Pocket Digimon World

In this game, your task is to gather all lost items from the Digimon Museum. All these items can be found from
the PocketStation game, in which the majority of the game takes place in.

In the PocketStation side, you can train up your Digimon, battle through enemies in the map,
and also either battle against your friends Digimon or Jogress evolve them to make the Digimon
more powerful, using the PocketStation's built-in IR communications.

In the PlayStation side, you can review the collected goods in the museum, such as pre-rendered
video clips, Digimon evolution lines, photos and such. You and your friend can also bring your
Digimon in PocketStation to a battle in 3D! Also, these Digimons can also be imported to the Japanese
version of Digimon World 2!

Digimons you can get from this game are: Agumon, Biyomon and Veemon.
