I've now managed to get this working with the standard Retropie 4.8 image on a Raspberry Pi 4b!

OP updated with the new instructions!

The full process is quite some work and not tested together with other emulators. Updates to Mesa, SDL and FFmpeg are neccessary for Retropie 4.8.

@sleve_mcdichael this was my understand however; They made a whole lot of changes to the default core for Playstation mainly proper dynarec support. Every game I played that had bugs/slow down have been fixed. Crash team racing is a prime example. Its like they resurrected RaRmEd from the dead or something.

@marzipantz Probably both!

@genos98 Thanks, works perfectly!

@cargorunner said in Playstation - Suddenly stopped working:

@mitu The file has 3 lines, I just listed the one line I changed. The full file from the prebuilt image is...

lr-pcsx-rearmed = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-pcsx-rearmed/pcsx_rearmed_libretro.so --config /opt/retropie/configs/psx/retroarch.cfg %ROM%"
default = "pcsx-rearmed"
pcsx-rearmed = "pushd /opt/retropie/emulators/pcsx-rearmed; ./pcsx -cdfile %ROM%; popd"

this isn't the file from Retropie's prebuilt image. it does not default to pcsx_rearmed (standalone), so not sure what happened here, but good you got it sorted!

@mitu I did indeed configure my controller when I first booted up. Had to re-do it a few times because I was having issues with the blue tooth. I guess I must have mucked something up when I re-configured my controller, because I went back to re-configure my input from the emulationstation ui just to make sure, and now the problem is fixed, I feel like such a dope for not trying this, thanks.

@w1ck3rm4n
There is a naming scheme that the emulator goes by, if you search "retropie psx bios wiki".
You can have all the bios, but the emulator will automatically select from its naming scheme list, the one considered most compatible closest to the top of the list, out of what it can find in the bios folder.

@crush ok, thanks.

@pscotto1234 Thanks for that sharing, the link provided does explain and works around the issue pretty well, I can now enjoy my PI4 as I wished

@mortalwombat said in Any SegaCD/Turbografx-16 fans here? Recommendations welcome:

Never really played the PSP and am a bit skeptical to do so if the Pi already has trouble/can't play the PS2

A pi 4 handles many psp games surprisingly well. Even more performance can be gained by overclocking and setting the display resolution to 720p instead of 1080p via the runcommand menu. Some games will require a little frameskipping and others will be fine without it.

@zering just to be clear you are saying to remap in Emulation Station or Retroarch?

Is there any way to backup my current mapping?

I have a PlayStation 4 Dual Shock controller that seems to not have this issue with the same mapping. The one with the issue is a Vilros classic PlayStation controller with two analog sticks.

@dreamcastkid Deleted what?

It was the games that were converted to .pbp from an iso that were having audio issues. Converting from .bin using PSX2P2P works fine with just the .bin.

This is also happening with RetroArch for Android, reverting to a previous build (november 2020) of PCSX ReARMed solved the issue without changing any RA config.

@mitu thank you very much

@roslof said in What is the best MAME to use with Pi 4 4GB? (Largest library, highest compatability):

I haven't experienced issues with compatible shaders

To summarize, scanlines in vertical games are supposed to be vertical, but because lr-mame & lr-mame2016 are presenting the displayed content as being horizontal, retroarch doesn't know it has to rotate them.
