Digimon World DS/Controls

Controls in Digimon World DS are divided into 3 main groups: World, Battle and Menu

World

Battle
"Battle" refers to a situation where your digimon fight other digimon. When you walk in a dungeon, digimon will randomly appear and fight you. (Much like in RPG and Pokémon games)
