I've just received my pre-soldered Wiikey in the mail from Modchip Central. So I opened up my Wii, clipped it on, and put it back together. I then downloaded the Wiikey 1.9s update from their website, filechopped it, made it a GCOS disc, and burned it to my Memorex DVD-R disc. When I put it in my Wii, it said the disc couldn't be read. I tried doing this 4 more times, some with making it a GCOS disc, some without. I then tried to burn Mario Kart: Double Dash onto a disc to see if that would work. No luck. Am I doing something wrong here? Any help would be highly appreciated. Also, if it matters to anyone, my Wii serial number is LU304042256.
