DXGL is currently a work-in-progress and is currently considered alpha-quality software..
See DXGL Features for detailed information.
See Version history from the downloads section for release information and previous version downloads.
Also see DXGL Test Results for some detailed tests performed occasionally.
What works:
- DirectDraw object creation and destruction (versions 1 to 7)
- Display mode enumeration and switching (with emulated mode switching)
- Fullscreen and windowed modes.
- Basic Blt() functionality
- 8-bit color emulated with GLSL shader
What partially works:
- 3D graphics are only partially supported.
What doesn't work:
- Many functions are stubbed out and return an error
