Konami code

[Sonia]

Up-Up-Down-Down-Left-Right-Left-Right B, A, Start.

In the 80s, Konami of America and Japan released many games for the Nintendo Entertainment System. Traditionally, programmers would program in hidden cheat codes to help make gameplay easier, which aided especially during late testing periods before commercial launch.

Konami released many popular games on the NES during this era, such as Gradius, Life Force, and Contra. These titles, as well as many subsequent ones, used the same cheat code listed above. Because of its reoccurence, it became known as The Konami Code, and knowing it by heart is one of the trademark signs of a true, old-school gamer.

A common alteration on this code is:
Up-Up-Down-Down-Left-Right-Left-Right, B, A, SELECT, Start.

Many people mentally add in a select in there for one reason only--on the menu screen, pressing select changed the cursor to 2 players instead of 1 player. Contra was always more fun to play with a friend.

The code that every Nintendo nerd had burned into their brain during the late 80s and early 90s. (up-up-down-down-left-right-left-right-B-A-START)

As above (first def), but on newer consoles (read: PS2) the A,B are replaced by X,Circle.

Same as below, but the phrase can also be used figuratively and/or metaphorically.

Very similar to greatest of all arcade games- Street Fighter 2 The World Warrior. However on SF2 its not A B Start buttons but Small punch Med Punch Big Punch.

The Konami Code is a cheat code that appears in many Konami video games, although the code also appears in some non-Konami games. The saying is: Up Up Down Down Left Right Left Right B A Select Start.
