Press Up(2), Down(2), Left, Right, Left, Right, X, Circle at the booster selection screen in the shop.
Go to the Lab, when it finally appears, and choose the password machine. Put in the following codes- note these cards will appear in the rental shop and you will be charged a fee that will come out of the duel points you win (I have more, but, I was unable to put them all on the form that Gamefaqs has provided):
Connect a PSP with Yu-Gi-Oh! Gx Tag Force 2 to your PlayStation2. Load the game on the PSP, then select the "Database" option, then then "USB Connect" option. On the PlayStation2, load the game, then select the "Database" option, then the "USB Connect" option. You will get 10,000 DP and three new cards. Note: This can only be done once per saved game file.
after you get a "blue-eyes white dragon",look in your album and the "blue-eyes" card is not a "blue-eyes" card it is "a feather of phinix" card.
