Unforunately not. Gamecube dics cannot be read in any commercially available drive other then the actual Gamecube itself. But there is a way to make your own ISOs which involves linking your GC to your computer with a networking cable and ripping the game to an image on your hard-drive. If you're interested in that path then I'd recommend doing some searching in Google on how to make Gamecube ISOs or how to rip Gamecube games.
