Hello! I'm using the lastest firmware. Yesterday I wanted to play Big Brain Academy with some friends in Versus Mode. They both have a M3 Real. Each time we all three joined a game and started it the connection was lost and the DS was shut down. The strange thing is that they could play without problems when I didn't join the game. So it's definitely no rom issue. Singleplayer works great! Can anyone confirm this problem or help me solve it please?
