Gameplay Differences

Fightable Bosses & Tournaments

The Tournament names are different between versions. Some Navis and Tournament scenarios you get are also dependent on the version. These version-exclusive bosses are the only way to obtain their chips. It is impossible to get FireMan and NumberMan in the first continue, except in the opposite version via Waiting Room.

Due to the Waiting Room feature, these opposite version Navis aren't as locked away like other games. You will be able to trade Navis over from the opposite version, complete their scenarios, and battle them. This is also the only way to max out the Records of opposite version SP Navi Chips.
