OpenJazz
Installing OpenJazz for Windows
You will need two things:
  1. An existing installation of a Jazz Jackrabbit game - available from Haze's Hideout.
  2. OpenJazz for Windows - see the download section.
The OpenJazz files must be in the same folder as each other. You can place them in your Jazz Jackrabbit™ folder, and OpenJazz will be ready to run. You can also place them elsewhere if you use your Jazz Jackrabbit™ folder as a command-line option (e.g. by dragging and dropping it onto OpenJazz.exe).
