libDGL
libDGL is a "retro coding" C library aimed at MS-DOS VGA Mode 13h game development. It is developed with DJGPP with 486 DX2 systems as a baseline target for performance.
Why?
Because it's fun.
If you were looking for something for "retro" MS-DOS game development that is fully featured, really performant and bug-tested that's ready right now, have a look at Allegro 3.x or possibly 4.x depending on what hardware you're targetting.
Status
This library is currently under early development and is lacking many things and probably chock-full of bugs.
Done / Mostly Done
- Primitive drawing support
- Text rendering
- Blitting
- Graphics clipping
- Keyboard input
- Mouse input
- PCX loading/saving
- Math library (general helpers, 2D vector, 3x3 matrix)
- Basic error handling / results
TODO
- Scaled/rotated blitting support
- Blending
- "Mode 7" like support
- Custom font loading (BIOS-like format?)
- Joystick / Gravis GamePad support
- PC speaker sounds
- Sound Blaster compatible sound/music
- Gravis Ultrasound compatible sound/music
- Fixed point math
- Sine/cosine lookup table optimizations
- BMP, LBM, GIF image loading (and saving?)
DJGPP Toolchain
Along the same theme as this library itself, I am using an older version of DJGPP from the late 90's. I have not tested with any other versions of the DJGPP toolchain other than:
15 Jan 1998 bnu281b.zip
24 Oct 1997 csdpmi4b.zip
31 Oct 1996 djdev201.zip
18 Jan 1997 faq210b.zip
6 Jun 1998 gcc281b.zip
18 Oct 1996 gdb416b.zip
6 Jun 1998 gpp281b.zip
1 Mar 1998 mak3761b.zip
30 Sep 1997 rhide14b.zip
This is a pretty arbitrary selection that was based on a cut-off of about 1998 (which was when I first came across DJGPP when I was younger).
