 *** STREET FIGHT hardware ***  This has been adapted from the excellent

Street Fight (c) Seibu Kaihatsu (1986)


0) GENERAL.

The game has two Z80s.
The second CPU controls the two YM2203 sound chips.
There is an OKI M5205 ADPCM chip fed directly from a ROM.
Screen resolution is 256x224 (horizontal CRT).
256 colors on screen.
128 sprites (16x16).


1) ROM CONTENTS.

SF01    Main program code (encrypted)
SF02    Main program code bank-switched? into main cpu space
SF03    Sound program code
SF04    ADPCM voice data
SF05-07 Foreground tile pixel data
SF09    Foreground map data
SF10    Foreground map/tile data
SF11-14 Background tile pixel data
SF15    Background map data
SF16    Background map/tile data
SF17    Character pixel data
SF18-21 Sprite pixel data

All ROMS are 32K except SF17 which is 8K.

Graphics format is a little messy, the 4 planes come from a bit in
the high and low nibble of each byte of a consecutive pair of roms.

All graphics are made of 16x16 (composite) tiles, each of which is composed
of 4 consecutive 8x8 tiles. In all there are 1024 composite (16x16) tiles
for each of the foreground, background and sprite layers. These can be
considered as four banks each of 256 tiles.

Text characters are defined as 8x8 tiles.


2) CPU.

The board has a single? crystal @12.000 MHz.
Both CPU clocks run at 3MHz (12/4).

The main Z80 runs in Interrupt mode 0 (IM0), the game program expects
execution of two different restart (RST) instructions.
RST 10,the main IRQ, is to be triggered each time the screen is refreshed.
RST 08 must be triggered in order to make the game work properly. I haven't
ascertained the exact frequency of this interrupt yet, though the game
appears to run at the correct speed with RST08 at 30Hz. Curiously a trace
on the interrupt pin shows two interrupts occurring at 60Hz, obviously the
VBlank interrupt followed by a second interrupt some 3.3ms later. At some
stage I'll get around to probing the data lines to find the interrupt
vector addresses.

Sound CPU runs in IM1.

The sound CPU lies idle waiting the external IRQ occurrence executing code
from $0100 to $010D.

Game code/data is directly accessible by the main CPU. There is what
appears to be some level data in the second half of sf02 that may
never be bank-switched in!?! Graphics data, ADPCM samples and level maps
are not accessed by the CPUs.

Text video RAM is situated at $D000-$D7FF.

The 68705 MCU handles the two coin inputs and drives the MSM5205 ADPCM chip.
It also appears to serve as a simple protection device. During initialization,
the main Z80 writes a special ADPCM code to the MCU and then spins in a loop.
The MCU responds by asserting the Z80's /NMI line, and thus the init process
continues. The protection ADPCM code varies between versions of each game.

3) MAIN CPU MEMORY MAP.

$0000-$7FFF R   ROM sf01 (encrypted)
$8000-$BFFF R   ROM sf02 (2 x 16k banks selected by D2 of ?)
$C000-$C1FF W   Palette RAM
$C200       R   player 1 controls hard value (negative logic)

                - b6-b0 voice number
$F800-$FFFF RW  RAM

empcity contains an NMI routine which appears to control an MSM5205.
However, it does not work properly. The NMI routine is not present in stfight.

5) COLOR RAM

The palette system is dynamic, the game can show up to 256 different
colors on screen.

Each color component (RGB) depth is 4 bits, two bytes $100 apart are used
for each color code (12 bits).

I suspect that the colors are organized in sub-palettes, since the graphics
layers are all 4 bits (16 colors) each. Each of the text/graphics layers
have 'attribute' bytes associated with them that would define the palette
usage for each character/tile.

The 16 colours at offset $C0 appear to be the text palette. This group of
colours does not appear to change throughout the game, and the lower 192
colours fade in/out independently of these 16 - consistent with observations
of the real game.

There is a related mystery with the transparency colour. For the most part
colour 15 corresponds to the transparent colour, except in a few cases.
(for some Seibu PCB types transparency is handled by bit 0x40 in the CLUT
 PROMs, but not here, unless they've been dumped incorrectly)

Notes below are for Street Fight video board only

6) TILE-BASED LAYERS

The foreground and background layers comprise static virtual layers which
are 8 screens wide and 16 screens deep. The hardware scrolls around the
layers by reading registers which are updated by software every VBlank.
The text layer is fixed and cannot scroll.

The maps that define the foreground and background layers are stored in
ROMs accessed directly by the hardware. They consist of 256 bytes for
each screen which define the tile number, and a corresponding byte in
a matching ROM which defines the tile bank and presumably palette info.

The top and bottom rows of the screen are not visible - resulting in a
256x224 viewport rather than 256 square. The layers can be individually
enabled/disabled. Inactive sprites are 'parked' at row 0.

The rom layout for the foreground and sprite tiles are as you would expect,
with the four 8x8 tiles that make a single composite tile consecutive in
address. The background tiles are interleaved for presumably some good
reason, the first two 8x8 tiles from composite tile n are followed by two
8x8 tiles from the (n+512)'th composite tile.

The map roms are similarly interleaved for the background layer only.

7) SPRITES

The sprites are mapped into RAM locations $F000-$FFFF using only the first
4 bytes from each 32-byte slice. Intervening addresses appear to be
conventional RAM. See the memory map for sprite data format.

 ****************************************************************************

TODO:
- handle transparency in text layer properly (how?)
- second bank of sf02 is this used? (probably NOT)
- stfight/empcity YM2203s should be clocked at 1.5MHz but this results in
  the sound and music being 1/3 of the pitch they should be. The game never
  writes the YM2203s' divider registers yet other games (e.g. Lock-On)
  suggest the default values are correct.
  cshootert however, sounds too high-pitched at 1.5MHz*3.
- Each version of empcity/stfight has a different protection code stored in the
  MCU (at $1D2) so each 68705 will need to be dumped.
  We currently use hacked versions of the empcityu MCU for each different set.
  Currently, the following protection codes are known:
  06 USA
  08 Japan
  09 Benelux
  0d Italy
  0f Germany
  The France version doesn't care for the protection code.

         The 0/1/2 bipolar PROMs are not used for colour.

         However, this contradicts Guru's findings: "If I short some of the pins(of 0.bpr at 7A)
         the sprite colors change, and the chip is connected to the color RAM."


Brief hardware overview:
------------------------

Main processor  - Z80 6MHz
                - 68705

GFX             - custom TC15G008AP-0048  SEI0040BU    - Toshiba CMOS Gate Array
            3 x - custom TC17G008AN-0015  SEI0020BU    - Toshiba CMOS Gate Array
                - custom TC17G005AN-0028  SEI0030BU    - Toshiba CMOS Gate Array
            3 x - custom SIPs. No ID, unusually large. - covered in epoxy, probably sprite/tile gfx data is in here

Sound processor - Z80 6MHz (5.897MHz)
            2 x - YM2203C


See airraid.cpp for notes about custom modules
