I Used MultiGameISOCreator to put 3 games in one disk, and selected the USA version on the top right corner. When i inserted and ran the back-up game using GC Backup Launcher (by WiiGator). It opens the application like it usually does and then once the Wii reads the disk the screen turns black/white and starts flickering. All the games I have in the DVD are NTSC-U.
Wondering if there is any kind of help out there.
PS: I tried running a GC game ISO alone in a disk and it worked perfectly.
