Here is a little section devoted to some cool passwords and stuff that will start you off strong, as well as an Ultimate Password that I myself generated!
Note: These are SPECIAL Passwords. In other words, 2 character passwords that start you with some of the magics, some of the items, 999999 Sen and 100 Medals. Keep that in mind.
RZ: Starts you at Yokan on Level 7 with the Yellow Auraball.
CB: Starts you at Edo City on Level 10 with the Red and Yellow Auraballs, as well as the Arc-De-Travel.
KR: Starts you in Moo on Level 24 with the Submarine and Bigbot.
NR: Starts you in Athletown on Level 29 with all the Auraballs and Grandpolis opened.
FX: Starts you at Cactus Village with the last boss dead. Characters are at Level 33.
These next passwords are weird. They allow you to view the dialogue scenes and stuff like that.
NS: Sound Test
RS: Info Mode: Lets you view the scenes in the game.
TZ: Message Mode: Lets you view all the text in the game.
Finally, here is an image of my ULTIMATE PASSWORD! YAY! This password starts you at Level 50 with every item, the best equipment, all the magic, and the final boss still alive.
