the same sort of benefit as the PSX
and working on ao486 is something he has already done in the past
486 is on the borders of when a FPGA implementation becomes less important
VGA & Sound on 486 are the weird parts. Not even real 486 systems had anything approaching standard.
yes so many different soundcards
Makes me happy that most MB these days have a decent enough cards built in
Seriously - it’d be neat to have a MiSTer on an ISA card and it just handled… everything but the cpu.
it's funny how long sound cards sucked on PC
I had a AWE32
but then I only moved to a PC after the AMiga died so I went straight to a 486 DX2 66
I had an SB16 then a GUS then an SBLive
same
Then … whatever was on the motherboard I guess? No longer had to care.
then I got a Pentium 90 like a year an a half later
annoyed me that the PC had a 15 pin joystick all my amiga sticks didnt work
yep I went to a Pentium 120 to play Magic carpet
Gravis Gamepad for life except in retrospect it kinda sucked
I had to fit a heatsink !
Coming from an Amiga and going to a 486 was like a downgrade, sidegrade and upgrade all at the same time
yes
Losing a multi tasking WB was a pain
Doom called though and the Amiga couldnt compete
I look forward to anyone willing to work on some zn-2 cores
(or a romhack for tetris psx that saves to memory card)
Interesting
Cathode Ray Dude approves
Scooped this a few months ago, even had the dumb joystick that screws into the dpad lol
@tropic stratus what are you running that on?
What do we have to sacrifice to get that?
it's not switchable at runtime, so you need a different core/rbf 😦
So PSXer.rbf
it sacrifices accuracy stuff in the CPU that is not required anyway when running in 2x clock speed mode
no point in being accurate with read latency, when you run everything twice as fast 😅
yes, psx2x.rbf 😉
what video are people talking about?
I'm currently having some fun with a fork of the #MisterFPGA PSX core: running the CPU at double clock rate. That plus some additional cache finally makes some games hit the fps cap. Even Re-Volt(PAL) can nearly hold it now.
Psx fork 🙂
nice
Can't wait to try it out
I wonder what would be the effect on Formula 1 97, which has an option for variable draw distance to preserve the frame rate.
It should draw a lot more of the track with this core.
even the normal turbo mode doesn't seem to make any difference. The game drops below 25fps at the start of the race, but does not reduce the draw distance to keep it high
for me it looks like this feature is doing nothing
Oh, OK.
some more days...i still see GTE bugs in some games, probably due to the communication interface being at 2x clock speed now
but even then, it's great to see 🙂
before:
well yes, it needs to be fixed first 😅
Crazy how a year ago some thought psx was impossible on the de 10 nano .. yet here it is .. soon at twice the speed lol
Woooohhoooo ♥️ great work 👍🏻
shadowman at 30 might almost be a good game
(no)
well, it still drops down to about 15 in some parts, but still better than before(6). It runs about as good as the n64 version now
That almost makes me hope that compatibilty is not that much worse and it can live as something in parallel
compat will be probably as good as running something with turbo now. 2x+turbo might be a stretch for some games, but those that suffer from severe slowdowns usually can manage more speed
PSX2P(erformance) and no one will question a second cor entry...
I agree on that, yes. That's the only system with a massive payback in games and software that's left without a good implementation.
Awww man ! Can’t wait to test !
I mean I actually can wait .. but definitely looking forward to trying it out
Who said psx was impossible on de10?
Some unfaithful!
This is just a lie people keep repeating
In the fifteen times I’ve asked no one has provided a source
Perhaps people had doubts about whether this was possible, but I have never seen such a topic
I can’t think of anyone specifically but I certainly remember people expressing doubt that the de 10 could handle psx or if it could it wouldn’t be perfect ..
And than people assumed it would have to be a dual ram setup only core ..
But nope ..
Provide a source
It’s actually not accurate without dual ram but it turned out no one cared about that accuracy 😛
Those conversations happened several times and you’re just being obtuse to deny it, but that’s par for the course
yeah, it was a big deal that day in February when we found out the core was actually going to work with no major compromises
lol
Then why can’t you provide a source?
