The Origins of the Konami Code Revealed

All together now...

The Konami code is one of the most famous video game cheats of all time, but how did it come about? According to a translated chat between Konami's Kazuhisa Hashimoto and Shigeharu Umezaki, it all started with the NES port of Gradius.

Hashimoto, the code's creator, explains:

I had one guy under me, and he played through the coin-op version. That one’s really tough. I hadn’t played that much and obviously couldn’t beat it myself, so I put in the Konami Code. laughing

Hashimoto's code is legendary now of course, spawning more t-shirts than there are bullets in Gradius. The full interview at GlitterBerri is worth a read.
