gpSP+ not running pokemon roms

[javelinface]

Hey, have a look at this post. That should solve your problem.

Custom D.E.O.T. V2.0+/Clockwork OS v0.5 image - With customised DEOT interface, Kernel 5.7, Optional 1400MHz OC, Debian 10 Buster, Retroarch 1.9.0, Mupen64+ plus more! (Current build: 200903)

I don’t know if anyone has issue with some GBA games on gPSP standalone emulator (I don’t like RetroArch because of its battery and CPU consumption). I had a blank white screen when starting some Pokemon games (FireRed, Ruby). Googling around and found that gPSP requires special configurations for some specific games to run correctly. Copying game_config.txt file from Github repo in gpSP for gameshell alone build to /home/cpi/apps/emulators will resolve this.
