Hi I have a wii which has been modded before. Might even have a chip in it. how do I tell? Basically I have followed Zero's tut and updated the wii to 4.2 and installed darkcorp 1.1 and neogamma Beta9 44. But it wont play Mario Galaxy 2 from disc keeps coming up with dvd error. On my other wii it will play just fine the same disc with darkcorp installed. So what am I missing?
