Speed Haste: 2 Open Source Clones Compared
GLSpeed is a remake and expansion pack built on the Doom (id Tech 1) engine, adding new tracks, PascalScript-based scripting, and OpenGL rendering, though it still requires the 'speedh.jcl' file from the original DOS game to run. The Speed Haste Game Source Code entry is instead the original author's own 1995-2000 DOS source release, which the author notes is unlikely to compile as-is since some pieces — including a proprietary sound library — are missing from the release.
