There is evidence this generator does not work for the X Collection version of the game. It only works for the SNES version.
This password generator is based on Steven Tyber’s crack of one of Mega Man X3’s four password system variations. It is somewhat untested, so some combinations of selections in the form might produce weird or perhaps incorrect results. The JavaScript code behind the generator was programmed by me, but I got some invaluable assistance from MMHP, who let me use her MM2 password generator as model for this one.
