Not that many now that I think of it.

I have 2 copies of Combat for the Atari 2600.

I have Super Mario Bros. for NES on both the 2-in-1 with Duck Hunt and the 3-in-1 with Duck Hunt and World Class Track Meet, as well as Super Mario All-Stars.

I have The Legend of Zelda: Ocarina of Time as the original N64 cart, on the Gamecube as The Legend of Zelda Collector's Edition, again on the Gamecube as Ocarina of Time + Master Quest, and the 3DS remake.
