GP2X Hh Colours Are Wrong

[Orkie]

I've been playing around with sdk2x on devkitARM over the past few days and while I've managed to get a 16bit framebuffer going, the colours are all too pale. For example, pure red comes out as pink :S. Any idea how I can fix this? I've uploaded my test code (copy fb.bin and run.gpe to an SD card and launch it to see what happens, source is also in there): http://x11.gp2x.de/devkitpro/test.zip

No gamma table?

How do you set one up? I have been using the function rlyeh gave me (commented out in the posted code) but it didn't seem to do anything at all.

Shouldnt you call that function *before* any drawing call in order to see the changes with a little time enough?
Btw, I'd bet my pants it's about gamma or LCD timing related.
