This is really starting to annoy me as it has happened in the last 4 wifi battles I have played. It seems that whenever someone is starting to go downhill in a battle, they will shut off their game to preserve their precious battle record. This is not neccesary!! If you want to keep a loss off your record, simply wait until you leave the wifi area then shut off your game. The game only saves before you enter wifi mode, NOT after. Therefore, your loss will be erased, while your opponent can keep his win.
