[noob question] from directx to opengl

[Tesqua]

Assuming you have the code of a game, is it possible to convert it from using directx to opengl?

The reason of this question is that i keep following saintsaga project (http://www.saintsaga.com/) for years, and I think that this fanmade game would be perfect for a "handcrafted" console.



PS: sorry if it's the wrong section

It's not that hard to do, if you've written proper wrappers for everything. However converting from DirectX would require a bit more than just OpenGL, you need stuff for input and audio as well. Today that's SDL, but SDL has many drawbacks unfortunately... I'd much rather see one could use OpenGL ES and OpenAL in addition to an input library. Oh well...

it all depends on how organized the code is. rendering is usually a quite small portion of the overall code, and if sectioned off properly most games (even pretty commercial ones) could probably be ported in a couple weeks.
