Is Yabasanshiro emulator coming on retropie?

BuZz

@grant2258 not sure the point of your post? That vulkan driver is in early stages and is irrelevant.

If you're looking to start another argument I can assure you that isn't going to happen.

grant2258

argument ? Im posting links to a driver related to this not sure where your coming from? I thought this could be good to test on other pies apart from the 4 if your not interested fair enough

Well the driver was never claimed to be completed

Yes, that's exactly what i'm saying, it was released almost 11 months ago and its gpu drivers are still incomplete.

@BuZz what build options are you using? Could you share your scriptmodule?

BuZz

@steeeb Sorry - I wanted to revisit and check some more things before posting . Here you go.

Briefly trying this. The fps is misleading since frameskip is enabled by default so in reality panzer is ~50-55fps. There's a bug with the distance being white. I really wanted to use the crt-pi shader but that drops it to ~45fps. Despite all of these fps drops, the audio does not skip like yabause.

Radiant Silvergun has severe glitches making it unplayable. Sometimes they go away.
Oc'd to 1900Mhz.

@Darksavior Hey! i saw that you were able to get the emulator working. it wont show up on experimental. is there any way to fix this?

Darksavior

@ash0904 It won't show there because it's not done. I added it manually to try it out.

GeekOB

Would love to test this out when it's ready for experimental release @Darksavior.
Will it support CHD or other compressed formats?

Darksavior

@GeekOB All of my games are in chd and they seem to work. If you want to try it out, no one's stopping you. I downloaded the whole repo from https://github.com/joolswills/RetroPie-Setup and took out the installer script and folder with the patch and stuck them in my own RetroPie-Setup folder.

@Darksavior thoses glitches are glitches I can't remove RSG it looked like a texture is backwords, hopefully this fix is better then mines on Castlevania near the start by the mermens it goes black. And minor glitches.
Also set your video settings in retroarch to
Vertical sync, off
hard gpu sync off,
max saw chains images 4
sycn to exact C.F off.

Darksavior

@notthesame No issues with the mermen, other than the black bar on top turning yellow. Attempting to save froze the whole game, though.

Good evening (morning),

Troubleshooting Requested:

I'm very interested in the effort here and completely realize this is incredibly early. I did jump in and attempt to run Yabasanshiro on my RPi4B (everything else in the world is running fine on it, BTW).

I had no trouble compiling/patching/installing with the lr-yabasanshiro module linked above. I copied relevant (and MD5 verified) BIOS files to a /yabasanshiro subfolder within BIOS, as directed by the module help.

Regardless of ROM (CD image) (.chd or cue/bin) I'm getting a black screen and hang. /dev/shm/runcommand.log tails with this:

[INFO] [GL]: VSync => off
[INFO] SET_GEOMETRY: 320x224, aspect: 1.333.
[INFO] [KMS]: New FB: 1920x1080 (stride: 7680).
[INFO] [RCHEEVOS]: Load task finished

There are no significant Errors, Fatals or missing files noted in the log. At this point, I have to kill -9 RetroArch.

These CD images work fine with lr-yabause, so I know the problem is somewhere else on my side. User error, so to speak... (ugh).

Are there any other special dependencies I might be missing? Driver change or upgrade?

GeekOB

I expect gpu to be the main bottleneck for yabansanshiro

steeeb

@BuZz thanks!

Did anyone manage to get the non-LR version to build? As that might offer better frame rates. I've got it to build and it leaves a yabasanshiro.a file that I can't seem to get to play a game - so I think I have the wrong build options.

https://github.com/devmiyax/yabause

Also, Retro Arena paid devmiyax to port it to the XU4 - there module (annoyingly they forked it and "branded" it and won't push anything upstream to here - but it's obvious what the change is) - the repo they point at is just a fork with a libpng fix https://github.com/Retro-Arena/RetroArena-Setup/blob/stable/scriptmodules/emulators/yabause.sh

I think that's probably the best route to get playable games at this time - the input config file looks fairly compatible too plus i think it tries to auto configure inputs if there is no config - devmiyax did have a vulkan branch - no idea how far he got - but when/if pi4 gets decent vulkan drivers that might be the only way a libretro Saturn emulator might be playable for 3D games.

