Metroid/Passwords

This page is a collection of unusual codes that you can enter on the password screen of the NES version of Metroid. With the exception of the first code, they are purely coincidental and were not intentionally programmed into the game. Note that the capital letter O has a dot in the middle, while the number 0 does not.
