Up, up, down, down, left, right, left, right, B, A! The Konami Code, or Contra Code as it was often known, is one of the most famous cheat codes in video game history. Although the code first made its appearance in 1986’s Gradius for the NES, it was the punishingly difficult Contra — released two years later — that gave it its fame. 

The Konami Code would give Contra players an extra thirty lives. Given how difficult Contra was, those lives made it possible to survive significantly longer in the game until you got the hang of it. Since that time, the code has become world famous and has seen use in many games.

    Who Created The Konami Code?

    In the early days of gaming, difficulty sliders didn’t exist. When someone created a game, the only way to test it was to master it. If you designed a challenging game, the process of playtesting it became that much more difficult.

    Such was the case with Gradius, a 2D shoot-em-up (or schmup) released on the Nintendo Entertainment System (NES) in 1986. Although originally an arcade game, Konami wanted to bring Gradius to more platforms. One of the playtesters was a man named Kazuhisa Hashimoto, known as the father of the Konami Code.

    Hashimoto programmed the code into Gradius to make testing the game easier. Like Contra, it was known for its extreme difficulty.

    In Gradius, the code would give players every power-up available. The original intent was to remove the code before launch, but it was accidentally left in — and unlike today, you couldn’t patch games back then.

    Developers assumed the code wasn’t left behind by accident. Of course, the code was soon discovered and attained enough acclaim that it was kept in other Konami titles. However, the true popularity of the Konami Code came into effect with the runaway success of Contra.
