when i rename GCM to ISO... and burn it with nero.. the disc don't work on my modded Gamecube. when i put the disc in my computer it can't read the disc... it loads it as an CD image file... but it must be an DVD image file.. how can i rename GCM to ISO to create a real DVD image file....
when you boot nero, you choose your DVD burner, if you only have one you auto select it, Open the iso as an img, it will read your disk in the drive and burn it to the proper format. Makesure you finalize the disk.
