bwah, none of the retroarch cores manage to load psx games D:
wait, don't I need like a bios???
@Efi yeppums, you do. also certain iso images only work with certain bios (luckily they're usually edge cases) and also the images have to be in *.bin and *.cue formats
@Efi had to look up what that was but no the PS1 retroarch cores do not support PBP :( bin/cue only, as they read the .cue sheets for track timings and music and whatnot.
@Efi oh wait no beetle apparently does, my bad
