I just got rockband 2, the iso is PAL my wii is ntsc, normally i just use WiiFrii to patch the iso. but i get a " ERROR: Couldn`t read "ISO DIRECTORY" " . the iso is not corrupt because other programs can read it such as Wiu, i have tried using Wiu to convert it to NTSC but the game freezes when i try to start it or goes blank, i think this is because Wiu doesn't patch the video region? any help? i have preloader installed and have enabled region free wii disks but once again it doesent launch but if i disable region free wii disks it doesn't even recognize the disk at all.. any help?
