When you win the 8 medals and you want to win the legendary cards; if you lose, you have tobeat all of the other trainers all over again; well now you don't have to. When Rod says to prepare your deck, put yes and save in the diary. Then in case you lose, you turn off the game and in the main menu put "Continue from diary" and you can try to beat them for as long as you want.
The Right Decision
If you accidentally made the wrong decision in selecting an attack,don't worry, just simply press A + B + select + start simultaneously and you will be back in the main menu. Choose "Continue Duel" and you will see that it's your turn again.
Imakuni can be found at either the Science Club, Water Club, Lighting Club and Fighting Club. After you beat him, he will give you 1 of each pack of cards. Each time you beat him, you must save and reload your game to make him appear at either one of the Clubs again. He will not be at the same club as the previous time you met him.
Look through your deck without it reshuffling
To do this, you must have a Trainer card in your hand that enables you to look through your deck, to pick a certain kind of card, and then reshuffle the deck. Use this card, and then, instead of selecting a card, press A+B+SEL+START all at the same time, once you are done looking at the deck. This will Soft Reset the system. Choose Continue Duel from the menu, and you will get back into the duel with the same cards you had before you used this code. If you used Computer Search or another card that takes cards from your hand to look through the deck, those cards will be back in your hand.
