Actually you need a special drive to read Wii Disc so is not software related but hardware limitations that show low support. There is a pretty good and cheap drive you can get at eBay to do that and you can just use any Wii application that could dump Wii games to your PC. In my opinion you should use one of the USB loaders to dump your game to an USB drive that way you don't have to worry about antyhing else just copy it over to your PC.
