Free movement mode

Move Casper to the topleft corner of any game location. Then, hold Up/Left + L1 + R1 + Start (this will freeze the game). Release Up/Left + L1, and press Down/Right + Triangle while continuing to hold R1 + Start. If you entered the code correctly, the game will resume in free movement mode. Press R1, then use the D-pad to fly over any wall. Press L1 to resume normal game play.

Faster movement

While playing the game, hold Triangle and press X, R1(3). Note: The inventory screen will appear during entry of the code. Press Triangle to resume game play.

All morphs

Instead of using the puzzle pieces to get the morphs to finish the game, use the following trick. Enable the "Free movement" code. Starting from the main hall (with the twisting floor), move up the left staircase. When the next section is done loading, press R1 to go over that wall, then go down until a room appears. It contains all the morphs, items, and food needed to complete the game.
