I have to download them from the internet? Wii DVD Dumper copied parts of the game dvd to an SD card – you have to than transfer them to a PC where they can be joined together to form a full Wii ISO 4. After that the RAW data has to be “unscrambled” before you get an ISO for burning to DVD. So a much easier and faster way to get a working backup of your Wii Games is by downloading a ready made Wii ISO from the net and using image burning software to copy it to DVD-R. All in just a couple of easy steps. Wii Accessories at unbeatabe low prices and with free shipping!
