So I tried to emerge fceultra a while back, but couldn't because emerge told me that the version of gcc I was running had a bug that would break FCE Ultra. Now I've updated to gcc 3.2.3-r1 and the ebuild no longer complains, but when I try to emulate certain games (i.e. the first Super Mario Brothers), almost the entire screen turns gray.
The trouble is that because there's not much support in terms of docs, I can't tell if this is a compiler bug or if I need to configure fceu better. This happens with both the svga and the sdl versions...
