Okay I have Dvd+R (I know -R is reccomended but i couldn't get any.) I burrned Guilty gear Accent core to it. I didn't cahnge the book type because for some reason the dvd drives manufacturer wasn't listed, I chose a random one and it said "error in finding blah blah blah!". So I burned it and I plopped it in my wii. My wii just keeps on turning the disc and stopping (or so I hear from the drive), The blue light occasionally comes on, and the screen stays black while im loading gamma (note: Its currently been ten minutes and its still "loading" the disc). When i press home a quick glimpse of a green screen comes up and then it flashes to the System menu. When I go back to gamma, it say "System files are corrupt, please see Wii manual to continue". So I restart it and try it again (cause my System menu is fine) and the process recycles.
