Double Axle custom chip info
------------------------

TC0150ROD is next to road lines gfx chip [c78-09] but also
c78-15, an unused 256 byte rom. Perhaps this contains color
info for the road lines? Raine makes an artificial "pal map"
for the road, AFAICS.

TC0170ABT is between 68000 CPUA and the TC0140SYT. Next to
that is the Z80A, the YM2610, and the three adpcm roms.

On the graphics board we have the TC0480SCP next to its two
scr gfx roms: c78-10 & 11.

The STY object mapping rom is next to c78-25, an unused
0x10000 byte rom which compresses by 98%. To right of this
are TC0370MSO (motion objects?), then TC0300FLA.

Below c78-25 are two unused 1K roms: c84-10 and c84-11.
Below right is another unused 256 byte rom, c78-21.
(At the bottom are the 5 obj gfx roms.)
