Here's OpenJazz built using the most recent sources. You need either the shareware data files or game files from Jazz Jackrabbit 1.

The openjazz engine is not completed yet. Most noticably boss AI is not currently working. See the included manual for more details.

Installation instructions are included with the .opk file. Music is working (thanks to Zear for help with this). Network play has been tested by me and my son which has considerably delayed this release

Enjoy

UPDATE
16/08 fixed white bar issue
