Once again, there's a new version of OpenJazz.

For those of you who aren't familiar it, it's an open source re-implementation of the Jazz Jackrabbit 1 engine. It needs SDL to run. Before you try to play it, put OpenJazz.exe, openjazz.000, modplug.dll and sdl.dll in your Jazz 1 directory.

As usual, this version includes a number of small improvements. But it also has a major new feature: Multiplayer.

There are currently three modes to choose from: Cooperative, Battle and Team Battle. Just like in JJ2, you can change your player's fur, bandana, gun and wristband colours. You can also press F9 to view the player list.

Multiplayer isn't working properly yet. It works locally, but so far I've been unable to get it to work over the internet. I am behind a router, though, so you may have more luck.

Enjoy!

Sounds awesome. Who wants to try it out with me? I'm most certain I'm not behind a router.

I've edited my OpenJazz for Mac OS X package in the J2O downloads to this latest version. I also got sound working! Mac users rejoice!

It's pretty sweet! I even got it to run on Vista64, but I had to install the jj1 cd through Dosbox. Can't wait to see if we can get multiplayer working.

well you might try hamachi.
If you need a network i made 1 a long time ago(thought JJ1 will some day have MP and i was right :P).

Name: JJ1Server
Pass:No password

I tried multiplayer over hamachi a few days ago, but was unable to connect, or have others on the network join. Not sure if its just me, but I'm guess even with Hamachi, we may have to wait until the next update.

There's a new version up now. I've made some changes which should hopefully help.

Yet another new update for Mac in the J2O downloads section.

I just played the PC version online. It actually works! Althogh there are some serious bugs. For example, dying can cause the screen to black out, and stay that way.

yes. And I expected that the hoverboard doesnt work.. I excepted a strange bug there, as soon I hit the hoverboard, it works.. only the board dissapears

I just tried a LAN game of OpenJazz for Mac, and it was awesome. All it needs is a CTF mode. And a JJ1 Semi CTF conversion.

Also, good work on adding sound, Ricerind.

Thanks! It was actually far easier than I'd anticipated.

Right, there's a new version that gets rid of the blacking-out bug.

The board has always been a problem. It's not part of Jazz's hovering sprites. But if I superimposed it, it would be there when playing as the bird in Birdland.

CTF mode is tricky, because there are no flag/base sprites. Something could be used as a substitute, though. Capture the bird?

Airboard: DD's notes say that all that sprite pointer stuff is in Block 11, as in "Accessory Animations" in J1E.

capture the bird? yes man that totally wins those birds are so cute id totally want to go steal one

Would the flag-bird fly once you get shot once? Sounds like a very turtle(DEVAN SHELL)-happy game.

New Mac version available.

Very awesome. I've been secretly hoping you'd implement file storage outside of the .app.

Ok, played online again. Works quite well. However, at one point time ran out, or something, and both players died at the same time. We respawned on the checkpoint, but we couldn't move (although shooting still worked), and constantly were gaining lives.

Ya i was with troglobite....andf to add to his statement it changed his name to the same as mine and i had a bird only he could see

In the DMG you've uploaded, the READMe is missing.
Where should we put the JJ1 data files???

Thanks!

There's a new version. The time-running-out bug and the bird bug have been fixed. I couldn't reproduce the name-changing bug.

I think the name change may have been caused by something else. I'm pretty sure it wasn't caused by openjazz

This name changing bug just sounds soooo familiar.

As for the MAC version, sound/music is not working on PowerPC macs, and colors seem to be all wrong for most resolutions.
Endianess problems, I suspect...

Since version from March 22, 2009 there's been problem with defining keys of gamepad. When I'm trying to define "UP key", I got message "press control", the game does not respond, I can only press ESC; however in game, joypad works (B1-shot, B2-jump, B3-change). This problem didn't occur in previous (20090315) version (I was only unable to assign Button1).

I've noticed that sometimes jump stops working, and you have to move to a different position to be able to jump again. This appeared in the second latest version, and is quite common.

It appears that on PowerPC Macs the sound problem is unique to the music, as the sound effects in the latest version of OpenJazz work fine. The colour distortion when changing resolutions is a bug in OpenJazz in general and as far as I know it is not unique to Mac, let alone PowerPC.

Ricerind, I'd like to take this time to somewhat randomly thank you for the awesome work porting OpenJazz to the Mac platform, and always quite expediently after the official release. The Mac crowd in the JCF is very small and not too vocal (with the exception of my ranting), so it's good to see us get some support once in a while.

Thanks again.

Thanks! Speaking of which, there's another version I need to upload

I've uploaded the latest version.

New version!

The colour problem that appears when you change resolution has been fixed. I don't know what the problem with sound is. I don't get any sound in Linux, but I suspect that's just an issue with my install.

Neo2001: Oops. I made a silly mistake there. It's now fixed.

Ricerind: I've fiddled about a bit, and I think I've fixed the jumping problem. I didn't get it very often, though, so it's hard to be sure.

Okay. How is it that someone has ported this game to the Dremcast, GP2X, GP32, the Palm Pilot, the Wii and even the PSP, and yet there's not a port for the Nintendo DS yet? :P

Oh hey, defalcon!

If you know anyone who can port stuff to the DS, feel free to give them a poke!

Btw, OpenJazz is now on SourceForge (here). All contributions are welcome - from large chunks of code to niggling bug reports!

Using the nifty Program SUPER
http://www.erightsoft.com/SUPER.html
you can convert ROM's to .nds which is the DS game file. This would still leave 2 problems, making OJ into a ROM and finding a way to run it over DS without modding it (DS's are a pain to use custom content on)

Plunk: not sure that's entirely necessary...the DS has a large homebrew community, just like the other consoles.

Alister: Ah, I wish. I don't know anyone with any coding ability :P

Stijn: Hey...the name is familiar, but I'm blanking. Sorry. Did you have a prior username?

Flash/Fl@$h

Alister, you're one of the coolest organisms on this planet. Also, seeing this on the DS would be insane.

This is pretty awesome! Good job...! I havn't tried it online yet, but I'm wondering do you need to open any specific port? I tried entering "ip : port" but I couldn't enter the colon symbol... so is there any default port?

I think it's pretty amazing how you can see this huge part of the level by simply dragging the game screen all accross your screen.
