Yu-Gi-Oh! Worldwide Edition: Stairway to the Destined Duel Cheats

Change Your "Target Week" Targets
Eaxmple: So, you got stuck with Kaiba and Yugi to beat? And you're not really in the mood to deal with them? Well, after your targets for "Target Week" are announced, turn off the power on your GBA. This will re-randomize your targets for the week. Keep resetting until you find some duelists you like/can beat (such as Tea and/or Mokuba).
