Gimmick / Mr. Gimmick has some bangers, and you can't go wrong with any of the NES Mega Man soundtracks. Kid Dracula I also think deserves some love, that soundtrack is pretty good imo. And if you don't mind extensive use of arps, I just discovered that the NES Asterix soundtrack isn't half bad.
@Embarr i don't think my joke detector is working because this feels fun but very much not simple, that would be one hell of an org if i pulled that off
@DrippingYellow ohh, sunsoft. i already had my eye on fester's quest but i don't think i can recreate that fantastic bass they use, still might end up trying one of these
