I was wondering about how one would create a disc that will work on an unmodified Wii console. Clearly Datel have managed this with their Freeloader; the question is: how? What is the difference between a burned Freeloader, and a genuine one from Datel? Well, the most obvious thing about the Freeloader disc are those little circles that are at the centre of the underside of the disc... Do these trick the Wii into thinking the disc is a real Wii disc. If so, then could we add our own little circular notches to discs to make discs that will work on an unmodified console? Or is there actually a small amount of data written to the disc in a region that is just not there on a DVD-R? What does gbatemp think? Is this at all possible?
