Casper Spirit Dimensions Cheats

In Casper's house, move in front of the bookcase. Shoot it with normal, fire, fire, ice, normal, fire, and super spirit blasts, in that order. A secret room will be revealed. Inside you'll find Lucky the Chicken, who will tell you part of a story.

At the title screen, hold down L1, L2, R1, R2 until you hear a clucking noise. Now, when you start the game, Casper will start with Ghost Power, Fire Enhance, and Ice Enhance spheres.
