It doesn't use any. ixemul is *not* needed (it compiles just fine
with libnix).
The player needs GetTimeOfDay() but that's often supported in the C
library or easily emulated via the timer.device.

WritePixelArray() is pretty fast (when patched :). Or use one of the
hundreds of C2P algoritms floating around and blit it into the
window. Not exactly hard stuff.

There isn't any. Except in the newer versions (and only in the
16/24/32bit mode - it assumes the data is stored GBR instead of
RGB). In fact the newer versions of the flash library don't support
anything less than 16bit!

Oooh. That must be hard.

As I said. It doesn't need ixemul. The X11 player uses precisely 1
function that is not implementated in GCC's standard C library
(ignoring the X11 stuff, which needs stripping out anyway).

I have been for the past 2 years. I have a feeling that the plugin
stuff is incomplete in 2.2. 2.3 is supposed to have NetScape
compatable API (but I've not seen 2.3...).
