Here is the music from the various versions of Moktar and Titus the Fox.
How to play them:

• PC Speaker (.BAS)
  These can be played with a DOS BASIC version like QBasic (included with W9x and the later DOSes).
  QBasic also is freely downloadable from Microsoft's web site.
• PC AdLib (.DRO)
  This patched AdPlug helps you out.
• Amiga (.MOD)
  Winamp should play these just fine.
• Atari ST (.YM)
  STSound does the trick.
• Amstrad CPC (.AY)
  Just plug NEZPlug into Winamp.

You might notice the table isn't quite complete. I haven't finished dumping all the PC AdLib files, I'll upload them when that's done.
For the other missing files; I don't have them. Of course, any contributions are welcome!
