Game Genie

Game Genie was terrific. It would let you beat games that you otherwise might not have the skill to beat. As a child in the early 90s this was terrific. You could play through Super Mario Brothers 3 with infinite lives, invincibilty, and a tanooki suit.

This is a picture of the Game Genie with the official code book. You needed the book to know what codes to use. Technically, you could just guess and find codes that actually worked.

Other Platforms

Game genie was developed for other platforms besides the NES. It was developed for SNES, Sega Genesis, Game Gear, and Game Boy. Other devices were created by different companies for newer consoles. These included the Game Shark for the N64.

You can learn more about Game Genie on the Wikipedia page. There is an interesting article about how it actually works on Mental Floss. Apparently it was originally meant to do much more. You can learn more in this article from the AV Club.
