You should also be aware that many protection schemes cannot be
represented in a .nib file.  I've never seen a study of what fraction
of protected disks *can* be handled by .nib imaging, but I'm sure that
it decreases with time, since later copy protection schemes were much
more complex and could not be represented as 35 (or 36) tracks.

For these more highly protected disks, the only known way to run them
on an emulator is to de-protect (or "normalize") the disk, then image
it as a standard .dsk image.  The only method for normalizing a disk is
to do a lot of human detective work (which for many was much more
challenging than playing the game ;-).

If the program writes to the disk as well as reading from it, then
extensive changes may be necessary to adapt it to a normal format.
