Are there more example songs out there that use this format?

Also a bit more documentation regarding the format would be useful, there's no info regarding supported commands and what they do or sample formats in the text file you've linked.

Hi StarWolf3000, I've attached a zip file containing modules from a few games. Please focus the Toki songs as they're pretty simple (the first one, puma.toki1, is only a 23 seconds looping song).
Also here's a file with the source code of PumaTracker (Amiga assembly) and word-file which is the documentation including supported commands. I also converted the word file to a text file.

This should help a bit. Maybe someone can progress so far that I can rip at least the samples. :)

Oh, my little request is still living and maybe almost fulfilled? :)

It's making progress. The format is quite tricky (as the small filesize might indicate), using some scripted synth instruments - but it's a good excuse to finally add that feature to OpenMPT as it is helpful for other formats like OctaMED as well.

Implemented in r20583. Note that PumaTracker instruments use a tiny scripting language, which allows sample pitch, volume and waveforms to change on the fly. This is not visualized anywhere in the OpenMPT GUI.
