Hi,
i have a problem with retroarch+xmb on ArchLinux32bit: when i run it i have
black screen, monitor led blinking and i must reset pc.
This is final output error of retroarch:

[INFO] [GL]: VSync => on
[INFO] [GLX]: glXSwapIntervalEXT(1)
r300 VP: Compiler error:
Vertex program has too many instructions
Using a dummy shader instead.
r300 FP: Compiler Error:
compiler/r300_fragprog_emit.c::translate_rgb_opcode(): translate_rgb_opcode:
Unknown opcode DDX
Using a dummy shader instead.


If i run it with "LIBGL_ALWAYS_SOFTWARE=1 retroarch" it works but is very slow
(games run at 30fps).
I use xf86-video-ati driver and mesa.

Retroarch devolopers advised me to ask here.
