Unique problem! I wonder what is wrong...
I have a new Wii LU64xx (US) with Wiikey2 v1.3.
After I tried to run my Rock Band 2 backup, without instruments turned on, I can't play ANY Wii games through the Disc Channel. And, what is strange to me, I still can play Gamecube Games this way!!!
When I tried to run the game, the system got froze. After that, when I insert a Wii game (backup or not), the disc spins, and after some time it stops. Then appears the message "please insert disc", and automatically stars to spin again... Stays in this cicle, over and over...
I've changed all the Wiikey 2 options.
I've downgraded my system from 4.1U to 4.0U, without any changes.
So I've installed "Configurable USB Loader" on HBC, which is capable to launch game discs. And, my surprise: all my games goes great through it!
So anybody knows what happen to the console? Or, what is better, anybody knows how to put my disc channel working again?
