This patch upgrades Jazz Jackrabbit 2 for Mac to version 1.2.8. This is ONLY for Macs. I’m fairly sure that this isn’t anywhere else on J2O, but it might be fairly useful to some. If I’m mistaken, or there’s some other reason that it shouldn’t be here, please take it off. Mac-only cheats. These cheats only work in the Apple Macintosh version of Jazz Jackrabbit 2. JJD – Kills the player, like JJK or JJKILL in the Windows version. JJT – The player can chat with this cheat. It works like pressing the T button in the Windows version.
# Introduction
Jazz² Resurrection is reimplementation of the game Jazz Jackrabbit 2 released in 1998. Supports various versions of the game (Shareware Demo, Holiday Hare '98, The Secret Files and Christmas Chronicles). Also, it partially supports some features of JJ2+ extension and MLLE.
Jazz² Resurrection supports various versions of the original game, but it is recommended to use The Secret Files. Also, if you have more than one version, you can import all of them, but it's recommended to import The Secret Files as the last one. If you don't have any JJ2 version, you can run Import.exe by double-click (without parameters) and it will download and import Shareware Demo.
This project is hosted at GitHub.com/deathkiller/jazz2 and uses parts of Duality - A 2D GameDev Framework.
# Downloads

Windows
- Open the solution in Microsoft Visual Studio 2019 (or newer) and build it
- Copy
/Packages/AdamsLair.OpenTK.x.y.z/lib/OpenTK.dll.configto/Jazz2/Bin/Debug/OpenTK.dll.config - Copy dependencies to
/Jazz2/Bin/Debug/or/Jazz2/Bin/Release/ - If you build Release configuration, you have to replace
DebugwithReleasein paths above
Linux
- Install Mono 5.0 (or newer)
- Run
msbuildin directory with the solution file (.sln): - Copy
/Packages/AdamsLair.OpenTK.x.y.z/lib/OpenTK.dll.configto/Jazz2/Bin/Debug/OpenTK.dll.config - Obtain and copy
libopenmpt.soto/Jazz2/Bin/Debug/libopenmpt.soto enable music playback - Then you can rebuild the solution only with
msbuildcommand - Use
msbuild /p:Configuration=Releaseto build Release configuration, you have to replaceDebugwithReleasein paths above
macOS
- Install Mono 5.0 (or newer)
- Open the solution in Microsoft Visual Studio for Mac and build it

Jazz2.Wasmproject - Dependencies are already included for common configurations
# Extensions
Jazz Jackrabbit 2 Download Mac Os X
OpenGL ES 2.0 (Experimental)
Alternative OpenGL ES 2.0 backend can be built separately. It does not contain all featuresthat are available in default OpenGL 2.1 backend, but it should run faster on low-end configurations.Don't use it if you have no reason to do so!
To use it, build Extensions/Es20Backend project. The library will be copied to/Jazz2/Bin/Debug/Extensions/Es20Backend.core.dll automatically.Then copy all files from Content/_ES20 directory to /Jazz2/Bin/Debug/Content and replace them.
Also, you have to remove /Jazz2/Bin/Debug/Extensions/GL21Backend.core.dll file to disable default OpenGL 2.1 backend.
