To give credit where it is due, the "SVD" format is actually
the Daves' format for emulated disks.  The Dave S emulator used
this format, and the Dave W format was moving that way...though
was never (as far as I know) completed.  It isn't the most
efficient format, but I don't like to re-invent things that

I think we should consider standardizing on this format, again,
even though it isn't ideal.  It has the following things going
for it:  (1) it exists and is in use, (2) the image is completely
distinguishable from other formats, such as those used to store
other machines' images (such as TRS-80 or Apple), and (3) it is
quite simple to convert to/from it.  You should see the "DMK"
format for the TRS-80...

Note that Dwight and I have had some discussions about trying
to make it easier to convert/download the different formats,
using his software solution for getting images to the H8/H89.
Hopefully (after spring cleaning and the like :-) we'll get
a chance to work on it.
