OpenJazz is a free, open-source version of the classic Jazz Jackrabbitв„ў 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 original games. With the demise of DOS-based operating systems, it has become necessary to use emulators to play old DOS games. Jazz Jackrabbitв„ў deserves more - and would benefit greatly from new features.
