I'm not sure about NES. I imagine maybe some games with odd mappers?Just wondering, on the nes/snes side of things are there any games that don't work Or have issues?
For SNES, what doesnt work is just anything with less common chips like DSP2-4 and such. DSP1, SuperFX, Cx4, SDD-1, SA-1, etc are supported. Besides that, any ExHiROM games. Only 1 or 2 ExHiROM games were officially made, but many hacks use that format (like Crimson Echoes). But ToP has a patch to make it work. Obviously super scope and mouse games arent supported too. 99% of SNES games work fine. At the most very minor issues.
