/* raiden 2 board test note 17/04/08 (based on test by dox)

 rom banking is at 6c9, bit 0x80
  -- the game only writes this directly at startup, must be written indirectly by
     one of the protection commands? or mirrored?
  value of 0x80 puts 0x00000-0x1ffff at 0x20000 - 0x3ffff
  value of 0x00 puts 0x20000-0x3ffff at 0x20000 - 0x3ffff

Games on this PCB / Similar PCBs
 Raiden 2
 Raiden DX
 Zero Team

 + varients

Some of these games were also released on updated PCBs
which usually featured vastly inferior sound hardware
 (see the V33 based version of Raiden II/DX New)


Protection Notes:
 These games use the 2nd (and 3rd) generation of Seibu's 'COP' protection,
 utilizing the external 'COPX_D2' and 'COPX_D3' lookup roms (probably for
 math operations)  These chips, marked (c)1992 RISE Corp. are not thought
 to be the actual MCU which is probably internal to one of the Seibu
 customs.

 The games in legionna.c use the same protection chips.

Current Problem(s) - in order of priority

 High Priority

 ROM banking - we don't know where the ROM bank registers are, this causes
 serious problems as it's hard to see which glitches are caused by
 protection, and which are caused by a lack of ROM banking.

 Protection - it isn't emulated, until it is the games will never work.

 Sprite Encryption - this is 99% complete for Raiden 2 / DX, just a few bad
 bits remain.  No decryption support for Zero Team yet.

 Sound - the main sets should use a variant of the Seibu Sound System, with
 an extra OKI6295, currently no sound is hooked up in these sets.  The V33
 set uses weaker sound hardware which is emulated.

 Video emulation - used to be more complete than it is now, tile banking is
 currently broken.

 Low Priority

Raiden 2, Seibu License, Easy Version

According to DragonKnight Zero's excellent Raiden 2
FAQ this PCB is the easy version.

The different versions may be identified by the high score
screen. The easy version has the Raiden MK-II in colour
on a black background whereas the hard version has a sepia shot
of an ascending fighter.

The entire FAQ is available here:

Raiden DX
Seibu Kaihatsu, 1993/1996

Note! PCB seems like an updated version. It uses _entirely_ SMD technology and
is smaller than the previous hardware. I guess the game is still popular, so
Seibu re-manufactured it using newer technology to meet demand.
Previous version hardware is similar to Heated Barrel/Legionairre/Seibu Cup Soccer etc.
It's possible that the BG and OBJ ROMs from this set can be used to complete the
previous (incomplete) dump that runs on the V30 hardware, since most GFX chips are the same.

PCB ID: (C) 1996 JJ4-China-Ver2.0 SEIBU KAIHATSU INC., MADE IN JAPAN
CPU   : NEC 70136AL-16 (V33)

        Note: Most of the custom SEIBU chips are the same as the ones used on the
              previous version hardware.

      1. X - location for COPX ROM, not populated
      2. Y - location for battery, not populated
      3. NEC V30 and NEC D71011 are located on a sub board and
         the surface-mounted V30 (UPD70116) is not populated
      4. ROM7 is located in a 8M-DIP42 to 4M-DIP40 adapter and is a 27C4002 EPROM
      5. ROM8 has the top 4 pins hanging out of the DIP28 socket and is a 27C1001
