A few pointless but fun cheats
If you play 2 Player mode and the second player wants to play as the same Digimon Player 1 picked, they can do so by holding down the SELECT button while selecting that same Digimon. While Calumon would usually say "Oh no..." or something like that, holding down the select button will allow Player 2 to play as an alternate coloured Digimon. This also works in vs. Computer mode for the COM player.
Also, if you want to give the 01 Digimon's partners (Agumon, Gabumon, Patamon and Gatomon) their series 1 looks instead of series 2 looks, hold down the shoulder buttons (L1, L2, R1, R2) while selecting the Digimon. This also works to give Ken his Digimon Emperor outfit when you play as Wormmon. Don't try this out on any other selectable Digimon though, it only works while selecting Agumon, Gabumon, Patamon, Gatomon or Wormmon.
