isn’t there a way to separate the roms from the bios files ? Currently I have all my roms&bios files in the same directory and the filenames don’t help much when it comes to select roms to play. Also it seems that i cannot rename the rom files.
maybe this can help
try to edit ~/.config/retroarch/retroarch.cfg
set system_directory = "~/apps/emulators/bios"
or anywhere you like
also dont forget to
mkdir ~/apps/emulators/bios