Should be easy
Because it aggravates you so much
We always knew PSX was possible. We didn’t know whether dual ram would be required and what would be sacrificed for single ram. Even the author didn’t know.
We made a giant sticky saying we didn’t know.
Personally I am still glad dual ram was possible to make development easier
If we had already reused those pins it would have made that a lot harder
there was still questions on what would be possible with or without dual ram. Robert brings all those points up in that very first video he made
Yes I’m literally saying this
No you’re literally not
You can’t read
With OR Without, please try reading the whole sentence before firing off
Is the implication here that he thought PSX wouldn’t be possible at all even after starting the core? That’s just not true
Enjoy your revisionist history
Enjoy your constant lies
You’re so hilariously anti social
Gentlemen, please ☹️
I just wanted to express how awesome the core is.. I wasn’t expecting some sort of Spanish Inquisition ..
Curious how this new core handles the custom Master Edition of PSX Doom
PlayStation Doom: Master Edition. DoomWiki page by @Dark Pulse Finally, Beta 4 is released NEWS: Fourth Beta Release PSXDOOM BETA 4 [11/16/2022]. NEWS: PSP Beta 4 Release : PSP_PSXDOOM_MASTERED_BETA_4 (397MB). Conversion by @Kroc This version isnt more than a hack of the original PSXDoom game. On...
Overclocking almost gets it there, but sigil still brings it to its knees
Also, not to jump into the fray, but I believe the issue was that we weren't sure if the psx core could run single ram without major issues
So you would say that We always knew PSX was possible. We didn’t know whether dual ram would be required and what would be sacrificed for single ram. Even the author didn’t know.
I would say I understand how a false memory could be triggered and possibly blended with saturn which actually was an unknown at the time
But yeah, for the record, we always knew ps1 was possible back when the old ps1 core was being worked on
Yes Saturn was “probably not” by many of us and is now “probably”
And I thought 32X would be harder than it apparently was
But that was just me
Gonna need a source on that stat.
I mean the fact that a PSX core existed before this one was started might have been a clue
I'm actually pretty glad outrun is coming along finally. With PSX and Saturn pretty much locked in, arcade machines are really the last boundary pushers
I need to continue to fuel my densha de go and tetris the grand master addiction
you need to buy a pocket watch to put in the Densha De Go controller
What about a shot glass with a clock on it?
speaking of which, finally ordered my sanwa parts 🙂
We’ve got TGM1 hack already, all the TGM games use the same hardware so it’s plausible someone could do similar PSX hacks for 2 and 3
1 is basically on similar hardware to a ps1. 2 is on slightly more powerful hardware and 3 is basically running on windows xp.
that's when I bought my de10!
Saturn work would greatly help with getting 2 working on MiSTer though
Ahh,my first pass misled me, I found a better run down of the hardwares for it now
i was not 100% sure i could do it at start, that is right. Especially fitting everything including the savestates
@dry drift now where’s your source showing it was always known for certain?
why is there so much discussion about that, even?
I don’t know anything about save state that’s all him
arcade italia is pretty good for that, I use it to figure out what stick configuration certain machines used
Sent being aggro at a passing comment from someone who was excited about how awesome core is
If anyone else had written the core I’m doubtful there would have been save states
Yep that was my bad .. but now we have a definitive answer and a direct source .. so we can get back to playing some psx!
will do that 🙂 we completed spyro 1 today (well 69% only, but we beat it anyway), next is Klonoa
Spyro 1 is such a great game
I started a file a couple days ago
I found a cheat that turn on flying anywhere and that was a good time
before i submit a ticket for my particular bug, has anyone else played aconcagua on the psx core recently and noticed any sound bugs?
Any core settings different from the default settings?
Is it reproducible?
If yes, can you make a savestate and instructions on how to trigger the bug
Isn't aconcagua a game that got an English translation patch this year?
yup
so it would need to be the original and not the translation patched one
not sure why it's not on romhacking.net it's really short-sighted to just have it uploaded to patreon
oh it is up there
it was just so long ago it was a whole page back
oh nvm, it's still linking to the patreon post lol, because it's a big patch.
