The game - Battle Spirit Digimon Frontier - WonderSwan Color | WSC

The sequel to Digimon Battle Spirit combines all the intense combat from the original game with brand new features. In Digimon Battle Spirit 2, you must restore peace to the digital world by defeating Kerpymon. Like the previous game, you can collect spirit orbs that allow you to "digivolve" into your bestial form. This time you can use ancient spirits to dig into the ancients. You can also unlock an exclusive mini-game in single player mode, or pair up with a friend for two custom face-to-face battles.
