I would like to know this too. The info I find seems contradictory.I guess i'm too much a noob. In the intro to this section of the forum it states that hardware modchips have never been compromised, then I read inside the subforum about 4.2 bricking wiikeys.
WIth just the wiikey 1, 1.9config, and 3.3U, are we safe to do disk updates?
Just bought the motionplus controllers and I think I have to update for sports resort....
thanks for any help
