Equipment out of category
You must be on the world map (not in a town). Press X, then press START, when the menu comes up press these buttons(on your D-pad): Right, Down, Left, Up, Left, Left, Left, Left, Y, Y, Y, Y. This cheat gives you the ability to equip any category character with weapons, armor, helmets etc. out of their category. For example: my yetti now wears a helmet and soldiers scutum. This not only looks cool, but it also increases your stats (dam, hp, pwr, etc.) The only problem with it is that you still cannot equip stuff out of your category. Have fun!
