In-game reset:
Press A + B + Start + Select during game play to reset the game.

Get heads on coin:
Press A when the Pikachu coin is spinning right on Pikachu's face. Note: This requires precise timing.

Get tails on coin:
Press Up just before the opponent's coin is displayed when battling an opponent. If done correctly, it will land on tails most of the time.

Free booster pack:
To get a free booster pack, go to your PC.

Unlimited energy cards:
In Dr. Masons Lab, both Sam and Aaron will give you a pack full of energy when you defeat them/ Sam only plays with two prizes, making him faster to defeat.

Organize your cards:
Press Select to organize your cards.

Charizard card:
Select the Charmander and Friends deck at the start of the game.

Hint: Easy medals:
When you have a lot of cards and not a lot of medals, make a deck of Pokemon cards that is strong against the medal you want. For example, if you want the Fire Medal make a deck of Water Pokemon. Note: This trick does not work well for the Psychic Medal, because Psychic is weak against Psychic.
