Well it's been over a year, but as some of you have noticed from the
SVN logs we now have sound properly working on the M:Robe 500 (DM320)
with our decoders!

The first mp3 that was played is Dispatch - Bullet Holes. Many thanks
to Cat for his initial work getting this setup and his pointers along
the way! There is still a good amount of work to do on the port, but
it is quite usable as it stands.