Darksavior

@GeekOB Did you make the folder and transferred the .diff file as noted in the error message? No issues building here.

@roslof My saturn bios is in /home/pi/RetroPie/BIOS/
I use CHD. The compatibility isn't as good as yabause's. Super Tempo did not load for me.
Astal requires the HLE bios for both emulators. It will not load with the real bios.

mechafatnick

Top work all! I'm amazed at how smoothly games like Sega Rally and Fighting Vipers run with it. There's a few graphical artefacts and some effects dont seem to work (the darkness effect in Elevator Action returns for example), but as my saturn has a dead drive i'll definitely take it as a way to get my Virtual On fix :D

Has anyone got any STV games to load? I have the stvy bios in the folder, but it was trying to load it with the normal Saturn bios.

some notes:

-all games loaded from CHD.

-Virtual Fighter remix has a weird bug where a punch can teleport you out of the arena (present in normal yabause - much improved here)

-Virtual on seems to randomly turn to garbage sometimes if you hover on Raiden (works fine other times)

-Quake worked fine in yabasanshiro (enemies didn't appear at all in normal yabause)

-Sky Target has some gibberish down the side of the screen, but crucially it works and is playable :) (the plane didn't even appear on screen in normal yabause)

@steeeb I'm interested in this thread. We've gotten it to build with different options - based on the Retro Arena build scripts - but alas every time we got it to run it returned an EGL error, which made us suspect that we must be missing something obvious at compile time.

I tried even building the non-LR from the LR fork code, yabasanshiro branch, as we know that that one does work on the Pi given the correct compile options, but alas were unsuccessful.

These were the last steps I compiled for myself. I needed to install some of the boost dependencies that were not installed - even though the LR version compiled correctly without them, which is already a telltale sign that I'm probably compiling things that might not be needed:

[clone lr-yabasanshiro per Buzz's script. apply patch]

---- binary goes to build/src/retro_arena/yabasanshiro

@Darksavior I tested some games - mostly Radiant Silvergun, Die Hard Arcade, and a bit of the Sega arcade games - Virtua Racing, Sega Rally, Virtua Cop 2. Virtua Cop 2 will slow down a lot, only run at around 40fps or so.

I'm OC'ed at 2000 and V3D at 750, which does seem to help the most. I have a fan as Saturn emulation on any of the current emulators just gets the temperature to 80 in almost no time, and then it starts throttling. As soon as V3D drops the game starts rendering much slower.

@barbudreadmon you're absolutely right indeed. CPU and V3D seem to be the main bottlenecks here, but to be honest it does run at almost 50-55fps for the most part, which is not bad. Would you have any perspective into what compilation flags are you using to get the correct drivers for the Pi to work? I'd expect that to be at the core level, and not at the libretro layer? Or am I completely off track trying to get it to compile from your fork?

Thanks all and happy Sunday.

roslof

@Darksavior thank you. This is very unusual. I don't typically have issues like this. I would have thought it was related to BIOS, but everything seems to check out. Verbose logging yields nothing of interest. I did learn that removing the BIOS and having the BIOS yield the same results. Nothing in the log(s). Bizarre.

Symptom: With EmulationStation, launching emulator lr-yabasanshiro, the screen remains completely black. No Saturn system boot. No audio. Not a single pixel renders. Then it hangs. Must manually kill retroarch.

BIOS were placed in both ~/BIOS and ~/BIOS/Yabasanshiro:

stvbios.zip
md5: 53a094ad3a188f86de4e64624fe9b3ca

saturn_bios.bin
md5: af5828fdff51384f99b3c4926be27762

I did try several different versions of stvbios.zip, but other sites mentioned the one I posted above should be fine.

I've also tried:

Nuking/rebuilding lr-yabasanshiro
Different BIOS
Different Saturn Disk Images
Different formats (.chd, .cue/.bin)
Latest MESA (which really hasn't changed in months)

Not sure how to troubleshoot beyond this. So odd...
