[TrashyMG]

Found this as interesting.. released under the MIT license.

Wrap that with the GL->GLES layer and porting things to the Pandora may get ever so slightly easier.

Are there many Open Source DirectX games?

I have a few interesting titles in my todo yes. So defenetly a good new!

Ah, you don't ported EVERYTHING ? Thought so ;-p.

Not yet, but I'm working on it

Even though programs with shaders will run, I don't translate the shaders or properly set up render calls yet. It's practically a stub.
As another side node: Dota 2 is noticeably slower when using the OpenGL layer than DirectX (on lower-end hardware).

I think i saw many in Sourceforge

Adequate licence. Are the many DirectX based games that are not also tied closely to other Windows APIs?


Is this conversion layer better than Wine's?

Well, every game using it so far requires some OpenGL 3 features... maybe that's just the answer to the "finally port it to OpenGL 2.1, damnit!" choir

Apparently there's one or two effects in DOTA2 that are somewhat problematic, as far as I know disabling a certain setting vastly boosts performance with the free drivers. Valve did an early blogpost that definitely showed a huge performance improvement when using this layer instead of native D3D with L4D2.
