One Piece: Pirates Carnival Cheats

Play the board game, and in the end, all the games that you've played will be unlocked in the versus mode. This will also unlock new bigger boards, and all the cards that appear in the board game will also be unlocked in the gallery.

Simply play each of the games in Member's Game and the Captain's Game once and each of them will unlock the voice collection (you don't have to win the game, each game will only unlock one voice collection)
