Taito Z System [twin 68K with optional Z80]
-------------------------------------------

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 Taito Z system has a number of similarities with the Taito F2 system,
and uses some of the same custom Taito components.

TaitoZ supports 5 separate layers of graphics - one 64x64 tiled scrolling
background plane of 8x8 tiles, a similar foreground plane, another optional
plane used for drawing a road (e.g. Chasehq), a sprite plane [with varying
properties], and a text plane with character definitions held in ram.

(Double Axle has four rather than two background planes, and they contain
32x32 16x16 tiles. This is because it uses a TC0480SCP rather than the
older TC0100SCN tilemap generator used in previous Taito Z games. The
hardware for Taito's Super Chase was a further development of this, with a
68020 for main CPU and Ensoniq sound - standard features of Taito's F3
system. Taito's F3 system superceded both Taito B and F2 systems, but the
Taito Z system was enhanced with F3 features and continued in games like
Super Chase and Under Fire up to the mid 1990s.)

Each Taito Z game used one of the following sprite systems - allowing the
use of big sprites with minimal CPU overhead [*]:

(i)  16x8 tiles aggregated through a spritemap rom into 128x128 sprites
(ii) 16x16 tiles aggregated through a spritemap rom into three sprite sizes:
      128 x 128
       64 x 128
       32 x 128
(iii) 16x8 tiles aggregated through a spritemap rom into 64x64 sprites

[* in Taito B/F2/F3 the CPU has to keep track of all the 16x16 tiles within
a big sprite]

The Z system has twin 68K CPUs which communicate via shared ram.
Typically they share $4000 bytes, but Spacegun / Dbleaxle share $10000.

The first 68000 handles screen, palette and sprites, and sometimes other
jobs [e.g. inputs; in one game it also handles the road].

The second 68000 may handle functions such as:
    (i)  inputs/dips, sound (through a YM2610) and/or
    (ii) the "road" that's in every TaitoZ game except Spacegun.

Most Z system games have a Z80 as well, which takes over sound duties.
Commands are written to it by the one of the 68000s.

The memory map for the Taito Z games is similar in outline but usually
shuffled around: some games have different i/o because of analogue
sticks, light guns, cockpit hardware etc.

Controls for this game are one wheel, one switch for shift lever (used for high gear)
and one switch each for accelerate, brake, gun and nitro.

Note that the gear is low by default and is shifted to high gear by a lever which
holds the switch closed. The lever is not self-centering or spring-loaded to go back to
low. The lever must be physically shifted back to low when required.

c78-15, an unused 256 byte rom. Perhaps this contains color
info for the road lines? Raine makes an artificial "pal map"
for the road, AFAICS.

TC0170ABT is between 68000 CPUA and the TC0140SYT. Next to
that is the Z80A, the YM2610, and the three adpcm roms.

On the graphics board we have the TC0480SCP next to its two
scr gfx roms: c78-10 & 11.

The STY object mapping rom is next to c78-25, an unused
0x10000 byte rom which compresses by 98%. To right of this
are TC0370MSO (motion objects?), then TC0300FLA.

Below c78-25 are two unused 1K roms: c84-10 and c84-11.
Below right is another unused 256 byte rom, c78-21.
(At the bottom are the 5 obj gfx roms.)

TODO Lists
==========

Add cpu idle time skip to improve speed.

Is the no-Z80 sound handling correct: some voices in Bshark
aren't that clear.

Make taitosnd cpu-independent so we can restore Z80 to CPU3.

Cockpit hardware

DIPs - e.g. coinage

Sprite zooming - dimensions may be got from the unused 64K rom
on the video board (it's in the right place for it, both with
Contcirc video chips and the chips used on later boards). These
64K roms compare as follows - makes sense as these groups
comprise the three sprite layout types used in TaitoZ games:

   Contcirc / Enforce                =IDENTICAL
   ChaseHQ / Nightstr                =IDENTICAL
   Bshark / SCI / Dblaxle / Racingb  =IDENTICAL

   Missing from Aquajack / Spacegun dumps (I would bet they are
   the same as Bshark). Can anyone dump these two along with any
   proms on the video board?


Continental Circus
------------------

Road priority incompletely understood - e.g. start barrier should
be darkening LH edge of road as well as RH edge.

The 8 level accel / brake should be possible to control with
analogue pedal. Don't think mame can do this.

