Jojo, maintainer of OpenMPT, the open source successor of the popular ModPlug Tracker, announces that the newest version 1.18 supports both PSM files (used by Jazz Jackrabbit 1) and J2B (JJ2) files.

What does this mean? Well, basically it means that you can use OpenMPT to play, edit and export the sound files included with both games. Soundtracks of both JJ1 and JJ2 have been converted to other, more accessible formats before, but those never sounded 100% like what you hear in the games. However, OpenMPT promises to play them back accurately, so that should be great news for all fans of the soundtracks. You can download version 1.18 here.

Too bad it’s a tracker, not a player :S

Why would you want a j2b and PSM player? with an tracker you can play them back accurately and also convert them mp3, edit and save them and other stuff. in a player you can only play a couple of jazz tracks.

Jgke: You can simply save the files as IT files in OpenMPT – load the file and hit the save button, no additional work is necessary. IT files can be played with many popular module players, for example XMPlay.

I’ll try this out now. I still have that old original J2B converter from the JJ site too, lol.

Not to forget we can practically make our own jj1 music.

Been waiting a long time for something like this !

This sounds really useful; great work by the OpenMPT team! Thank you!

Unfortunately it isn’t actually too accurate. Try playing Tubelectric.

Jojo on 20 Jun 2010 at 13:08

minmay: Which version of Tubelectric do you mean, JJ1 or JJ2? I cannot notice anything wrong in both tracks, but I will fix anything that can be proven to be played wrong.

minmay on 20 Jun 2010 at 18:41

JJ2. It’s actually not a great example – try Labrat. It’s not really that bad, but noticeably different from ingame and a few parts of a few songs definitely sound bad.

Jojo on 20 Jun 2010 at 19:26

Labrat is actually my favourite track from JJ2 and I have compared that one thoroughly with the ingame version – I cannot hear any differences, to be honest. If you can highlight any differences (not “i remember this sounded different in the game”, but rather “wrong note at 1:10” or whatever), please let me know.

minmay on 20 Jun 2010 at 20:02

…I think it’s just me, then. I actually can’t test the sound ingame right now because of some driver-related issues. I have a feeling that it was me changing from one set of speakers to another that made the songs sound different.

Sorry to cause all the trouble…

Jojo on 20 Jun 2010 at 20:04

Well, it’s also possible that you used different interpolation settings in the game or something, but that does not really count as “doesn’t sound the same” – wrong notes, pattern or whatever do count, however, and I’m glad about bug reports that point out such errors.

Minmay:
Jazz2 has one of the most horrid sound systems in existence. No wonder it could sound different…

Sounds like a neat prog! Just DL’ed it.

Awesome new version of Modplug. Pretty much all of the original J2B soundtracks work as far as I can tell (Labrat and Tubelectric work perfectly for me). Although, playing through some other files with the .j2b extension, I noticed that it doesn’t use any intruments, and uses “note cut” instead of using “note off,” which can be rather noticable if you’re playing something like “Dreamland.j2b”. Seeing that they’re not original JJ2 soundtracks though, it’s no big problem. Anyway, looking forward to making some new songs with it:)

As said on a forum, I didn’t know that there were any custom J2Bs with instruments, but that is being worked on right now. Took me some evenings to reverse-engineer the instrument formats of both the new and the old J2B format (cvtj2b2it luckily spared me a lot of work on the new format), but I think I pretty much deciphered it now and those files play just fine.
