@bairdo, yes, that’s what I’m asking for. It’s hard to diagnose without seeing *exactly* what you’re doing. If you don’t have a way to copy/paste the output then maybe take photos of the screen that show the directory contents and exactly what you’re typing.
Also, where did you get the roms? If they’re all coming from the same source it’s quite possible that none of them are compatible b/c they’re mislabled, corrupted, etc.
