That's the way Gerard Putter's A2V2 (an ADT derivative) works when it
builds a format of his own making that Virtual ][ reads.  I have that
analyzer code in the ADTPro server in hopes of producing .NIBs, but I
haven't had a lot of luck creating .NIBs (or A2V2s) that actually work
in practice.  So I've kind of abandoned that line of reasoning for
now, but coming up with the right format (coupled with support from
our favorite emulators) is a good goal.
