Start Jazz Jackrabbit with OpenJazz

Your first launch

1. 1

   Choose a desktop build

   Windows: download openjazz-windows-mingw-x86_64.zip from release 20260301 and extract all files. Mac: get the signed Universal 2 app from Mac Source Ports. Linux: the release ZIP targets x86-64 with glibc 2.35. The openjazz-20260301.zip source archive is not a ready-to-run app.

2. 2

   Place or select the original data

   Windows: place the extracted engine files in the original game folder, or drag the game-data folder onto OpenJazz.exe. For the Mac Source Ports app, place the data in ~/Library/Application Support/OpenJazz. On Linux, data alongside the executable is a fallback; you can also pass the game directory as a command-line argument.

3. 3

   Launch and check your controls

   Run OpenJazz.exe or the Mac app; on Linux, launch OpenJazz with your game-data directory if needed. Open Setup Options to check key bindings. If data is not found, confirm that the directory contains extracted first-game files rather than a ZIP, installer or Jazz 2 data.
