Ever since its inception in 1986, the Konami Code (which is up, up, down, down, left, right, left, right, B, A) may have perhaps helped thousands of gamers. I was able to finish the game Contra because of this code. The Code was created by a man named Kazuhisa Hashimoto during the development of the side-scrolling shooter Gradius, when he discovered it to be too difficult to play during testing.
However, he forgot to remove this bypass and soon, gamers discovered that if you paused Gradius and entered the code, every power-up became theirs. While it was initially considered for removal from the title, developers worried that it could effectively break the game, so it stayed in.
The Konami Code has since then been used in dozens of games, such as Metal Gear Solid, Castlevania, and Dance Dance Revolution.
Hashimoto passed away on February 26, at the age of 79.
Rest in peace, sir. You will always be remembered.
