Guitar Hero World Tour DVD9 to 2xDVD5

[bad69]

it works, just follow the instruction posted by senseman.
easy, copy all contents to DISK1 folder, make another folder called DISK2 and move from DISK1 to DISK2 these files Data12, Data13, icon, autorun. then edit autorun like senseman shows in his post and the burn or create iso with labels DISK1 and DISK2. there a hidden file also on the original game disk called .AspyrBuild.Guitar Hero 4.EUR_EFIGS_SR.90751. i've copied that one on both folders, just in case.
when it finishes installing it will say wrong disk, but you have to switch to DISK1 and then you can play the game.
