A new Easter Egg has been discovered for iOS and the iPhone that is based on the Konami Code. The latter is a sequence of controller button presses that was created as a cheat by games developer Kazuhisa Hashimoto, who used to work for Konami. Hashimoto died last year at the age of 79 and one of the games he worked on was Gradius.
Back in 2003, Hashimoto said that he created the code to make it easier for him to play-test the game. Another game called Contra gave 30 extra lives to those who used the Konami Code on their controller when the title screen appeared. Keep in mind that the code also worked with non-NES games. On the PlayStation, the code would be Up, Up, Down, Down, Left, Right, Left, Right, O, X.
