If you goto the Evolution Z option from the main menu, you can equip any character you have with whatever items you have, and afterwards, you can click with password button and get that specific layout code, and you can give it to other people, if they want your character build or whatnot.
Thats really all it is, you cant customize anything else, which sucks, and the passwords are really long and well...stupid..so ultimately the feature is ignored.
