/* Final Crash & other CPS1 bootlegs */


/*
    A note regarding other bootlegs:
    In order to keep the cps source in some sort of order, the idea is to group similar bootleg hardware into seperate
    derived classes and source files.

    Rom swaps, hacks etc.  (on original Capcom hardware)  ->  cps1.cpp
    Sound: Z80, 2x YM2203, 2x m5205 ("Final Crash" h/w)   ->  fcrash.cpp
    Sound: Z80, 1x YM2151, 2x m5205                       ->  cps1bl_5205.cpp
    Sound: PIC, 1x M6295            *1                    ->  cps1bl_pic.cpp
    Sound: Z80, 1x YM2151, 1x M6295 *2                    ->  fcrash.cpp      (for now...)

    *1 these seem to be only CPS1.5/Q sound games?
    *2 this is original configuration, but non-Capcom (usually single-board) hardware.

    As per the above, this file now only contains games in second and last catergories.
    Eventually only Final Crash, other Final Fight bootlegs and Carrier Air Wing bootlegs will remain here.

/*

Final Crash is a bootleg of Final Fight

Final Fight is by Capcom and runs on CPS1 hardware
The bootleg was manufactured by Playmark of Italy

this driver depends heavily on cps1.cpp, but has been
kept apart in an attempt to keep cps1.cpp clutter free

Sound is very different from CPS1.

Final Crash (bootleg of final fight)

1x 68k
1x z80
2x ym2203
2x oki5205
1x osc 10mhz
1x osc 24mhz

EPROMs:
1.bin sound EPROM
from 2.bin to 9.bin program EPROMs
10.bin to 25.bin graphics EPROMs

kodb has various graphical issues, mainly with old info not being cleared away.
Also, it should be using a vblank irq value of 4. This triggers the following bootleg read/writes;
 - IN1 is read at 0x992000
 - IN0 is read of 0x992008
 - dips continue to be read at 0x80001a
 - sound command is wrote at 0x992006
 - scroll 1Y is wrote at 0x980000
 - scroll 1X is wrote at 0x980002
 - scroll 2Y is wrote at 0x980004
 - scroll 2X is wrote at 0x980006
 - scroll 3Y is wrote at 0x980008
 - scroll 3X is wrote at 0x98000a
 - the layer enable and layer mask writes continue at 0x98000c and 0x980020-2

These read/writes are identical to those used by a Knights of the Round bootleg which uses the all sf2mdt sound
hardware. This set is currently non-working.

This also prevents the game from toggling the sprite address at m_cps_a_regs[0], similar to other bootlegs.
Currently the game is working somewhat, but only using the code left over from the original. If anyone wants to
do any development work on the set, (eg, find the sprite clearing issue), then this should be changed as the game
likely won't write any sprite clearing values otherwise.

None of this is hooked up currently due to issues with row scroll on the scroll2 layer.


Status of each game:
--------------------
cawingb2, cawingbl: OK.
fcrash, kodb:       Old sprites show on next screen. Patch used.
sf2m1:              Crowd is missing. Plane's tail comes off a bit. Patch used.
wofabl:             Old sprites left behind - doesn't seem to write end-of-table marker when sprite table is empty.
                    Priority problems - doesn't seem to write the layer mask values anywhere.
                    Incorrect layer ordering during attract - writes invalid layer order values to layer control reg (bits 6-13).
                    Glitched level 1 trees - bad data in gfx rom 12 but dump is confirmed correct.  https://youtu.be/RWKhBzwH0Gk
sgyxz:              Priority problems - doesn't seem to write the layer mask values anywhere. Patch used.
                    Missing foreground trees on level 1.
wofr1bl:            Priority problems - doesn't seem to write the layer mask values anywhere.

brightness circuity present on pcb?
    sgyxz       no
    wofabl      no
    wofr1bl     no
    others      tbc...   assume yes for now
