Let me repeat my previous question - do you have a system override where the RetroArch settings are different for the gba system ? Is your gba system's configuration file custom/different from the default that RetroPie installs ?

Post the config file (/opt/retropie/configs/gba/retroarch.cfg) on pastebin.com. If you can, get a verbose log from RetroArch during this occurence and post it also on pastebin.com

Some ps1 games are a crashfest on pcsx_rearmed but mostly fixed when using duckstation or swanstation.

If i would use Ipac2 in keyboard mode is this better for the Retropie experience?

Not necessarily.

I choosed the gamepad mode for the configuration under Emulationstation for two players . Because in keyboard mode is only one player input configuration is possible (but Keyboard mode functioning under PPSSPP awesome). I know under Retroarch I have a possibility to configure a second player input too.

Yes, you can configure a 2nd player for a keyboard device, but that can't be done from EmulationStation and you'll need to edit the configuration files (retroarch.cfg). RetroArch expects mostly a gamepad since it started as a console oriented front-end emulator.

I don't really understood configuring inputs under Emulationstation , is this for the standalone emulators or just for the controlling / steering the Emulationstation. Retroarch is for the Libretro emulators input configuration ( I hope this is right ?)

Configuring the inputs in EmulationStation will auto-configure them also for RetroArch and a few other standalone emulators (Mupen64Plus/Daphne/OpenMSX). Any libretro based core should have a configuration ready once you've done it in EmulationStation.

This is getting off-topic here, if you have some more input related questions, I suggest starting a separate topic and reference your posts from here.

Thanks ! Will give it a try and post result after a couple of tests...

Seems your issue is similar to this one, solved with an updated ROM file. I suggest you re-download the game from https://buildbot.libretro.com/assets/cores/Handheld Electronic Game/ and retry.

Perfect, that solved it. Thanks.

Late reply, but confirming...

I wanted and did the same thing with the same result. I switched back to HDMI to composite video and audio converter and the system works well, again.

While testing Scummvm 2.5.0 I bumped into this issue too --- seems to be specific as said here to lr-scummvm's interaction with RetroArch as loading titles explicitly with the non-lr version of ScummVm works.

Not sure exactly when this broke, but my RPi3B downstairs works fine on RetroArch 1.8.8 and my 4B on 1.9.7 doesn't work. Tomorrow I'll try to upgrade my 3B to the latest lr-scummvm just to see if it still works, just because I'm curious.

Anyone else hitting this, and have a way to work around without downgrading? Lr-Scummvm is much better for input. It might be tracked here:

Hello , i have more problems GTA games , Vice City , Burnout dominator and some other i think the most recent PSP games boots fine and menus are ok.
But in the game the graphics are broken and unplayable. Cars and people falling trough the road and grass etc.
Same roms / dvd content are fine on ppsspp win10 desktop machine.

Tried vulkan on the PI4 but more and the same problems, also tried booting retropie standalone image and on twister os same result.

PI4 / 8GB
32 bit or 64bit kernal on twister os same problem.
ppsspp without retropie same problem.
Al on the latest updates of may 2021

Can anyone give some advise.

Ah ok, is there anyway I can reinstall the version that comes with 4.7 to see if it makes a difference?

Since PPSSPP isn't installed on the 4.7 image by default, even if you download the 4.7 image, installing from binary will still get you the current/last version. So, no - you can't reinstall the old version from RetroPie-Setup.

Ah, I never realised that. Sounds like I’m out of luck then.

Thanks

@azurden it’s trivial to acquire mame roms of a certain version, but we can’t assist as per the rules. do not try and find roms and then determine their version after the fact - hundreds of mame rom versions so it will almost certainly be wrong. find the version you need.

Ok, it was my fault:

It was having something to do with my overclocking settings!
I believe maybe something with my voltage, ill use now the default settings.

Since then, no more freezes!

Doing up this great work.
Superb Community, answers after Minutes.

Thanks

I remember seeing a fix for 1. in RetroArch's repository, but don't remember seeing 2. There's a similar issue for 2., that was fixed after 1.8.9, but it looks like it happens with the new graphical widgets.

That's hilarious. I just removed the xboxdrv driver as well as the xpad driver. Both pads working, recognized as XBox 360 controllers. Configured in the menu. Back to the issue where the 8BitDo controller works great, and everything but the D-Pad seems to work on the generic SNES controller.

The package is downloaded from redream.io, which seems to have connectivity problems at the moment, so the package download/query hangs.

@mitu OK thanks
