i just ripped spore hero using rawdump2.1.the rip was successful and the iso was 4.37. i burned it at 4x and 8x using image burn as well as nero. both discs lock up my wii as soon as the wii drive tries to read them. i have to eject the disc and reboot the wii. the wii has fw 4.2 and is modded with a wiikey 2. the retail game works fine. i have never had a problem booting backups in the past no matter what speed they are burned at.
