* Some mask ROM types are strange, PCB was no help since all ROM PCB labels say "2M - 16M". Therefore,
some types could be dumped incorrectly. If there's problems, contact me.

(1) = First & second halves identical according to ROMCMP, but it's surely not a 40 pin 2M ROM ?
(2) = Both halves were also identical according to ROMCMP, so ROM was cropped to 2M. But it could be a 2M or 4M ROM. Actual type is unknown. (see *)
