Best Answer: The Konami Code, known in Japan as the Konami Command (コナミコマンド, Konami Komando?), is a cheat code that appears in many Konami video games,although the code also appears in some non-Konami games. The code was first used in the 1986 release of Gradius for the Nintendo Entertainment System but was made famous in North America in the NES version of Contra, for which it was also dubbed the "30 Lives Code". While pausing the game or during the title screen, the player could press the following sequence of buttons on the game controller: ↑ ↑ ↓ ↓ ← → ← → B A.
