Rockman and Forte is an excellent game... on the Super Famicom. Its fine enough on the GBA but the music and squished screen real estate doesn't exactly endear it well when its not exactly a forgiving game (that said, to this day I'll never understand why some people think its unplayable with one of the two characters, I forget which... I mean, its not easy clearing the game, but its not impossible either, I've buster only'd it with both on SFC and GBA before, though certain sections did really kick my ass).
Anyway, I really hope those DOS games stay buried. Usually I'd be all "for completion!" but they suck ass, no way round it. Barely playable in places and aside from 3 having a couple of ideas (swimming, later used in MM8, and pretty huge, maze like levels) there's 0 redeeming features.
I'd rather see Wily Tower from RMW ported, or maybe the Power Battle/Fighters games INCLUDING the Neo Geo Pocket Colour port which aside from the lackluster music selection is a pretty interesting port. Maybe do colour versions of the Gameboy games (maybe with a turbo mode to reduce/remove some of the slowdown in later GB games).
