After some searching I came across these blanks, which are to be suitable according to the other reviews for the Gamecube. I can only agree with me there; almost every blank is recognized by the Gamecube. However, one should keep as far as possible clean before and after recording the backup copy the blank, as even small scratches generate read errors. Small DVD cases as storage situation is better suited than the supplied screw. Nevertheless, I can only recommend this every Gamecube fan blanks, just because they are not a bit pricey. In this way I would like to praise one more time Amazon for his very, very fast delivery. Not even 24 hours of ordering, the blanks were with me, and with standard shipping. Simply TOP!
