  | The article itself alludes to this:                   It's easy

  | arcade game boards typically have a large number of chips.
  | Why's that? It's partly technical; specific chips can be
  | connected directly to particular regions of the system's
  | hardware, like graphics or sound, which means that even though
  | it's less flexible than an all-in-one ROM, it has some
  | performance advantages too. The two chips I dumped here are
  | program code for two different CPUs: one for the 68000 CPU in
  | the system itself, and one for the ARM7 CPU in the game
  | cartridge.
