Convert Game Cube .gcm to .iso for use with Wii WBFS USB drive.

Hi.I have used Wii/GameCube DVD/CD dump to ISO tools to create an ISO from a GameCube disk. I could then import the GameCube disk using Wii Backup Manager to add the image on to my WBFS USB drive.Recently my child wanted the old Super Mario Sunshine game. I've downloaded the .gcm file for it.I read one suggestion to rename the .gcm file to .iso. This did not work for me.Is there a tool or special process to convert a .gcm file to a .iso or .wbfs file?Help...Thanks in advance.Tim

When did you buy your wii?, if it's of 2008 or later you cannot run GC games, not even vía USB i think, due that the System lacks some files to read the format
