---------------------------------------------------------------------------

- In shocking, service mode just shows the menu, with mangled graphics
  (sprites, but the charset they used is in the tiles ROMs!).
  In magicbub they used color 0 for tiles (all blacks, so you can't see
  most of it!). Again, color 0 for sprites would be ok. Some kind
  of sprites-tiles swapping, or unfinished leftovers?

- Screen flipping: not used!?

- Are priorities correct?

U67, 68, 69, 70 --------27c040
U32, 33   ------------27c020

U143, 131  .........most likely sound
U32, 33 .............most likely program
U20-23........most likely sprites
U67-70 ..........most likely BG

A1020b is close to U67-70

68HC000 p16 is close to  U32,33

16.000000 MHz

Sound section uses "KS8001" and "KS8002" and SMD --> Z80
and SMD "AD-65"
