Notes:
- The sprite Y size control is slightly different from gaiden/wildfang to
  raiga. In the first two, size X and Y change together, while in the latter
  they are changed independently. This is handled with a variable set in
  DRIVER_INIT, but it might also be a selectable hardware feature, since
  the two extra bits used by raiga are perfectly merged with the rest.
  Raiga also uses more sprites than the others, but there's no way to tell
  if hardware is more powerful or the extra sprites were just not needed
  in the earlier games.

- The hardware supports blending sprites and background.
  There are 3 copies of the palette;
  - one for pixels that aren't blended
  - one for pixels that are behind the object that will be blended
  - one for the object that will be blended
  Blending is performed by switching to the appropriate palettes for the
  pixels behind the blended object and the object itself, and then adding
  the RGB values.

todo:

- make sure all of the protection accesses in raiga are handled correctly.
- work out how lower priority sprites are affected by blended sprites.

Raiga Protection
MCU read routine is at D9CE

startup codes

it reads 00/36/0e/11/33/34/2d, fetching some code copied to RAM,
and a value which is used as an offset to point to the code in RAM.
19/12/31/28 are read repeatedly, from the interrupt, and the returned
value chanes, some kind of mode set command?

level codes

00 | score screen after level 1 (5457)
01 | score screen after level 2 (494e)
02 | score screen after level 3 (5f4b)
03 | score screen after level 4 (4149)
04 | score screen after level 5 (5345)
05 | score screen after level 6 + first loop end sequence (525f)
06 | score screen after second loop level 1 (4d49)
07 | score screen after second loop level 2 (5941)
08 | score screen after second loop level 3 (5241)
09 | score screen after second loop level 4 (5349)
0a | score screen after second loop level 5 (4d4f)
0b | score screen after second loop level 6 + final end sequence (4a49)


other game codes

13 | Game over (594f)
15 | at the start of second level attract mode (4e75)
1c | start of level 4 attract mode (4e75)
1e | after continue .. (5349)
23 | after entering hi-score (4e75)
25 | after attract level 1 (4849)
2b | after japan / wdud screen, to get back to 'tecmo presents' (524f)

also bonus life + when the boss appears but I think they use the
same commands as some of the above
