its a new fix, look here at WiiGators post http://gbatemp.net/index.php?showtopic=107074&st=4065 as for the hook type its a setting in the config menu of the backup launcher. i'm guessing disabled would be the VI (default)
I have Guitar Hero 3 (ntsc) and two gh3 customs (both ntsc) Is there any way to change the game ID(all are RGHE), one to pal and one to ntsc-j so each will have its own save file?
