Are there any programs out there which can handle "raw" encoded data, rather
than just generating a d64 file? Is there any kind of standard file format for
this? The D64 format is rather limited. Ideally, I would like to be able to
read all my original (protected) disks into files for safe-keeping.

There is a disk copy program on the Vorpal disk which (I assume; I don't have
the documentation) allows disks with Vorpal-format files to be copied. But I
tried using this to copy the master disk, and the copy did not work.
