Can't launch any roms

mitu

Can't reproduce the error myself - it installs succesfully on a Debian 11 system.

Did you perform any additional configuration/package installation on the Debian system after installation ? Installed a newer/older gcc package or added extra repositories ?

@mitu no installation is out of the box ! On the 2nd system, it's a debian 11 too and no problem...
i tried to delete all the retropie and try to re-install all. Do you think that's solve the problem ?

No. Try updating the OS before attempting the installation again (apt update && apt upgrade).

@mitu same problem after update/upgrade...
i tried to reinstall the os in 64 bits version. Or another OS.

Which OS is better for retropie (and UltrastarDx) ?

You can retry with a 32bit install again - if you really need 32 bit.

Latest Debian/Ubuntu LTS/other Ubuntu forks are ok. I don't know what's UltrastarDX, so can't advise here.

@mitu Thanks for your help. I'll reinstall debian 11 64 bits version. If the problem persist, it's a Nuc hardware's problem ! Or i can try to install it on my old Odroid C2, but not sure all emulators can run (Game Cube, Dreamcast,psx, ps2, ...)

@mitu I've reinstalled a 64bits debian and retropie is ok. Now i remember why i've installed a 32 bits system !! It's for the ps2 emulator (pcsx2). It can't run with a 64 bits system !!

mitu

Try using the Flatpak install from https://flathub.org/apps/details/net.pcsx2.PCSX2.

@mitu thank you mitu ! it's the 1st time i heared flatpak !! how can i get the config file for pcsx2 ? When i launch ps2, No config found for ps2 (i think it's the file in /opt/retropie/configs)

mitu

Since the emulator is not installed via RetroPie, you need to create the ps2 system manually - see https://retropie.org.uk/docs/Add-a-New-System-in-EmulationStation/. You need to add the folder to es_systems.cfg, provide a list of extensions for the ROMS (or CD images for PS2 I presume) and the command to start the game.

@mitu Thanks for your help ! all is good (i can lauch all emulators). I've just to remap controllers for dreamcast (to quit the emulator), for pcsx2 and N64. Thanks for all mitu !

If someone install pcsx2 with flatpak, the config file i used to launch it (/opt/retropie/configs/ps2/emulators.cfg) - you have to create the ps2 directory, and the emulators.cfg file

pcsx2 = "flatpak run net.pcsx2.PCSX2 %ROM% --windowed"
pcsx2-nogui = "flatpak run net.pcsx2.PCSX2 %ROM% --fulscreen"
default = "pcsx2-nogui"

And now, i've to read all the forum to optimze retropie !!!!
