Announcement! 3 D Games

If it's written in C/OpenGL, then it might be portable to the Dreamcast.

If it uses C++ or Direct3D, chances decrease. The C++ library on the Dreamcast is not complete, and getting a more complete version (STLport) working is pretty tricky. We have no Direct3D, so we'd have to rewrite the rendering system from scratch.

If it's written in any other programming language, or if the game is full of Windows-isms (like using the Win32 API for everything, instead of using more portable standard C libraries), then chances drop to "slim" or "none".
