Ok, this is a new one. Went to play EA Playground with the kids (a new rental, never played it before), and discovered that my P2 controller is...reversed. As in, mirror image. Left is right, up is down. Oddly, when I bring up the Home Menu, even the hand icon is upside down?! Messed up.
I resync the controllers, this time using the backward one as P1 instead of P2, to see if it is a problem with the game. Nope - now P1 is backwards. The problem is with the controller. But, still, if you go out of the game and back to the main menu, the controller is fine.
I fire up Mario Galaxy and play for awhile. Controller works fine. I attribute it to some weird quirk of the game (I even went down to Blockbuster and got another copy of the game to rule out a bad CD of some sort, even though the programmer in me can't imagine how that would be it).
But then, while playing Wii Bowling with that controller, we get the same problem - everything is backwards. Ok, now this is a problem, I can't exactly play meaningfully with one broken controller.
I call Nintendo, who admit that they've never heard of the problem. They are intrigued, though, that even the hand icon goes upside down. The guy gives me the "unofficial" Wiimote fix - turn it upside down and whack it a few times.
And you know what? It worked! My little hand icon turned rightside up before my eyes, and now it's working fine.
I know everybody's familiar with the "whack it" fix - I'm just blogging this because no amount of Googling told me anything about the "mirror image" problem, so I figure the next person that comes along looking for it will know, the whack it solution works for that, too.
