Gameplay
The gameplay is almost the same as the Playstation games, except unlike the Playstation games, the gameplay in this game is more simple. This is because this game featured less special and combo moves due to the Wonderswan controls.

The items found during the game are from both Grand Battle! and Grand Battle! 2 games.

The game modes are the same as in Grand Battle! (Event Battle, Grand Battle, Options) plus a Bonus Mode, in where you can see your card collection or play the mini-game (see below).

Unlockables
The game featured a unlockable card collecting system. To collect those cards, the player must accomplish certain task, such as beating the game without continues, etc.

In the 4th stage of Event Battle, the player must play through a bonus game which consists of beating as many Kung Fu Dewgongs as you can within 60 seconds. You can later unlock it as mini-game.

There are 2 unlockable stage. Also, Luffy, Zoro, Usopp and Sanji have unlockable special moves.
