Jazz Jackrabbit 2 Plus (JJ2+) adds countless features and bug fixes to both Single Player and Multiplayer gameplay within JJ2, and is used almost universally by most serious players. It has much better network code than the original game, adding console commands to online games, fixing most major game-crashing errors and connection problems, allowing permitted clients to log in as "remote administrators" in someone else's server and control the gameplay, and adding several new multiplayer gamemodes. It additionally fixes or enhances many of the events in the game, and allows level designers far more power than in regular JJ2 through the addition of an easy-to-use scripting language. JJ2+ takes everything great about JJ2 and adds so much more on top of it; it is truly a must-download. JJ2+ is distributed under the MIT license.

It's been a couple years, but JJ2+ is back in action with version 5.7. One thing you'll notice is a bunch of fixes to annoying multiplayer bugs or other issues, such as the antihack protection overzealously kicking people from servers for having sugar rushes. The code for detecting spam attempts is more robust now, and there are fixes to antiradar protection so clients don't hear weird sounds all the time. A music playback bug discouraging the use of bird or frog morphs in multiplayer games has been fixed. Player health displays are now better synced between clients and servers, a new scripting function provides greater control over HUD graphics for custom multiplayer gamemodes, and spectator mode has been updated to preview where other players are looking:

While spectating players, you can follow their shifting camera instead of having them locked to the center of your screen. Also, the game tells you what your screenshot filenames are.

Local single player games have also seen their share of improvements, including better optimization of some drawing code. Longstanding bugs in two official maps, Medieval Kineval and Suburbia Commando, have finally been remedied. The JJNOWALL cheat code has been made a bit more userfriendly. A wider variety of controllers is now supported, secret levels work a little better, and pushable objects (such as crates) got some bug fixes.

Crates are among the game objects with new fixes.

And as ever there are a raft of miscellaneous changes that may address this or that issue that's been specifically bugging somebody for a long time. The Head Hunters multiplayer gamemode has had its scoring algorithm rewritten. Some player physics glitches with wind, conveyor belts, and hooks have been fixed. Players with huge resolutions may scale the game window more freely. Better support for pasting links to websites into chat. Fixes to a few hotkeys. And so on. Download JJ2+ today!

I think it's a good time to bump it up, both JJ and JJ2 were released on GOG today.

Game of my childhood... Sure brings back memories.
Anyone knows if there's a site where I can download the extended versions of the music from the game? Not a simple loop, but one the starts at the right moment to properly connect to the end of the track.

Try deleting your .cfg files so that they can be restored to their defaults.

Latest patch is giving me a "divide by zero" error whenever I complete a single player episode.
