/* Air Raid (aka Cross Shooter) (c) 1987 Seibu
this driver is for the single board version on the S-0087-011A-0 PCB
for the version using a S-0086-002-B0 base PCB and separate video board see stfight.cpp
Custom Modules note:
The Air Raid / Cross Shooter PCB contains 3 custom modules.
These modules have not been dumped.
2 of these are responsible for background layer generation.
the 3rd is responsible for sprites.
Both the tile gfx data, and tilemap layout data are
contained within the background modules, none of this is
accessible by the CPU (the CPU simply provides a scroll
position)
The sprite modules contain the sprite gfx data.
The modules also contain the CLUT PROM data for their layer
which controls colours and transparency. It is likely
each module contains the equivalent logic of a SEI0010BU
in order to handle this. This means there is a possibility
that the raw data from the ROMs is not exposed on the edge
of the modules, only post-lookup data.
The above information is based off a development board
which was unfortunately stripped of all ROMs.
---
TS 01.05.2006:
- added sprites, bgmap reading and few fixes here and there
airraid and cshootere are a bit "playable" ;) without gfx
Haze's notes
- video system is very similar to darkmist.cpp
Stephh's notes (based on the game Z80 code and some tests) :
- Memory notes (100% guess) :
* There are still some writes to the ROM area, but I think it's
related to wrong interrupts and/or incomplete memory mapping.
* Reads from 0xb0?? seem to be related to sound
* Write to 0xc500 happens LOTS of time - related to scanlines ?
* Write to 0xc600 might be used to disable the interrupts and
the possible communication between CPUs (if they are 2)
* Write to 0xc700 seems to be done when a coin is inserted
(also done once during P.O.S.T. - unknown purpose here).
* Write to 0xc801 might be sort of watchdog as it "pollutes"
the error.log file.
- Inputs notes :
* COINx don't work correcly : see "cshooter_coin_r" read handler.
* In game, bits 3 and 4 of 0xc202 ("START") are tested,
while bits 4 and 5 are tested in the "test mode".
* Pressing STARTx while in game adds lives (depending on the
"Lives" Dip Switch) for player x.
- Other notes :
* 0x0006 contains the "region" stuff (value in 'cshooter' = 0xc4) :
. bits 2 and 3 determine the manufacturer :
0x00 : "J.K.H. Corp." (no logo)
0x04 : "Taito Corporation." (+ logo)
0x08 : "International Games" (+ logo)
0x0c : "Seibu Kaihatsu,Inc." (+ logo)
. bits 6 and 7 determine the title screen :
0x00 : unknown - scrambled GFX *probably air raid, haze
0x40 : unknown - scrambled GFX (alternate entry) *probably air raid, haze
0x80 : "Cross Shooter"
0xc0 : "Cross Shooter" (same as 0x80)
- Addresses :
* 0xe222 : contents of DSW1 (0xc204)
* 0xe223 : contents of DSW2 (0xc203)
* 0xe228 : difficulty (from DSW2)
* 0xe229 : bonus life (from DSW2 - table at 0x6264)
* 0xe22b : lives (from DSW2 - table at 0x7546)
* 0xe234 : credits (0x00-0xff, even if display is limited to 9)
. if 1 coin slot , total credits
. if 2 coin slots, credits for player 1
* 0xe235 : credits (0x00-0xff, even if display is limited to 9)
. if 1 coin slot , always 0x00 !
. if 2 coin slots, credits for player 2
* 0xe237 : lives for player 1
* 0xe238 : lives for player 2

/*
Custom SIMM module placement
The Air Raid PCB has 3 custom modules shown
in the rough diagram of the PCB below.
The modules do not appear to be 100%
identical based on external shapes visible.
The data they contain is as follows
MODULE1
Background tilemap graphic data
Background tilemap layout data
MODULE2
Foreground tilemap graphic data
Foreground tilemap layout data
MODULE3
Sprite graphic data
it's also possible each module contains a
0x100 colour look up table for that layer.
