The Konami Code
The Konami code is a cheat code found in lots of video games beginning with Konami games like Gradius and Contra. It’s also called the Contra Code, Konami Command, or 30 Lives Code.
Wat is the Konami Code? up-up-down-down-left-right-left-right-B-A or sometimes up, up, down, down, left, right, left, right, b, a, enter. In some games it’s start instead of enter. There are lots of variations.
On the PS2 try Up, Up, Down, Down, Left, Right, Left, Right, X, Circle, Start. When in doubt try using the Konami code backwards: A-B-right-left-right-left-down-down-up-up-enter. On cell phones 573 may replace BA.

The list of games that support the Konami Code is quite extensive to say the least. Tell me if you know other interesting Konami code uses.
