| 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.
