[Coco] MUSICA 2 files

[Roger Taylor]

I found the problem why my MUSICA files moved from .dsk image to 
local PC file appeared to be corrupt.  When using wimgtool.exe, some 
of the files have LF/CR processing done on them, causing bytes to be 
added here and there.  Ofcourse this causes the music either to not 
play at all, sound like a train wreck, or play for a bit then crash 
out.  I just used port.exe on a .mus file and I'm now playing the 
tune in the background of my game.

Also, first I LOADM the .mus file which almost always places the 
music data between 16384 and ... {32767 or less) and I use a custom 
BASIC program to later rewrite only that data out as a new 
file.  Some .mus files have player code preprended starting at 16128 
so when you do an EXEC, the file plays without an external 
loader/player.  I strip that out and use only the waves and notes data.
