OpenJazz - http://www.alister.eu/jazz/oj/
is a free, open-source version of the classic Jazz Jackrabbit™ games.
OpenJazz can be compiled on a wide range of operating systems, including Windows, macOS, GNU/Linux and *BSD.
To play, you will need the files from one of the original games.
With the demise of DOS-based operating systems, it has become necessary to use emulators to play old DOS games. Jazz Jackrabbit™ deserves more - and would benefit greatly from new features.
is a PC platform game. Produced by Epic Games (then Epic MegaGames), it was first released in 1994. The fast-paced, colourful gameplay proved popular, and the game won PC Format's Arcade Game of the Year award. Many people still fondly recall the shareware versions.
OpenJazz was started on the 23rd of August, 2005, by Alister Thomson. Academic pressures put the project on hold until late December 2005. The source code was released on the 25th, and the first version with a degree of playability was released on the 15th of January. Since then, a variety of ports have been released by other people.
More academic pressures meant there were few updates over the following few years, but in 2009 a multiplayer version was released.
OpenJazz is available under the GNU General Public License version 2 or later,

You will need the SDL 1.2.x library (https://libsdl.org/).
For network play, you need a platform which provides sockets or use the SDL_net
library (https://www.libsdl.org/projects/SDL_net/), then either define
USE_SOCKETS
or USE_SDL_NET
in the Makefile. On the Windows platform, the
socket library (-lws2_32
) is needed.
For music support, you need to define USE_MODPLUG
in the Makefile and the
Modplug library (http://modplug-xmms.sourceforge.net/). This library needs to
be patched to support looping tracks, otherwise half of the level will be
silent. Alternatively, the xmp library (http://xmp.sourceforge.net/) may be
used, then define USE_XMP
in the Makefile. This does not need patching.
