SCUMM was the engine LucasArts games such as Sam & Max Hit The Road and 
Day Of The Tentacle used to store and run the games from. This is a 
utility (a perl script, of all things) that will break all the sound 
resources out of one, and store them in individual files.

To use it, get the file MONSTER.SOU from the CD, and put it in a 
directory.  Run the perl script.  Wait a while.  The sounds will be in a 
folder called "extract" in the same directory as MONSTER.SOU.

There's some interesting work being done in the realm of SCUMM emulators 
and file extraction by some guys who like these games more than even me.  
It's called ScummVM, works under Linux and Windows, and is here:  
http://sourceforge.net/projects/scummvm/

The sources gave me good information.  Check out descumm in the CVS 
directory there.

I may write a script to extract the MIDI files, too, but haven't yet.
