This is a heavily modified Quake engine that adds multiple standard (and not so standard) features to the software renderer.

• Colored lighting in 8-bit color by 15bpp or 18bpp lookup tables, supports lits
• Translucent liquids with variable-adjusted alphas, supports vis
• Fog; support for the standard FitzQuake fog command syntax and values
• Widescreen display support, with horizontal area expansion; support for 16:9, 16:10, and many more aspects
• Enhanced particle system including textured additive, modulated and alpha blended particles
• Enhanced blood effects, as well as an option to disable blood and gibs
• Coronas that occlude behind walls, sprites and models smoothly
• Sound pitches, including dynamic pitching of sound in time scaling modes
• Water refraction and reflection (DirectDraw only)
• Auto-saving
• Several weapon bobbing effects to help unstiff the player's sense of movement
• Bots
• MIDI playback
• Can load BSP28 maps (Quake 0.9 shareware versions)
• Can partially load BSP30 maps (Half-Life)
• It doesn't load any 'high definition' packs (and never will, they tarnish the game's image)

Currently it has been tested on:

• Windows 95 (eng95)
• Windows XP
• Windows 7

What I'd like to get it to working on

• DOS (regressed, will need to fix)
• Linux
• MacOS

What it currently compiles with:

• Microsoft Visual C++ 6.0
• DJGPP

Some of the terrible bugs you should be aware of:

• CD audio is regressed. It kept crashing under Windows 7 so I had to gut it for now :(
• MIDI doesn't work in DOS.
• Multiplayer is completely untested. It may not work.
• Sometimes, resizing the window will cause it to become 1x1 instantly.
• It's a bit sluggish because the new colored lighting code is not written in assembly.

Some of the things that I want:

• Skyboxes
• MD2s
• MD3s including multiple surfaces and tag extension support
• IQMs
• External TGA loading including 24-bit support
• SPR32 including alpha channel support
• MDO playback via DUMB or some other Free module player that doesn't suck (no Mikmod)
• OGG playback also via DUMB via dumb_ogg
• Model texture filtering
• The DOS version working again
• More versatile DirectDraw support, including support for 4bpp, 8bpp, and 16bpp surfaces in Windows 95
• CPU speed detection so the extensive lookup table generation is disabled by default on anything less than 500mhz
