I haven’t used it a whole lot, but heard a lot of good things about RetroArch. The main issue is legally acquiring the ROMs…that’s the part that made me give up lol. From what I understand its a big legal gray area, sounds familiar haha.
There are several public domain games, I was trying to find lists but not having much luck. The games I want to play are like Nintendo sports games and stuff, but not sure where to legally purchase those.
