Make some sceFont functions fill in (fake) error codes
sceGeListSync seems to want a return value (fat princess, others)
Another missing sceKernelModule method (killzone)
Too many games crap out if the structs and the error codes are not set
to something sensible. Also, I've tried setting the glyph buffer to grey
to get something displaying, although it doesn't seem to work in
anything so far.
