Yamato:
-------
Added temporary bg gradient (bad colors/offset).
Gradient tables are stored in two ROMs. Each table is 256 bytes
long: 128 for normal and 128 bytes for flipped screen.
Color format is direct RGB mapping of 16 bits.
Gradient table are stored in two(?) ROMs.
Each table is 256 bytes long: 128 for normal
and 128 bytes for flipped screen.
Color format is unknown - probably direct RGB
mapping of 8 or 16 (both roms) bits. Also table
selection source is unknown.
At the title screen, it's a solid dark-cyan.
During gameplay, the sky is a cyan gradient, and
the sea is a dark blue gradient. When the player
ship explodes, the sky and sea briefly turn to a
lighter cyan gradient, followed by cyan-pink for
the sky, and purple-red for the sea.

The Cannon Ball bootlegs on this Falcon (Crazy Kong) hardware
don't correctly handle the protection device found on the original
pacman hardware conversion, this causes them to crash after the
a few rounds - confirmed on an original PCB. They clearly weren't
