guys you will NEVER see a firmware hack for wii dvd drive, simple reason is that there is no firmware onto it, the wii itself sends the firmware on bootup, that firmware is signed, u edit it, it wont work, u need a kernal hack for it. its worth a try if ur interested, does the same as most of the modchips, unlocks the drive, sends it codes wen it needs to and it allows backups to play, but it doesnt "flash" it in any way as the other guy was stating, id just stick with modchips atm, alot better
