Lot of the same things that have already been said were some of my favorites back in the ole 8 bit NES days.
Contra
Megaman series
Super Mario 1&3(didn't really like 2 that much)
Final Fantasy
Metroid
Zelda
Dragon Warrior
Tetris (the original unofficial version with the 2 player option)
TMNT: both the orginal Nintendo and Arcade versions
Wrestlemania
That's all I can think of off the top of my head.
