I have a black Wii with 4 ports for gamecube controllers, 2 gamecube memory cards, and 2 USB slots. I got USB loader GX with games working, and now when GF puts in Just Dance 2 the system says it needs an update. Will this update bork the Wii? If so, what's the solution?

Also can't get the Gamecube games on the USB drive to work. I have the USB drive formatted to 32Mb. Not sure what I did wrong but it's possible Dios Mios didn't get installed.
