Are there actual converters or do you just mean flashcarts + emulation (or flashcart with GB/GBC dumping ability)?G0523 said:No but you can buy converters online that let you play old GB/GBC games. You just gotta look for them.
It's been a long time since I've tried, but I did play GB stuff using a flashcart and emulator, most of the stuff I threw at it was fine, albeit with some glitching on the borders iirc. GBC stuff for the most part ran pretty slow though, it varied a lot depending on the game (there was a compatibility list somewhere). Basically GB should be solid, while GBC could be a crapshoot.
