OpenJazz is a free, open-source version of the classic Jazz JackrabbitTM games.
OpenJazz can be compiled on a wide range of operating systems, including
Windows 98/Me/XP and Linux. To play, you will need the files from one of the
With the demise of DOS-based operating systems, it has become necessary to use
emulators to play old DOS games. Jazz JackrabbitTM deserves more - and would
benefit greatly from new features.
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.
About Jazz JackrabbitTM
Jazz JackrabbitTM is a PC platform game. Produced by Epic Games (then Epic

I want to compile it myself. What do I need to know?
You will need to link to SDL. Under Amiga, you will also need to link
If you want music, things get complicated. You'll need to link to
libmodplug - unfortunately, this is only available for Linux. And even
that will have to be modified slightly - lines 376 and 409 in sndmix.cpp
should not be commented out.
