Jazz2 Resurrection is an open-source reimplementation of Jazz Jackrabbit 2. It supports the Shareware Demo, Holiday Hare '98, The Secret Files and Christmas Chronicles versions, and partially supports some features of the JJ2+ extension and MLLE.

How it differs from the original

The README says it partially supports some JJ2+ extension and MLLE features.

Getting started

On Windows, install the Microsoft Visual C++ Redistributable, download the game, copy the contents of your original Jazz Jackrabbit 2 directory into the Source folder, and run the Jazz2 executable. It requires Windows 7 or newer and a GPU with OpenGL 3.3 support.

Known issues & limitations

The first startup rebuilds the cache during the intro, which cannot be skipped; intro sound effects are missing that first time.
RetroArch save states are not frame-exact; netplay, run-ahead, rewind, and reset are unsupported.

What you need to run it

Use original Jazz Jackrabbit 2 game files; copy them into the platform's Source directory.
Web play requires a browser with WebAssembly and WebGL 2.0 support.
