You have obviously not looked at that code.....
 
It has a (logical) "Read Sector" function, which of course only
indexes into the DSK image and copies a 256-byte block from there.
But if you replace that with a function which reads a real sector off
a real disk, then the file system parts ought to work fine if it's an
Apple DOS 3.3 disk.  Yep, I had that possibility in mind when I wrote
that code .... no I don't have any concrete plans in that direction,
but OTOH you'll never know what use your code may find.

Well, if you want to dabble with the disk at the nibble level, I guess
you don't need to worry too much about the file system..... :-)
