/* 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

  to do:
  clean it up, consolidate code, make it work!
