Preliminary driver by Mariusz Wojcieszek
Notes:
It's possible that the Moonquake set is actually a hardware diagnostic program
rather than the game itself. The origin of the set and the state of the PCB
from which it was dumped are unknown.
* There are no references to Moonquake within the entire ROM data.
* No code paths lead out of the test mode.
* The non-test-mode data starts at 0xf03c3e. Curiously, there are no FF values
within the data and large sections are repeated (see 0xf20000, 0xf40092, 0xf60023
and 0xfa0046). Initially thought to be encrypted/compressed data, it may instead
be randomly-generated data for testing the ROM banks.
* ROMs 5L/5H are not present in a photo of a known-working PCB.
* The ES5503 ROMs only contain speech for the sound bank tests.
* The external interrupt (INT6) is related to the ES5503 but appears to be unused
by the diagnostic program.
* The internal program of the I/O MCU (68705) is undumped.
