yeah, and you call battle with others or urself by using it..

well here is how to create multiple screen digimon:
option > select quad > hilight which screen that is empty using touch screen (example screen 2) > option > select reset device and an bandai logo an egg appear.. do the same on screen 3 and 4...

need to have more then one digimon in multiple screen option..

select network setup > network type loopback > start listen > select bot digimon to battle and it would start
