I’ve been using Batocera 5.29 for a week and I set it up without issues, themes and other advanced configurations were changed (mostly hotkeys) and no problems so far, everything works.
The only issue I’ve found is that Saturn emulation (yabasanshiro 3.4.2) is glitchy. I tested many games and they run full speed, while others don’t but the one I’m playing runs full speed almost everywhere (Shining the Holy Ark), but that’s not the issue.
What is happening is that in the middle of the gameplay depending on what action I do, the background starts to produce artifacts. Sometimes, they go back to normal after a few commands but most of the time they get worse and worse until they cover all the screen and there’s nothing to do than quitting retroarch and load the game again (I’ve found a little trick that sometimes reverts the artifacts, I need to go forth and back in the Status menu).
If I create a savestate while artifacts are being shown, the game is ruined, as loading the savestate will bring back the artifacts all the time, but if I save normally I can exit retroarch and load the game without artifacts again.
I tested same RetroArch version installed from source in a Linux x86 mini PC I have with the same yabasanshiro version (3.4.2) and the game works correctly, no glitches nor artifacts at all.
I tried to change video settings, placing the resolution to “Original” and lowering the rendering resolution to 640×480 to enjoy the best performance, but it does not change anything. I also tested with stock clock and fast / turbo and same.
Is there anyone with this same issue? I repeat, it only seems to happen on RPi4, but maybe there is something to configurate for it to disappear.
Thank you for your help!
