/*
    System 16 / 18 bootlegs

    Sega's System 16 and System 18 hardware was heavily bootlegged.

    Most of these bootlegs had significant modifications compared to the real hardware.
    They still roughly reflect which system they have been bootlegged from however.


    Bootlegs

    Type 16B:
    --------

    Encrypted / Protected bootlegs
     - Bay Route (set 1)
     - Golden Axe (set 1)

    These share a common encryption, Bay Route is also proteceted, the Golden Axe set has a strange
    unknown rom, maybe it's related to an MCU that isn't present on the GA board?

    ---

    Datsu bootlegs
     - Bay Route (set 2)
     - Flash Point (2 sets)
     - Dynamite Dux
     - Tough Turf

    The tilemap page select writes have been split across 4 8-bit registers on these

    ---

    Other bootegs
     - Tetris
     - E-Swat

    These appear to be a variation no the encrypted / protected bootlegs, but without the encryption
    or protection

    - Golden Axe (set 2)

    Unique bootleg, tilemap paging is split across 8 registers, bits are inverted etc.

    ---

    Type 16A:
    ---------

    Shinobi
    Passing Shot (2 sets)
    Wonderboy 3

    System 18 (more commplex tilemaps)
    ----------------------------------

    Alien Storm
    Shadow Dancer
    Moonwalker



    AMT Games
    ---------

    these aren't strictly bootlegs, but are clearly based on bootleg Tetris hardware with additional protection
    - Beauty Block
    - IQ Pipe



    ToDo
    ----

    Fully fix the tilemap banking and scrolling for all sets
    Fix sprites (and check for bad roms)
    Add support for custom sound HW used by the various bootlegs
    Look at the system18 bootlegs

    Partially Done
    --------------

    Strip out old hacks & obsolete comments (many related to the *original* system16/18 sets which have their own
    driver now)

    Sound hardware for Shadow Dancer (Datsu bootleg)

    Z80 memory map
    0000-7FFF : ROM (fixed)
    8000-BFFF : ROM (banked)
    C000-C007 : ?
    C400      : Sound command (r/o)
    C800      : MSM5205 sample data output (w/o)
    CC00-CC03 : YM3438 #1

    D400      : ROM bank control (w/o)
    DF00-DFFF : ?
    E000-FFFF : Work RAM

    The unused memory locations and I/O port access seem to be remnants of the original code that were not patched out:

    - Program accesses RF5C68A channel registes at $C000-$C007
    - Program clears RF5C68A wave memory at $DF00-$DFFF
    - Program writes to port $A0 to access sound ROM banking control latch
    - Program reads port $C0 to access sound command

    Interrupts

    IRQ = Triggered when 68000 writes sound command. Z80 reads from $C400.
    NMI = Triggered when second nibble of sample data has been output to the MSM5205.
          Program copies sample data from ROM bank to the MSM5205 sample data buffer at $C800.

    ROM banking seems correct.
    It doesn't look like there's a way to reset the MSM5205, unless that's related to bit 7 of the
    ROM bank control register.
    MSM5205 clock speed hasn't been confirmed.

    Shadow Dancer (Bootleg)

    This seems to be a modified version of shdancer. It has no warning screen, displays English text during the
    attract sequence, and has a 2P input test. The 'Sega' copyright text was changed to 'Datsu', and their
    logo is missing.

    Access to the configuration registers, I/O chip, and VDP are done even though it's likely none of this hardware
    exists in the bootleg. For example:

    - Most I/O port access has been redirected to new addresses.
    - Z80 sound command has been redirected to a new address.
    - The tilebank routine which saves the bank value in VDP VRAM has a form of protection has been modified to store
      the tilebank value directly to $E4001F.
    - Implementing screen blanking control via $E4001D leaves the screen blanked at the wrong times (after coin-up).

    This is probably due to unmodified parts of the original code accessing these components, which would be ignored
    on the bootleg hardware. Both the I/O chip and VDP are supported in this driver, just as I don't know for certain
    how much of either are present on the real board.

    Bootleg specific addresses:

    C40001 = DIP switch #1
    C40003 = DIP switch #2
    C40007 = Z80 sound command
    C41001 = Service input
    C41003 = Player 1 input
    C41005 = Player 2 input
    C44000 = Has 'clr.w' done after setting tile bank in $E4000F.
    C460xx = Extra video hardware controls

    Here are the I/O chip addresses accessed:

    E40001 = Player 1
    E40007 = Miscellaneous outputs (coin control, etc.)
    E4000F = Tile bank
    E4001D = CNT2-0 pin output state
    E4001F = I/O chip port direction
