    Driver: aristmk4

    Manufacturer: Aristocrat Leisure Industries ( aka Ainsworth Nominees P.L. )
    Platform: Aristocrat 540 Video ( MK 2.5 Video / MK IV )
    Driver by Palindrome & FraSher

    original 86lions.c driver by Chris Hardy, Angelo Salese & Roberto Fresca


    ***************** INITIALISATION *********************************************************************

    Method 1 :
    * Key in with the Jackpot Key followed by the Audit Key (F1 then F2 keys)
    * Hit UP (W key) twice (for gunnrose only)
    * Press PB4, PB5 and PB6 keys simultaneously (Z+X+C keys by default)
    * A value (displayed below) will appear next to RF/AMT on the right of the screen
    * Key out both the Jackpot and Audit Keys

    This method works with the following games:
    3bagflnz 200
    3bagflvt 200
    autmoon  200
    blkrhino 200
    cgold    500
    coralr2  200
    eforesta 200
    eforestb 200
    ffortune 200
    fvrpitch 200
    gldnpkr  400
    goldenc  200
    gtroppo  500
    kgbird   200
    kgbirda  200
    phantomp 200
    swtht2nz 200
    wildone  200
    wtigernz 200
    gunnrose N/A (no hopper to refill)

    Method 2 :
    * Key in with the Jackpot Key followed by the Audit Key
    * Press PB4, PB5 and PB6 keys simultaneously (Z+X+C keys by default)
    * This will enter the cashcade screen and increment $100 to the maximum.
    * Press PLAY 2 LINES [listed as BET 2 on the screen] to increment the minimum cashcade value by $5.
      - (optionally, you can decrement with the PLAY 1 LINE [BET 1] button, but you must first increment
        the $5 to start with above or the game won't initialise)
    * A value (displayed below) will appear on the right as RF/AMT when you key in again (not visible
       until you key out and back in again with the Audit Key)
    * Key out both the Jackpot and Audit Keys

    This method works with the following games:
    topgear  500

    Method 3 :
    * cgold2, fhunter and fhuntera ONLY: DIP labeled "5201-5" switch to ON
       This allows setup procedure to complete properly and game to play (if disabled, it acts as a
       'freeze' switch and the games don't accept inputs).
    * Key in with the Jackpot Key followed by the Audit Key.
    * Press PB4, PB5 and PB6 keys simultaneously (Z+X+C keys by default)
    * Press Service (default A) 4 times until you are in the Setup Screen, showing Printer Pay Limit etc.
    * Press Bet 2 (default D) to change the Jackpot Win Limit. A higher value is better (3000 max)
    * Key out both the Jackpot and Audit Keys

    This method works with the following games:
    arcwins
    cgold2
    eforest
    fhunter
    fhuntera

    Technical Notes:

    68B09EP Motorola Processor
    R6545AP for CRT video controller
    UPD43256BCZ-70LL for 32kb of static ram used for 3 way electronic meters / 3 way memory
    U6264A for Standard 8K x 8 bit SRAM used for video buffer
    1 x R65C21P2  PIA - Peripheral Interface Adapter, connects to RTC and sends pulses to mechanical meters
    1 x 6522 VIA - 1 x Rockwell - Versatile Interface Adapter.
    2 x WF19054 = AY3-8910 sound chips driven by the 6522 VIA
    1 x PML 2852 ( programmable logic ) used as address decoder.
    1 x PML 2852 programmed as a PIA

    PIA provides output signals to six mechanical meters.
    It also provides the real time clock DS1287 to the CPU.

    VIA drives the programmable sound generators and generates
    a timing interrupt to the CPU (M6809_FIRQ_LINE)

    The VIA uses Port A to write to the D0-D7 on the AY8910s. Port B hooks first 4 bits up to BC1/BC2/BDIR and A9 on AY1 and A8 on AY2
    The remaining 4 bits are connected to other hardware, read via the VIA.

    The AY8910 named ay1 has writes on PORT B to the ZN434 DA converter.
    The AY8910 named ay2 has writes to lamps and the light tower on Port A and B. these are implemented via the layout


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

    2 x Sound Chips connected to the 6522 VIA.

    16/05/10 - FrasheR
    Fixed VIA for good. 5010 - 501F.
    Hooked up push button inputs - FrasheR
    Hooked up ports for the PML 2852 U3 - FrasheR

    16/05/10 - Palindrome
    Lamp outputs and layout added - Palindrome
    NVRAM backup - Palindrome

    20/05/10 - Palindrome
    Connected SW7 for BGCOLOUR map select
    Added LK13. 3Mhz or 1.5 Mhz CPU speed select
    Added sound sample for mechanical meter pulse ( aristmk4.zip ).

    30/5/10 - Palindrome
    Now using mc146818 rtc driver instead of rtc_get_reg.

    The mc146818 driver has issues and is not working correctly.
    MESS developers are looking at it.

    - day of week is incorrect
    - day of month is incorrect ( code is using day instead of mday ).
    - hours are not showing up correct in PM and 12 hour mode
    - rtc causes game to freeze if the game is left in audit mode with continuous writes
       to 0xA reg - 0x80 data )

    9/7/2010 - Palindrome
    Robot Test added
    Default Jackpot key re-assigned to 'I'
    Work around for topgear & cashcade games
    Improved coininput - force CBOPT1 to detect passing coin
    Added new game Golden Poker ( Aristocrat version ) [ bad dump ]
    Added new game Gone Troppo
    Added new game Wild One
    Misc improvements

    12/12/2010 - Palindrome and Heihachi_73
    Updated source to 0.140u2 standards
    Disabled real time clock to stop games from hanging. This causes a graphics glitch
     on the month display but makes the games more reliable in audit mode.
    Fixed ROM names
    Added new game Arctic Wins
    Added new game Caribbean Gold 2 (missing 2 gfx roms, still boots)
    Added new game Clockwise (program ROM nodump, all other roms fine)
    Added new game Fortune Hunter (2 sets)

    06/06/2011 - Heihachi_73
    Added button panel artwork for all games, and renamed the in-game buttons to match
     the artwork and/or Robot Test description.
    Remapped Jackpot Key to 'L'
    Remapped 'power fail' key to ',' (comma)
    Remapped the video poker buttons; holds are now keys S,D,F,G,H
    Un-mapped the unused inputs

    06/08/2011 - FrasheR
    Implement 'Printer Fault' fix.

