A recently translated developer interview from 2007, courtesy of Shmuplations.com, has revealed that Super Metroid programmer Yasuhiko Fujii (in charge of boss and enemy sprites/hitboxes, etc.) hid a romantic message to his then girlfriend, “Keiko.”

Here’s a quick rundown on the discovery from GameXplain:

Yasuhiko Fujii explains the code he hid in the game:

 

—Were there any scenes in Super Metroid that were your idea(s)?

 

Fujii: Actually, before the fight with Draygon, the boss of Maridia, there’s a group of Evir enemies that do a little “dance”. Their movements actually trace out the letters of a phrase in English, “Keiko Love”! Keiko was the name of a girl I was dating at the time. I was busy with work all the time and couldn’t see her much, so at night while everyone at the office sleeping, I stole a moment and snuck that code in!

 

That little Evir dance wasn’t written in the planning documents anywhere, so I remember my heart beating fast as I coded it, with the worry of it being discovered… but in the end, no one ever found it out. Now isn’t that a romantic story? (laughs)
