i have copy of Boom Blox on dvd burned that works fine however i want to make a back up copy to use in dolphin and with usb loader. if i make copy of dvd with imgburn it comes out as 3.99GB but is not recognised by wbfs or dolphin or any other app as being wii game, also doesnt work when burned back to dvd. since usb loader does not read backups in wii drive and the wifi/lan disc dumper does not work for me how can i make a working iso of this dvd??
