I feel gypped. I always thought there was some sort of underlying meaning behind the JUSTIN BAILEY code for the original Metroid on the NES, but I was apparently wrong. According to the Metroid Database :
“…the JUSTIN BAILEY password is a total fluke. If you play around with Metroid‘s password system (something you can do with the Metroid Password Generator program, found in Fan Apps), you can come up with other names and words that work as passwords. The “Justin Bailey” code is one which was found early on and happened to work pretty well, so it became widely reported.”
Still, it does leave the unanswered questions of who originally tried the JUSTIN BAILEY code in the first place and why?
