Raspberry Pi 4B 4GB and the Sega Saturn

Do Multi-Disk games work on Yabansiro / Yabause? I can't see a Disk Control option in the Quick Menu, and I was looking at the Yabause documents and can't see that .m3u is supported.
I know Beetle-Saturn can use .m3u but that emulator runs too poorly on my Pi for that to be of any help.
Thanks! I want to play Panzer Dragoon Saga.
Edit: I am told on Reddit that the game should save at the end of the disk, so the save file should then work on subsequent disks. Maybe renaming will be required but it should work.

is there a way to run STV system games on this?
I assume there's a way due to since the help menu of the install script says "ROM Extensions: .iso .cue .zip .ccd .mds\n\nCopy your Sega Saturn & ST-V roms to $romdir/saturn\n\nCopy the required BIOS file saturn_bios.bin / stvbios.zip to $biosdir/yabasanshiro"

A copy/paste mistake, I believe. Yabasanshiro does not support ST-V.

Install again and its working thanks ! <3

Can anyone verify the updates from sept 8 has made
lr-yabasanshiroslower? Not sure if it's my setup. SFZ3 used to be roughly fullspeed, but now it struggles at around 49-55 fps. Performance almost matcheslr-yabause's. -

Performance almost matcheslr-yabause's.I don't have SFZ3, and it's been a while since I ran a Saturn game so I can't say I see a difference in performance but when running SFA2, I did notice some weird occasional problems drawing to the screen and slowdowns here and there.

I installed this on an image a few weeks ago just fine, now when im trying to install on another fresh build im getting an error saying the shader hack failed to install. Any ideas? something change?
-
@mxstar1 Same here, worked on a previous system from awhile ago. I have tried the link provided by Quicksilver, and pulling the files directly from Github. The patch always fails to apply. I'm still messing around with this on my end, If I find anything I'll let you know.
EDIT Just found this on another thread. Could be the emulator got an update, so the patch won't apply to it anymore. This was 16 days ago.
"Without the patch that was discussed in this topic, lr-yabasanshiro will not work on the Pi4. I'm not sure if it applies cleanly (or at all) to the latest lr-yabasanshiro though." -
Looks like there was an update from less than a day ago. The patch was working a few days ago.
-
@Libation yeah, i was able to install without the patch by editing the lr-yabasanshiro.sh file, but it runs awful i only tried a few games, but the graphics were all messed up.
-
@mxstar1 Are you getting badly garbled graphics? Sometimes the image is impossible to even make out?
I'm having the same issue, yet it seems the patch installed successfully. Not sure how long ago I installed yabasanshiro, maybe two weeks ago.
-
@Zering I'm getting black screens, and/or just single colors showing through. The emulator is/was already very garbled with graphics for a lot of games, but some games look perfect on it. Maybe someone with knowledge will chime in soon. If u want to install it now, you can just forget the folder, add only the .sh file and edit it. Just delete the part near the top that has the hack file mentioned, and it will build without it.
-
@mxstar1 that's what the patch fixed. If you disable it, the emulator isn't going to work.
-
@BuZz Yeah thats what i figured, but i dont know how to edit the patch to work with the newly released emulator, hopefully whoever made the patch can re-release it for this updated emulator. I think it was written by joolswills.
@quicksilver maybe you might know? -
That's me.
I'll check but it worked a few days ago. The performance issues are due to compiler optimiser changes most likely. Which also actually break virtua racer in game / map gfx.
The optimiser issues are really due to code with undefined behaviour in the source and the way c/c++ is mixed. I mentioned some problems in the other topic afair.
I am not confident of including a module yet until I have had time to address some more issues upstream.
But I'll check/fix up the patch if it's a quick fix.
-
@mxstar1 the patch failed due to a line ending cleanup upstream (which is great as the mixed endings was an issue).
I rebased the patch so it should work again.
The issue I mentioned with virtua racer may still be present. By the looks of code changes the optimiser flags were tweaked for another arm board due to issues, but really the fix is to identify the undefined behaviour/problematic code and fix it so it doesn't behave differently at different optimiser levels.
-
The virtua racer issue I had seen before when lowering optimisation levels. However it's not the cause now and changing them doesn't help unless I revert to an earlier version.
Bisecting is tricky due to the fork having submodules. I will need to bisect, re-adding submodules when hitting a commit from the upstream repo to find out which actual upstream commit (parent to the libretro branch) had the issue so it will take longer. Probably debugging the parent standalone version would work better.
In the meantime I am going to change my branch to use an older version again.
-
Sorry for topic spam. I have reset my branch back to how it was in may (probably shouldn't have squashed my changes as had to use
git reflogto roll back).I force a version from Jul 11th now.
This was before some big merges were made from upstream. Probably improvements for some games but now my test game virtua racer is working again, and due to the issues I mentioned above it's better for now to lock to this version until I have some time to feed some useful reports upstream.
You will need to do a fresh checkout of my branch etc probably.
