  Are they in any specific order like rom page 1 is
$4000-7fff, 2 is $8000-$bfff, 3 is $4000-7fff, ect...
or they ordered different?  This would seem the most
logical.

 Do you mean a 83 specific?  If not why? I wouldn't
really think so, z80 is z80.

  Ya I've already been this route, I just wanted to do
something new. I was writing a dissassembler and say
'Hey why not dis the rom?'.  The dissassembler works
pretty flawlessly with a few exceptions, so the rom
really shouldn't be a big problem, I just have to cut
up the rom image and do the different pages seperately
to advoid the address conflicts.
