DXGL is currently a work-in-progress and is currently considered alpha-quality software..
See DXGL Features for detailed information.
See DXGL Changelog for release information and previous version downloads.
Also see DXGL Test Results.
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
