Gotta second Blaster Master [NES]. Great game, dat one.
As well, Goldeneye 007 [N64], Teenage Mutant Ninja Turtles 1-3 [NES], and Star Wars: Shadows of the Empire [N64]. Especially the code you could preform for Shadows of the Empire, where you basically had to hold down every button at the same time and push the control stick halfway forward with your chin, because you were out of fingers, and hold it for like five seconds.

Shit was intense. They don't make cheat codes like that anymore.

Best cheat code ever

Also, F-Zero X [N64] Because you know a game is awesome when it`s nearly impossible on Normal. Plus, it had a nice metal soundtrack.

So, I forgot lots of games, it seems. Also infiltrator and Ghostbusters for the C64. I just listed the games I/my siblings had when I was a wee kid though.

Edit: Turtles I, II and the gameboy one. Spiderman, Tetris, Mario Land and... uh, yeah, I forget.
