Are you saying that ALL VHD's should be one head regardless of what DD.FMT
reports? That would be an easy fix, and I can force it to always use $82 for
DD.FMT if it's a VHD if that would be the proper use.

Not sure why these images exist but for LSN0 DD.FMT (byte $10) should be
$82; hard drive one side. I'd bet your value is 3.
In any case, it makes no difference to RGBDOS in MESS or VCC and I don't
know if Walt's program does more than just report it.

You can easily change the value using ded while running NitrOS-9 or with a
PC raw file editor.
