The Konami Code (Japanese: コナミコマンド, Konami Komando, "Konami command"), also commonly referred to as the Contra Code and sometimes the 30 Lives code, is a cheat code that appears in many Konami video games,[1] as well as some non-Konami games.[2] In the original code, the player has to press the following sequence of buttons on the game controller to enable a cheat or other effects:
↑↑↓↓←→←→BA ; sometimes Start or Select is added to the sequence.
The code has also found a place in popular culture as a reference to the third generation of video game consoles,[3] and is present as an Easter egg on a number of websites.[4][5][6][7][8][9]
