My stuff:

  • ArchLinux KDE, amdgpu, vulkan, wayland
  • RetroArch installed from official repos
  • cores installed via RetroArch utility

I’m using this command but it results in a graphical glitch when launched from steam:

retroarch -L "path/to/core" "path/to/game"

Possible causes I found:

  • the command may not work if the game is a .cue file
  • loading a game from Steam via RetroArch 64bit can be a problem(?)
  • cores installed with the utility are in “.info” and not in the “.so” extension

I haven’t tried Steam Rom Manager as it doesn’t solve my doubt and in any case I’m not sure it can solve the problem even if set correctly.
