Digimon World 4 Cheats

Unlimited Bits and Items
This trick requires your main Digimon as player one and any Digimon as player two. Give all your Bits to player two. Then, save player two at the Save Keeper. Next, have player two give all Bits to player one. After that, have player two quit the game at the Save Keeper, but this time without saving. Then, go to Call Keeper and have player two join in again with the same Digimon. Repeat this from the beginning until you have 9,999,999 bits, both in the bank and pocket. You can also use this trick to duplicate items. This is very useful if you want to give some rare weapons and armor to a friend.

Double Axe description
The game states that Double Axe (all types) is a bash skill weapon. However, when you use it you will gain the blunt skill.

Easy experience
In single player mode, repeat the tutorial about fifteen times, then go to Death Valley. Once there, follow a path and fight some Goburimon; do not go across the bridge. Follow the path up and fight the Goburimon. They will give 10 experience points each. Break, then get the Gate Chip, use it, and repeat. Additionally, go to Death Valley, then to the Fortress. When you are inside the guard room, defeat everyone for 32 experience points per kill. After all the doors open, go outside and enter the fortress again. This must be done two or three times to reach the next level.
