I have a 3.3U system. I have the HBC running. I have a disc channel with the Gamma Loader, and I have installed the necessary CIOS that comes with Gamma. I also have DVDX if that matters. Anyway, I can boot Smash Bros. Brawl (real disc) fine with Gamma Loader. But if I try several different burnt copies of Super Mario Galaxy, it doesn't load. It constantly tries to read the disc, but it is a black screen. Some white text occasionally shows up in the center but it disappears before I can make it out. It just stays black. I am not able to use the IOS downgrader because of a lack of network (no wifi). Are there perhaps any IOSs that I need to install to get this game to work? I have not patched the game at all. I haven't tried any other games yet. I have another burner I could try too, but I'm not expecting any better results.
