yeah i am just wondering how to play wi-fi with my friend we have each others friend code when i form a party he clicks join and all you see is your friend code list
When he joins your team you should have a screen with all the people currently in your party, this could be called "The Lobby" if you like, when he's joined press the button to get on with gameplay. If you're not getting this Lobby screen with each of your characters in it, then maybe you're doing the whole process wrong or the Wireless connection is not stable enough.
You will have had to have exchanged Friend codes before hand. This is to stop people of a younger audience learning bad language from older players while everyone waits in a lobby with many other players and then there is the fact that the DS wouldn't be able to cope with it as the Hardware just isn't powerful enough to cope.
