The Konami Code was created by Kazuhisa Hashimoto, who was developing the home port of the 1985 arcade game Gradius for the NES.

The code has been used to help non-experts players to progress through the game. The code is also known as the "Contra Code" and "30 Lives Code", since the code provided the player 30 extra lives in Contra. The Konami Code was first used in the release of Gradius (1986), a scrolling shooter for the NES and was popularized among North American players in the NES version of Contra.
