About
GLSpeed is a remake and expansion pack of the DOS racing game Speed Haste, built on the Doom (id Tech 1) engine with OpenGL rendering, high screen resolutions, an uncapped framerate, a textured automap, and support for FLAC/OGG sound effects and MOD/S3M/IT/XM tracker music. It requires the 'speedh.jcl' file from the original DOS game to run.
How it differs from the original
It adds content not in the original DOS game, including an expansion pack of additional tracks, an in-game console for commands, configurable key bindings and screen resolution, and PascalScript-based scripting for custom content creation via Doom editing utilities.
Getting started
You'll need the 'speedh.jcl' file from the original DOS release to run it. Precompiled Windows builds are available for download, and the game includes an in-game menu for configuring gameplay, key bindings, and screen resolution.
