Would it be difficult to give the user more control, similar to 
catweasel so that copies could be made of old protected software disks 
before they rot away.  I have never been a real lover of playing games, 
but Marty's Nightmare was probably my all-time favorite, and only a very 
few were ever made.  It is copy protected.  Many, many years ago I was 
able to make a few copies of my original disk using COPYIIPC and the 
transcopy board in an old IBM PC, but those copies will someday cease to 
work.
