NES:
Batman 1 had better graphics (and better game overall) than the one on genesis, IMO.
N64:
Zelda Ocarina of Time, so much freedom and scope in this game.
Dreamcast:
Soul Calibur: Some friends used to PSX graphics thought it was CGI and couldn't believe it was in game. This game was a beast, more than Rogue Leader on gamecube. But mainly because of the really bad vaseline effect video cables Nintendo used to ship with their consoles.
