I've got a Zapper and two controllers. I've got one or two TMNT games, Megaman 3 (2?), Super Mario Bros. 1 and 3, Dragon Warrior, Zelda, Duck Hunt, Maniac Mansion, and probably one other.
Though my SNES collection is growing nicely. I've got Super Mario RPG, Yoshi's Island, A Link to the Past, Super Mario World, Dragon Quest 3, 5, 6, Secret of Evermore, Super R-Type, Mother 2, Final Fantasy IV, Secret of Mana, Drakkhen, Super Scope 6, Star Fox, F-Zero, and there's probably one more I missed.
