View the opening sequence twice to see Blackwargreymon instead of Wargreymon in the animation at the beginning of the game. Note: This does not unlock him during the game.

Once you get the generator parts in the first room in the dome, talk the man on the top right. He will sell all the items that you can buy when you join a club.

Do not run away from battles and you will earn experience points. Also, fight stronger Digimons for more experience points. After you defeat Leomon in the first dungeon, you can return and fight a level 5 Gazimon and a level 5 Gizamon. After defeating these, you gain 39 experience points and 260 bits. Note: Only use this trick when you have at least one or two champion Digimon, as they are quite difficult to defeat.

Digivolution Points determine what Digimon you will get when you digivolve in the future. The only way to get DP is through DP Up item or the old fashion DNA Digivolution. DNA Digivolving is better and makes your Digimon stronger.

All Digimon digivolve at 11, 21, 31.

2 Champions = Rookie
2 Ultimates = Champion
2 Megas = Ultimate
Champion + Ultimate = Rookie
Champion + Mega = Rookie
Ultmate + Mega = Champion

The DNA digivolved Digimon's form is always one below the lowest Digimon form in the pair of the two Digimon.

There is a formula to figuring out the maximum level of your Digimon when you DNA Digivolve:

X = Larger level of two Digimon
Y = Lower level of two Digimon
Maximum level = X + Y/5
