Well this is an odd one. If loaded this sucker into ISOBuster, UltraISO, WinRAR (ISO-compatible version), Nero, and Nero ImageDrive, and each and every one has reported it to be corrupted and unrecoverable. It's the correct filesize, BTW. Now the funny thing here is that Dolphin, after renaming it to a .gcm had absolutely no problem playing it. No resource issues, no extra plugins, and no ini hacks. Simply Dolphin on the default settings, straight out of it's zip file. Any help would be greatly appreciated. NOTE: I have not tried CloneCD as of this point. If I have time I'll give it a go later.
That's because GameCube game images can't be read by PCs. So, basically, that's normal. Same goes for Xbox games. And that username of yours looks familiar... like one off of LUE...
LUE? Can't recall that one by abbreviation only - is that another tech board? And yes, I'd figured that already, but wasn't sure enough to check.
