  Written by Kenneth Lin (kenneth_lin@ai.vancouver.bc.ca)

Notes:
- This game uses two 005885 gfx chip in parallel. The unique thing about it is
  that the two 4bpp tilemaps from the two chips are merged to form a single
  8bpp tilemap.
- topgunbl is derived from a completely different version, which supports gun
  turret rotation. The copyright year is also deiffrent, but this doesn't
  necessarily mean anything.

TODO:
- The high score table colors are wrong, are there proms missing?
- Sprite lag
- Coin counters don't work correctly, because the register is overwritten by
  other routines and the coin counter bits rapidly toggle between 0 and 1.
