tyler, i think your missing the point of aussie's question...would the dumb ol' gamecube be able to discern the difference of a alien barcode fitted into any old generic gamecube disc (whether it be original media or backup). It's obvious there are machinist tools out there, that once, when the barcode section of a disc is bored out (probably a game like luigi's mansion), you simply compensate for the 'bite' of the bit. When all is said and done, you have a snug fit, and then simply use a polyer cement of sorts. Of course this all means nothing if a barcode is married to its game.
