Michael,

    What about EDD card?  You need to capture bit by bit stream from the 
disk.  Convert a group of 8 bits into a byte.  Convert each byte into 
assembly language.  Analyze assembly code and capture important assembly 
code into DOS or ProDOS file.  Modify and add new assembly code to support 
read/write files from DOS or ProDOS.  Like Where in the world is Carmen 
Sandiego.  You don't need any tools like Copy II Plus and try to copy bit by 
bit stream.  I don't like the way how cracked Where in the World is Carmen 
Sandiedgo because of scrambled Hi-Res screen while file is loaded into 
memory.  I understand that all routines are loaded into $800 through $9FFF 
then routine starts somewhere to draw the screen on $2000.
