/* Seibu 'COP' (co-processor)  protection

  there appear to be 3 revisions of this protection (based on the external rom)

  COPX-D1 - Seibu Cup Soccer / Olympic Soccer '92
          - Legionnaire
  COPX-D2 - Heated Barrel
          - Godzilla
          - SD Gundam Sangokushi Rainbow Tairiku Senki
          - Denjin Makai
          - Raiden 2
          - Raiden DX
          - Zero Team
  COPX-D3 - Raiden 2/DX New (V33 PCB version)
          - New Zero Team

  COPX / COPX-D2 based games appear to function in a similar way to each other
  while the games using COPX-D3 appears to access the protection device very
  differently to the others.

  As this is only the external rom it isn't confirmed that the actual protection
  devices are identical even where the external rom matches.

  Protection features include BCD math protection, 'command sequences', DMA.
  memory clearing etc.

  it is not confirmed which custom Seibu chip contains the actual co-processor,
  nor if the co-processor is a real MCU with internal code, or a custom designed
  'blitter' like device.

  I suspect that for the earlier games it's part of the COP300 or COP1000 chips,
  for the COPX-D3 based games it's probably inside the system controller SEI333

  the external COP rom is probably used as a lookup for maths operations.

  there should probably only be a single cop2_r / cop2_w function, the chip
  looks to be configurable via the table uploaded to
  0x432 / 0x434 / 0x438 / 0x43a / 0x43c, with 'macro' commands triggered via
  writes to 0x500.

  this simulation is incomplete

  COP TODO list:
  - collision detection, hitbox parameter is a complete mystery;
  - collision detection, unknown usage of reads at 0x582-0x588;
  - The RNG relies on the master CPU clock cycles, but without accurate waitstate support is
    basically impossible to have a 1:1 matchup. Seibu Cup Soccer Selection for instance should show the
    first match as Germany vs. USA at twilight, right now is Spain vs. Brazil at sunset.
  - (MANY other things that needs to be listed here)

  Protection information

ALL games using COPX-D/D2 upload a series of command tables, using the following upload pattern.
This happens ONCE at startup.

Each table is 8 words long, and the table upload offsets aren't always in sequential order, as
you can see from this example (cupsocs) it uploads in the following order

00 - 07, 08 - 0f, 10 - 17, 18 - 1f, 28 - 2f, 60 - 67, 80 - 87, 88 - 8f
90 - 97, 98 - 9f, 20 - 27, 30 - 37, 38 - 3f, 40 - 47, 48 - 4f, 68 - 6f
c0 - c7, a0 - a7, a8 - af, b0 - b7, b8 - bf, c8 - cf, d0 - d7, d8 - df
e0 - e7, e8 - ef, 50 - 57, 58 - 5f, 78 - 7f, f0 - f7

table data is never overwritten, and in this case no data is uploaded
in the 70-77 or f8 - ff region.

It is assumed that the data written before each part of the table is associated
with that table.

as you can see, there are a lot of command 'command lists' between the games.
(todo, comment ones which seem to have a known function)

executing these seems to cause various operations to occur, be it memory transfer, collision checking, or movement checking.

each 12-bit entry in the tables is probably some kind of 'opcode' which runs and processes data placed in registers / memory.

If we rearrange these tables a bit, so that we can see which are common between games we get the following, take note of
the ones with slight changes, these could be important to figuring out how this works!

typically the games write data for use with the commands at MCUBASE+0xa0 - 0xaf  and MCUBASE+0xc0 - 0xcf before triggering
the operation by writing to MCUBASE+0x100 (or MCUBASE+0x102) with the trigger value.  I believe the commands can change
both COP registers and system memory.

(MCUBASE typically being 0x100400 in the 68k games, and 0x400 in the v30 games)

Seibu Cup Soccer sometimes attempts to use a trigger value which wasn't defined in the table, I don't know what should
happen in that case!

----

Protection Part 2: BCD Maths

some additional registers serve as a math box type device, converting numbers + other functions.  Godzilla seems to use
this for a protection check, other games (Denjin Makai, Raiden 2) use it for scoring:

----

Protection Part 3: Private Buffer DMA + RAM Clear
(todo, expand on this)

address ranges can be specified which allows DMA Fill / Clear operations to be performed, as well as transfering
tilemap+palette data to private buffers for rendering.  If you don't use these nothing gets updated on the real
hardware!.  These don't currently make much sense because the hardware specifies ranges which aren't mapped, or
contain nothing.  It's possible the original hardware has mirroring which this function relies on.

the DMA to private buffer operations are currently ignored due to
if ((cop_dma_trigger==0x14) || (cop_dma_trigger==0x15)) return;

----

Other Protections?

Denjin Makai seems to rely on a byteswapped mirror to write the palette.
Various other ports go through the COP area, and get mapped to inputs / sounds / video registers, this adds to
the confusion and makes it less clear what is / isn't protection related

---- ---- ---- -xxx Channel #

- channels 0x4 and 0x5 are always used to transfer respectively the VRAM and the palette data to the private buffers.
  It isn't know at current stage if it's just a design choice or they are dedicated DMAs.

- Some games (Heated Barrel start-up menu, Olympic Soccer '92 OBJ test) sets up the layer clearance in the midst of the
  frame interval. It might indicate that it delays those DMAs inside the buffers at vblank time.

- Raiden 2 / Raiden DX sets 0x14 with DST = 0xfffe and size as a sprite limit behaviour. The former is probably used to change the
  order of the loaded tables (they are the only known cases where spriteram is smallest address-wise).

- Reading here is probably used for DMA status of the individual channels or just for read-back of the register, but nothing seems to rely
  on it so far so nothing is really known about it.

0x6fc
???? ???? ???? ???? triggers DMA loaded in registers, value looks meaningless
