Cheat: Character Changing Costumes
You can change the characters into another costumes by selecting a Digimon, hold L1 + L2 + R1 + R2 at the same time. Keep holding down and you get your different tamer costumes. I found that it works on: Taichi: Agumon,Wargreymon and Ominmons partner Matt: Gabumon,Metalgarurumon and Omnimons partner T.K.: Patamon and Seraphimons partner Kari: Gatomon and Magnadramons partner Ken: Wormmon and Stingmons partner(Suprisingly it doesnt work when it comes to Imperaldramon Paladin Mode)

Choose Same Digimon Twice
After choosing a Digimon on the character selection screen, highlight the same Digimon again and hold Select and X together.


Unlock Impmon
There is no password for Impmon, but you can get him by battling. First you have to be Terriarmon, next Guilomon, and then Renamon. They must be played in one-player mode and you have to beat Reapermon with each of them in that order. (To get to Reapermon beat each regular digimon.) Once youve done that you will have Impmon at the character menu.
