You didnt answer this on your faq so im going to ask it...

Why OpenGL when the Xbox was a microsoft machine using Microsoft DirectX? surely conversion of graphics functions would be simpler (and more obvious on what to use) if you just used DirectX? It would certainly keep it truer to the original system

First, let's go back to the whole HLE vs LLE thing. If I was using HLE, I'd undoubtedly go with DirectX/3D because that would be even more strait forward. But since I'm not using HLE, I can use whatever the heck I want :) I want the actual graphics hardware to be emulated rather than the XDKs DirectX APIs mainly because I don't have every XDK and it would be impossible to get them all plus I don't want to be limited to XDK versions and such. I'd much rather emulate the hardware.

Now on to the OpenGL thing... sure OpenGL has it's drawbacks in all, but are a number of reasons why I choose OpenGL over Direct3D. First of all, I want to see this emulator get ported to Linux and Mac OS more easily. I don't want this emulator to be limited to only one OS either. Second, the NV2A's registers can be easily emulated through OpenGL because at the hardware level, it's very OpenGL-like structure. Third, I just want to prove that it could be done :)

There are some downsides to using OpenGL though, but they are far and few, so I figured, why not be the first to do it?

fair enough as long as you have good reason

Wise thought.

Oh yeah, I forgot to mention, I'm working on an internal HLE Bios too because since I'm not ready for actual Bios emulation yet. Working on a method of wrapping PsCreateSystemThreadEx, it should be rather easy though.
