Reset While in 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.


Find a Rare Card:
If you walk around and talk to people in the game you will find that a few people will talk about a strange guy named Imankinu? If you beat him 3 times he will give you a rare card. (I won't tell you what it is so I don't spoil the surprise).

Unlimited Energy Cards:
After you defeat the first person, go and defeat him again and to get a booster pack full of energy cards. You can repeat this trick as needed.

Retry Battle:
When you have a bad outcome or use a wrong attack in a battle, just turn the system off. This will save the battle, which you can return to and repeat your turn. This is useful when you do not want to lose a Pokemon. Simply allow your opponent to attack, then turn off the Game Boy.

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

Get different cards from Professor Mason:
Save the game before reading the e-mail from Professor Mason. Whenever you get a type of card you do not want, reload the game. The cards will be different when the game is resumed.

Booster packs from Professor Mason:
Professor Mason will give you a booster pack after every e-mail he sends you.

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

Energy Booster Pack:
After getting your own deck, go to Sam and offer to play a real duel. You will use the same practice deck and the flow of the game will be the same as during the tutorial. If you win, you will get booster pack full of energy.

Familiar Face:
When you go to the Psychic Card Club there is a person in green. He is your character in the Red, Blue, and Yellow versions of Pokemon.

Walk Faster:
While walking, hold B to move faster.

Faster Card Shuffling:
Press B if you do not want to wait for the cards to be done shuffling.

What to Use and What Not To Use:
When your fighting the legendery card masters, don't use a fighting deck. Start with a water deck then colorless then plant/electric and then the same colorless you use in the 2nd battle.

Ishihara's Disappearance:
After you trade Ishihara all the cards she will disappear. Go to the Rock Club and a woman will tell you that Ishihara has left.

Imanuki Card:
Go to each club lounge until you find Imakuni. Then, battle him to get four booster packs for each victory. However, he may instead give you his Imakuni card. Repeat this until you have most of the cards needed to build a healthy deck.

How to Fight Imakuni Everytime:
First find Imakuni and battle him and beat him. Then when he leaves save in your diary and turn it off. Then if you look in the gyms you will find him in the corner of the books.

Different cards in Challenge Cup:
When you are in the Challenge Cup, save the game after defeating the second to the last opponent. After you defeat the opponent and win a card, if it is one that you already have or do not want, shut off the game and continue from the save. You should be at the very last opponent. After you defeat him there will be a different card than the last time.
*Note: This may be repeated as many times as needed.

Fire Club Trade:
To get the Lv.9 promo Slowpoke easier, put all of your energies except one in temporary decks. Then, talk to the boy. He will reveal the location for only one energy.

Finding Mitch's Students:
In order to fight Mitch of the Fighting Club, you must first defeat his three students. They are all training at different clubs. Jessica is in the Lightning Club, in the room on the left. Chris is in the Rock Club in the same room. The last student, Michael, is in the Grass Club just as you walk in. He will be next to the plant. After you defeat them, they will all return to the Fighting Club.

Grand Masters Victory:
When you defeat the Grand Masters, go to the deck machine on the top of the screen before you get the cards to build a strong deck. If you do not do this, the game will proceed to the credits and you will have to battle again.

More cards from the Grand Masters:
After defeating the four Grand Masters, go back and fight them again to win more cards.

Defeating Ronald:
After you defeat the four Grand Masters, you will battle Ronald. He got to the cards one step ahead of you. Ronald's deck already has the four legendary cards, and thus is difficult to beat. Use Hitmonlee's (Lv. 30) Stretch Kick and knock out Ronald's benched Pokemon one by one. This is best done when he has his Kangaskhan on the arena, because he will need three energy cards to retreat. Since this kick does not apply resistance on the benched Pokemon, they can still be hurt even if they have resistance to Hitmonlee (Fighting).

Ronald's Revenge:
After you get all 228 cards, go to the Challenge Hall and the last person you battle will be Ronald.

Challenge Cup Prizes:
Go to the top center of the game map to find the Challenge Cup. You can compete in the Challenge Cup located in the Challenge Hall after you obtain your 3rd and 5th medal. If you battle there, you will get a rare card. It is hard to get in, because it is usually closed. Keep on visiting after every battle. If you enter, you will fight three trainers. The third one will be Ronald if you did not complete the game. After you complete the game, Ronald will not appear. These are the cards that you can get:
