Actually, the header wasn't even developed for MESS, I developed if for my
standalone 7800 emulator. I wanted to avoid the nightmare of dozens of
command line switches that many 2600 emulators had to support all the
different bankswitch modes and controller configurations.

That's correct.  The reason I don't support signing of raw binaries > 48K is
that I don't know which section of the ROM is mapped at console init time,
so I can't calculate a signature.  The A78 header has that additional meta-
information about the mapping that is needed.  There is nothing MESS-
specific about the A78 format, BTW, except that it originated with MESS.
It's actually a good solution to that mapping problem which crops up with
bank-switched cart images on all consoles.
