well most of the existing software was written for SDL, so why would that know about a new 3d chip?
I have not seen any of the SDL/GL demos tho, that would make things a little more interesting.
I'm going to wait tho, first version of my gp32 was crap, first version gp2x was crap (oh man the horror stories)... I still have my gp2x-mk2-f100 and its nice. I passed on the F200's.. I want a pandy but will wait until the second batch or so...
