I recently acquired One Piece: Grand Battle!. It is a very nice Playstation 2 game IMHO.
Tyreece and I spent a lot of time on the game, and cuz we enjoy cheat codes we found this one and I thought I'll share it with you guys:
Play as Mr. 0 Crocodile Unlock characters one through fifteen. Then, select Ms. Sunday in Story mode on any difficulty setting. During the ending credits, hold L1 and press Down, X, Left, Down, Triangle, X, Circle, Square, Up, Circle, R1, Left, Triangle, Right, Square, R1 to unlock Mr. 0 Crocodile. If you entered the code correctly, you will hear a sound. Alternately, after unlocking Hawk-Eye Mihawk in the “Mr. 2 Bon Clay” code, successfully complete Story mode with Ms. Sunday/Nico Robin, then hold L1 and press Down, X, Left, Down, Triangle, X, Circle, Square, Up, Circle, R1, Left, Triangle, Right, Square, R1 during the ending credits. If you entered the code correctly, you will hear a sound.
Enjoy!
