Well, what are the multiplayer options here in the US?... (and if anyone has the JPN version, we can contrast)
Edit: I ask since no reviews seem to cover the aspect, yet the back of the game indicates single cart and multicart multiplayer options.
Edit 2:
Looks like multiplayer is simply a deathmatch between players. No Co-Op modes. Multicart looks to just let you use the items and weapons you've collected.
