I've taken a fleeting look at them and they appear to be "nibble" images,
with the nibbles stored in _reverse_ order!?  There seem to be a lot of
areas that are just "residue" rather than data from the current disk, too.

I think that they encode beyond 35 tracks, and also encode half tracks.

In all, it appears to be a very ideosyncratic and wasteful format.  It might
be more useful to reverse-engineer and modify the run-time program to
use standard .dsk images.
