Uchuusen's Very Simple FM Music Player for the Sega Genesis/Megadrive

     This is a very simple program that reads a file and plays music
stored in that file... that's about the long and short of it.
It's not a music driver that plays in the background, so it probably isn't
very practical, but it's a start, i guess.

     The file format is very simple.  The only info contained in it
is the note to be played and Key ON/Key OFF commands.  I might
expand the format later but for now this works to my satisfaction.
Currently there is no tracker, sequencer, or whatever to create these files,
so one must use a hex editor to make them.  For that reason, the example
music file is only 2 measures long (it sure was a pain to make).
