For what it is worth, I went back to v0.3 firmware.
Mame still seems to only run some games, so I have to figure that out. Gameboy Advance emulator runs pretty much everything I have for that platform, so that’s cool.
Trying to get my head around where everything is stored and how the configs work, but making progress.
Avoid the v0.21 if you went through the tutorial and modified Retroarch, I think that is where I went wrong.
