/***************************************************************************

Taito Triple Screen Games
=========================

Ninja Warriors (c) 1987 Taito
Darius 2       (c) 1989 Taito

David Graves

(this is based on the F2 driver by Bryan McPhail, Brad Oliver, Andrew Prime,
Nicola Salmoria. Thanks to Richard Bush and the Raine team, whose open
source was very helpful in many areas particularly the sprites.)

                *****

The triple screen games operate on hardware with various similarities to
the Taito F2 system, as they share some custom ics e.g. the TC0100SCN.

According to Sixtoe: "The multi-monitor systems had 2 or 3 13" screens;
one in the middle facing the player, and the other 1 or 2 on either side
mounted below and facing directly up reflecting off special semi-reflecting
mirrors, with about 1" of the graphics being overlapped on each screen.
This was the only way to get uninterrupted screens and to be able to see
through both ways. Otherwise you`d have the monitors' edges visible.
You can tell if your arcade has been cheap (like one near me) when you
look at the screens and can see black triangles on the left or right, this
means they bought ordinary mirrors and you can't see through them the
wrong way, as the semi-reflecting mirrors were extremely expensive."

For each screen the games have 3 separate layers of graphics:- one
128x64 tiled scrolling background plane of 8x8 tiles, a similar
foreground plane, and a 128x32 text plane with character definitions
held in ram.

Writing to the first TC0100SCN "writes through" to the two subsidiary
chips so that all three have identical contents. The subsidiary ones are
only addressed individually during initial memory checks, I think. (?)

There is a single sprite plane which covers all 3 screens.
The sprites are 16x16 and are not zoomable.

Twin 68000 processors are used; both have access to sprite ram and
the tilemap areas, and they communicate via 64K of shared ram.

Sound is dealt with by a Z80 controlling a YM2610. Sound commands
are written to the Z80 by the 68000 (the same as in Taito F2 games).


Tilemaps
========

TC0100SCN has tilemaps twice as wide as usual. The two BG tilemaps take
up twice the usual space, $8000 bytes each. The text tilemap takes up
the usual space, because its height is halved.

The triple palette generator (one for each screen) is probably just a
result of the way the hardware works: the colors in each are the same.

Stephh's notes (based on the game M68000 code and some tests) :

1) 'ninjaw*'

  - Region stored at 0x01fffe.w
  - Sets :
      * 'ninjaw' : region = 0x0003
      * 'ninjawj' : region = 0x0000
  - Coinage relies on the region (code at 0x0013bc) :
      * 0x0000 (Japan), 0x0001 (?) and 0x0002 (US) use TAITO_COINAGE_JAPAN_OLD
      * 0x0003 (World) and 0x0004 (licenced to xxx) use TAITO_COINAGE_WORLD
  - Notice screen only if region = 0x0000
  - According to the manual, DSWB bit 6 determines continue pricing :

    PORT_DIPNAME( 0x40, 0x00, DEF_STR( Continue_Price ) ) PORT_DIPLOCATION("SW2:7")
    PORT_DIPSETTING(    0x40, DEF_STR( 1C_1C ) )
    PORT_DIPSETTING(    0x00, "Same as Start" )

    However, many conditions are required to make it work due to code at 0x001404 :
      * region must not be 0x0000
      * coinage must be the same for both slots
      * coinage must be 2C_1C
    This is why this Dip Switch has NO effect in the sets we have :
      * 'ninjaw' : coinage is always different for the 2 slots
      * 'ninjawj' : region = 0x0000


2) 'darius2'

  - Region stored at 0x03fffe.w
  - Sets :
      * 'darius2' : region = 0x0001
  - Coinage relies on the region (code at 0x00f37a) :
      * 0x0000 (?), 0x0001 (Japan) and 0x0002 (US) use TAITO_COINAGE_JAPAN_OLD
      * 0x0002 (US, licenced to ROMSTAR) uses slighlty different TAITO_COINAGE_US :
        4C_3C instead of 4C_1C, same other settings otherwise
      * 0x0003 (World) uses TAITO_COINAGE_WORLD
  - Texts and game name rely on the region :
      * 0x0001 : some texts in Japanese - game name is "Darius II"
      * other : all texts in English - game name is "Sagaia"
  - Notice screen only if region = 0x0001
  - FBI logo only if region = 0x0002
  - Japan version resets score on continue, other versions don't


TODO
====

Verify 68000 clock rates. Unknown sprite bits.


Ninjaw
------

"Subwoofer" sound filtering isn't perfect.

Some enemies slide relative to the background when they should
be standing still. High cpu interleaving doesn't help much.
