Old NES games were PACKED with glitches and other oddities. It usually meant you had to blow on the cartridge. It happened less with SNES games and in N64 games, they were usually rare, but they were definitely weird.
I remember that Super Mario 64 DS had a boatload of glitches, and I literally got a list of them from a guy on GameFAQs and started trying to execute them all.
