great work bonapart!!
Ive tried a few of games out, all work without open gles fine.

Ridge racer type 4 starts but has none of open gles acceleration or
texture blending/mip mapping.

gdarius works with gles, looks to have black edges around alphas texture issues on the, some sort of premultiplication problem.

crash bandicoot 3 works with gles but still has the Zbuffer xray issues

megaman legends works with gles. same black edges around alpha textures such as clouds.

crashbash works pretty well with gles but not as fps wise with gles off.

hope this info is useful in someway.
cheers
