Instructions
Use the attack buttons to inflict damage on your opponent. The attack buttons are "X" and "Square" on the PlayStation 2, "A" and "X" on the Xbox and "A" and "B" on the GameCube.
Collect the Evo-Spheres that come out of other characters as you attack them. Once you have enough spheres, your Digimon can digivolve into a stronger form.
Press "R1" to digivolve on the PS2, "Right Trigger" to digivolve on the Xbox and the "R" button to digivolve on the GameCube when your Evo-Sphere gauge is full.
