So the girlfriend got a third party balance board and Wii Fit Plus from her parents. And now it's up to me to make that shit work The brand is "SnakeByte" or something..
It doesn't want to sync properly. The first time it just worked, but when the girlfriend wanted to use it again later it didn't work anymore. The game asks me to press the sync buttons on the BB and Wii > I do so, nothing happens.

Anyone with experience with (third party) balance boards?
