This is the source for the last release of Jaymod, which is version 2.0.0.
The mod has a very powerful make system that can cross-compile the mod for Linux, Windows (via mingw) and OSX. There are also specialty binaries for specific CPU platforms for each of these platforms.
Information about the build system can be found in the build system notes.
Some of the compilation and system libraries required to make a complete build have been lost to time. If anyone would like to minimalize the build system and provide compilation instructions, it would be much appreciated.
This source is bound to the original terms from id Software. On top of that, I am releasing this source under the Apache 2.0 license. Feel free to use this codebase as you please, as long as both licenses are bundled and proper credit is given.
