There is a time that you must go into the basement on the school. To use the ladders, press Square on the arrows.

Use UMD Recognition and insert Tag Force 1 UMD to unlock Egyptian God Cards.

There are free cards all over the map. Look on the ground and behind some walls to see if there are any hidden cards. Some cards are being stood on. To get these cards, skip school and go to where the people stood on the cards.

When dueling against Axel, have a monster out on the field that is the only one out that negates effects targeted to its own type (for example, Cyber Phoenix). If the CPU has Tri-Blaze Accelerator or Blaze Accelerator out and selects the monster (Cyber Phoenix), its effect will negate Tri-Blaze/Blaze and Axel will not discard a Pyro-type monster. This will continue in an infinite loop until you exit the game or turn off the PSP.

Enter this code when you buy booster packs: Up, Up, Down, Down, Left, Right, Left, Right, X, O.

Successfully complete the game with Aster Phoenix as your partner.

Use the following UMD with the "UMD Recognition" feature to unlock the corresponding card.
