thanks alot now i feel safe going online

but there one thing i wanna know
whats de-sync mean?
When playing on Wifi, the server synchronizes your game with your opponent's, this causes the game to read the input from your opponent and send it to your Wii for your game to read, and at the same time, the game is taking your inputs and sending it to your opponent, allowing the Wifi games to be played (at least thats my theory).
De-synch is when this is disrupted, and the two consoles begin not sending the data at the same rate, causing problems on Wifi, and making conducting matches very difficult to do.
