OpenJazz is a free, open-source version of the classic Jazz Jackrabbit games. OpenJazz can be compiled on a wide range of operating systems. To play, you will need the files from one of the original games.

Release notes by jmetal88:

Hi all,

After a minor (one line) modification to Alister’s OpenJazz source code, I have the latest version running (mostly) properly on the Wiz. I have also updated the archive with the version of SDL I am using, which should eliminate tearing on screen.

The upload is still being ‘processed’ by the file archive, but once it’s ready, it should be available here (if everything goes smoothly):,0,0,0,35,128

Please note, I am not a programmer, so I don’t know how to fix the garbled-looking opening cutscene or Jazz’s stuttering steps as he runs uphill. I just got lucky figuring out the line to change to make the colors correct. I found the game to still be quite enjoyable, though, so I figured I should release it.

Improvements over the old release include the plasma-y effect on the menu screen, enemies properly exploding, and more!

EDIT: It never showed up on the archive, and I’m not sure why. Grab it here:
