Hi, I have some GameCube games on my computer, some of which are ISO files and others are GCM files. I have a Wiikey2 installed perfectly on my wii, and I burned off the games. They were all burned the same way. The ones I burned that were ISO files play perfectly fine, but the ones that were GCM don't work at all. In fact, most of the time it gives me an error when the Wii tries to read it. Is there a reason this is happening?
