Mega Man Zero 3 Cheats For Game Boy Advance

  1. Fight phantom

    On the second last level, go into the first hyperspace portal. Next, while you are riding the platforms, you should find a door. It leads you to 2 disks and a portal.
    When you go into the portal, you will fight phantom from Megaman Zero 1.
