Raspberry Pi OS: RetroPie does not run roms

Lilian3004

For first: yes this topic does exist already. However, there is no fix yet.

I installed RetroPie on top of Raspberry Pi OS with the git clone command using the shell. I used the basic install.

I put the rom files into the home/RetroPie/roms folder, you know .nes files into /rom/nes and so on. So the roms are on the sd card.

When i start emulationstation per command line the games are visible. but once i start a game - no matter which one - he shows me an error message very shortly and then returns to the game list.

The error code is the following:

/opt/retropie/supplementary/runcommand/runcommand.sh: line 423: printf: 60.02 unvalid number

After that i get redirected to the game list.

The line 423 says:

#get refresh rate (stripping Hz, rounded to integer
mode_info[5]="$(LC_NUMERIC=C printf '%.0f\n' $(status[3]::-2))"

I looked into this path /opt/retropie/emulators and noticed there is only Mupen64+ listed.

I opened the latest Log file and it says the following:

Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-gambatte/gambatte_libretro.so --config /opt/retropie/configs/gb/retroarch.cfg "/home/pi/RetroPie/roms/gb/Avenging Spirit.gb" --appendconfig /dev/shm/retroarch.cfg
/opt/retropie/supplementary/runcommand/runcommand.sh: line 1304: /opt/retropie/emulators/retroarch/bin/retroarch: file or directory not found

The line 1304 in the script says (eval part):

else
eval $COMMAND </dev/tty &>>"$LOG"
ret=$?

Does anyone know what the problem is? Is there a configuration error?

Notes: i did not edit the runcommand script. The roms work perfectly on Android and Windows 10

Are you running EmulationStation from the desktop ?
This is not supported on the Pi and it might be the cause for the 1st runcommand error. Run EmulationStation from the console and not from the desktop in this case.

 /opt/retropie/supplementary/runcommand/runcommand.sh: line 1304: /opt/retropie/emulators/retroarch/bin/retroarch: file or directory not found

This looks like the file in question doesn't exist - did the installation completed without errors ?

@mitu i tried both. Neither works. If i remember right he said the package for the nes emulator could not complete

mitu

If i remember right he said the package for the nes emulator could not complete

This means the installation was from source, you don't have a binary install option for the packages ? Are you running an arm64 installation (64 bit) ?

You can try re-installing the retroarch and lr-fceumm (NES emulator) packages and if you get any errors, post the latest log file from $HOME/RetroPie-Setup/logs on pastebin.com.

@mitu i tried to reinstall RetroArch, it failed. I reinstalled RetroPie completely now and now it seems to work, but once i try a game the game seems to have small graphic issues. I dont know where they come from though. The Raspy 4 should have enough power to run Snes9x flawless.
