Xbox port not possible now?

Well, it would really depend on what the Xbox graphics bottleneck on. Some 2D games are actually horrible stories for modern OpenGL emulation, for example, because they use tricks or lots of draw calls to render. For example, doubled blending modes, copies between VRAM and RAM, and alpha test / stencil testing trickery.

Also, you might be surprised - many games will use 3D rendering even for 2D graphics. There are games where lighting or etc. is used - in 2D - just to make a button show visibly highlighted. It might be hard to remove any 3D-specific rendering code and retain any hope of compatibility.

That being said, definitely get rid of anything under GPU/Software/. That's the software renderer, so it can just be stubbed out.

Okay - note that if you want background music to work, a *recent* version of ffmpeg will be needed. ATRAC3+ (used by a very large percentage of PSP games) is only supported in recent released versions, and with a patch by that. This is thanks to wonderful work by Maxim Poliakovski.

Well, we used more C++ after switching to 2013:

So thereabouts would I suppose be a good place, maybe. That being said, there's been a lot of improvements since then. That was back around v0.9.9.1.
