@jamesatighe This device was designed for GB, GBA, GBC emulation first and foremost. Recently it was cracked wide open and now supports NES, SNES, Genesis, arcade cores, NeoGeo, etc etc. cores. I can say first hand the Nintendo emulation is ... perfect. Amiga, from what I can tell, will support single-disk games like Arkanoid, Pang, Gauntlet II, Rainbow Island, Emerald Mine etc. So for those kinds of games you'd be happy. But I think if you want to play Dungeon Master it's SNES all the way.