Junk (?) stuff often written in high byte of sound word.

Speculative YM2610 a/b/c channel filtering as these may be
outputs to subwoofer (vibration). They sound better, anyway.


Chasehq
-------

Motor CPU: appears to be identical to one in Topspeed.

[Used to have junk sprites when you reach criminal car (the 'criminals
here' sprite): two bits above tile number are used. Are these
meaningless, or is some effect missing?]


Enforce
-------

Test mode - SHIFT: LO/HI is not understood (appears to depend on Demo
Sound DSW)

Landscape in the background can be made to scroll rapidly with DSW.
True to original?

Some layer offsets are out a little.


Battle Shark
------------

Is road on the road stages correct? Hard to tell.

Does the original have the "seeking" crosshair effect, making it a
challenge to control?


SCI
---

Road seems ok, but are the green bushes in round 1 a little too far
to the edge of the interroad verge?

Sprite frames were plotted in opposite order so flickered. Reversing
this has lost us alternate frames: probably need to buffer sprite
ram by one frame to solve this?


Night Striker
-------------

Road A/B priority problems will manifest in the choice tunnels with,
one or the other having higher priority in top and bottom halves. Can
someone provide a sequence of screenshots showing exactly what happens
at the road split point.

Strange page in test mode which lets you alter all sorts of settings,
may relate to sit-in cockpit version. Can't find a dip that disables
this.

Does a variety of writes to TC0220IOC offset 3... significant?


Aqua Jack
---------

Sprites left on screen under hiscore table. Deliberate? Or is there
a sprite disable bit somewhere.

Should road body be largely transparent as I've implemented it?

Sprite/sprite priorities often look bad. Sprites go to max size for
a frame before they explode - surely a bug.

Hangs briefly fairly often without massive cpu interleaving (500).
Keys aren't very responsive in test mode.

The problem code is this:

CPUA
$1fe02 hangs waiting for ($6002,A5) in shared ram to be zero.

CPUB
$1056 calls $11ea routine which starts by setting ($6002,A5) non-
zero. At end (after $1218 waiting for a bit from sound comm port)
it alters ($6002,A5) to zero (but this value lasts briefly!).

Unless context rapidly switches back to cpua this change is missed
because $11ea gets called again *very* rapidly at times when sounds
are being written [that's when the problem manifested].

$108a-c2 reads 0x20 bytes from unmapped area, not sure
what it's doing. Perhaps this machine had some optional
exotic input device...


Spacegun
--------

Problem with the zoomed sprites not matching up very well
when forming the background. They jerk a bit relative to
each other... probably a cpu sync thing, perhaps also some
fine-tuning required on the zoomed sprite dimension calcs.

Light gun interrupt timing arbitrary.


Double Axle
-----------

Road occasionally has incorrectly unclipped line appearing at top
(ice stage). Also road 'ghost' often remains on screen - also an
interrupt issue I presume.

Double Axle has poor sound: one ADPCM rom should be twice as long?
[In log we saw stuff like this, suggesting extra ADPCM rom needed:
YM2610: ADPCM-A end out of range: $001157ff
YM2610: ADPCM-A start out of range: $00111f00]

Various sprites go missing e.g. mountains half way through cross
country course. Fall off the ledge and crash and you will see
the explosion sprites make other mountain sprites vanish, as
though their entries in spriteram are being overwritten. (Perhaps
an int6 timing/number issue: sprites seem to be ChaseHQ2ish with
a spriteframe toggle - currently this never changes which may be
wrong.)


Racing Beat
-----------

Sprites (and main road) very wrong

CPU Interleaving
----------------

Chasehq2 needs high interleaving to have sound (not checked
since May 2001 - may have changed).

Enforce with interleave of 1 sometimes lets you take over from
the demo game when you coin up! Set to 10 seems to cure this.

Bshark needs the high cpu interleaving to run test mode.

Nightstr needs the high cpu interleaving to get through init.

Aquajack has it VERY high to cure frequent sound-related
hangs.

Dblaxle has 10 to boot up reliably but very occasionally gets
a "root cpu error" still.

Racingb inherited interleave from Dblaxle - other values not
tested!

Mostly it's the 2nd 68K which writes to road chip, so syncing
between it and the master 68K may be important. Contcirc
and ChaseHQ have interleave of only 1 - possible cause of
Contcirc road glitchiness in attract?
