That happent after I just got a Wii U console and tried to connect Wii Remote to the console, the Wii Remote won't connect and Wii and Gamecube games don't show on the Wii menu anymore.
Ok so people have been wanting to know how to do infinite coin glitch so here.this only works on New Super Mario Brothers Wii.
Go to World 4
Go to The PURPLE CASTLE AT THE END OF THE WORLD
Equip an ice power before you begin the Purple Castle at world 4. Once you have done that go into the level.
Go To the part that has a turning metal fence. It is pretty big. It has 4 Koopas on it or something.
Get on the Turning part but DONT TURN IT YET.
When a Koopa is on the Turning part on your side, Jump and freeze the koopa, then land back on the Turning part and PRESS THE BUTTON TO TURN THE TURNING PART. If you did it right you will have a koopa frozen on the ground and it will be spitting coins infinitely until you die or go off screen.
