Custom ICs:
----------
04XX     sprite address generator
11XX     gfx data shifter and mixer (16-bit in, 4-bit out)
12XX     sprite generator
13XX     dual scrolling tilemap address generator
98XX     lamp/coin output
99XX     sound volume
CUS27    clock divider
CUS29    sprite line buffer and sprite/tilemap mixer
CUS30    sound control
CUS34A   address decoder
CUS36    dual tilemap generator
CUS60    MCU (63701) aka 60A1


Memory map
----------
Part of the address decoding is done by a custom IC (CUS34A), so the memory
map is inferred by program behaviour. The CUS34A also handles internally the
main and sub irq, some latches, and a watchdog.
Also, most of the address decoding for the MCU is done by CUS30.

Notes:
-----
- Is there a service mode Easter egg? Maybe with this game they stopped putting
  them in, because I haven't found them in the later games either (skykid,
  drgnbstr, etc.)

- Sprites cover the top and bottom non-scrolling portions of the fg. This
  includes the cookie cut light in round 19, which makes text disappear from
  those areas. This looks odd, but it's the correct behaviour verified on the
  real hardware.
