How to read the GC barcode??
 

The barcode on the inside ring is what determines what the Gamecube can read. I colered over it with felt pen, then the GC would not read it. Kinda cool. I think duplicating that is going to be a bitch!!

Yes that will be a problem, but it was the same with dreamcast. It also had a "barcode", but with a boot disc you can swap this. I am sure the datel freeloader will do this, because he swaps this boot sequence - if not somethng similar will do, and from bootloader to bootdisc i suppose are only a few days.
