Wow kool, is it faster?

It is about as fast as emulamers build using picards GAPI tweak.
Infact emulamers build is as fast as it gets, since it just transfers the framebuffer to the 2700g. The OpenGL build needs to convert the frambuffer into a texture(which has a really strange format) and renders the texture to a quad using bilinear filtering. The conversion to a texture format is done in software and takes about 5.6ms using a custom assembly routine, while the second step is done in hardware and is almost neglible.
I first used the standard OpenGL implementation of texture conversion and almost gave up, since it took 34ms!!! Then i wrote the conversion in assembly and it was much faster :)