    08/08/2011 - FrasheR
    Implement Port '5005' for eforest. Changing this only works after performing memory reset.(delete nvram file)
    First 3 bits
    000 = $100 / Credit
    001 = 50c  / Credit
    010 = $5   / Credit
    011 = 10c  / Credit
    100 = $10  / Credit
    101 = 25c  / Credit
    110 = $1   / Credit
    111 = 5c   / Credit (default)
    Implement Bill Acceptor for eforest to add credits.
    arcwins and eforest are now working.

    21/02/2013 - Heihachi_73
    Added new game Caribbean Gold (cgold), however it is not a straight swap as it has slightly different input locations:
     - With unmodified 0.148 source, game complains about logic door being open,
        which is seemingly tied to the current coin input.
     - When HOPCO2 is toggled off/on quickly (default is on otherwise it will
        cause a note acceptor error), the note acceptor works, adding 4 credits ($1?).
        This is seemingly a quarter slot (25c). Not sure if other notes are possible.
     - Same gameplay as Gone Troppo, one interesting thing about this game is that
        the KQJ symbols have actual faces instead of plain letters. These symbols were also found on some mechanical reel slots.

    08/03/2013 - Heihachi_73
    Cleaned up comments and erroneous ROM names (e.g. graphics ROMs named after the program ROM).
    Caribbean Gold II - copied cgold graphics ROMs u8+u11 (aka u20+u45) to cgold2, game now playable.
     Tiles 0x64 and 0x65 are used to show the game's denomination (credit value), however cgold does
     not use these tiles (there are seemingly unused line/bet/number tiles in this location), this
     causes a graphics glitch on the $/cent signs.
    Promoted Fortune Hunter and clone to working status, as they were in fact working for quite a while.
    Fixed ROM names for kgbird/kgbirda; 5c and 10c variants were mixed up.

    11/12/2014 - Lord-Data
    Added hopper and meter outputs.

    27/03/2014
    Added new game: Guns and Roses Poker - gunnrose

    13/11/2015 - Roberto Fresca
    Added new game: Fever Pitch (2VXEC534, NSW, 90.36%).

    26/04/2017 - Heihachi_73
    Added button labels and layout to gunnrose, position of buttons is guesswork at this stage.
    This game does not have a cashout button. Credits are paid out using the jackpot key.
    Changed jackpot and audit keys to F1 and F2 respectively.
    Renamed nodump program ROM in clkwise as it had the wrong EPROM number.


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

    When the games first power on (or when reset), they will display a TILT message on the screen.
    This doesn't affect gameplay, and if there are no pending errors the game should coin up and/or play immediately.

    The tilt message will also appear when an error code is displayed, such as the main door being opened/closed, or
    a hardware error/fault (such as hopper empty, coin yoyo, printer errors; none of which should happen in MAME however).

    The tilt message will disappear if you turn the Audit Key on and off, or after you start playing.
    Despite the name, there is no 'tilt' mechanism in the machine and there is nothing to worry about.
    The first Aristocrat system to have a tilt mechanism was the MK5, which will cause the machine to reset abruptly
    if the player is too rough (e.g. hitting the screen or bumping the machine).

    These games do not feature a backup mechanism in case of power faults or system crashes requiring a reboot;
    if the player was in the middle of a spin or watching a win count up, any credits won on that spin will be voided.
    On the machine's artwork, this is reflected with text reading 'Malfunction voids all pays and plays', of which
    the text has also been carried onto later machines. The Aristocrat MK5 and later systems however feature backup
    mechanisms and will repeat the last game (including free game features and/or gamble selection) when powered on,
    to where the player had left off.

    Gone Troppo and Caribbean Gold 1 and 2 require DIP SW7 to be set to off/off or else the second screen will be broken.
    This is possibly true to the original machine.

    A similar thing happens with Top Gear, the drag cars' tyres will only be the correct colour (grey) if SW7 is off/off.

    In Wild One, the dollar sign on the Insert $2 graphic is the wrong colour on other settings as well. It only appears
    correct when SW7 is off/off. This is probably a bug in the original game, where the graphic designers have used the
    wrong palette for the background of the dollar sign.

    From these findings, it is noted that the off/off setting may in fact be the default background setting of all games.

    cgold, gtroppo and topgear are non-multiplier, 5 payline games, therefore, you cannot bet higher than 5 credits on these machines.

    cgold can be set to credit play or coin play by toggling SW1-5. If SW1-5 is on, game is in credit mode; if SW1-5 is off,
    wins and remaining credits will be automatically paid out as coins.

    Non-US games can enable/disable the double up (gamble) option by toggling the SW1-8 switch. Turning SW1-8 off will enable
    the double up option (default); turning SW1-8 on will disable double up and enable auto-spin on some games (so far, only
    eforesta and 3bagflvt allow this; other games simply ignore the buttons). The games respond slightly faster between games
    with double up disabled.

    3 Bags Full, Fortune Hunter, Fever Pitch, Caribbean Gold 1 and 2, Gone Troppo and Top Gear do not have a double up option,
    and US-based games ignore this switch setting (double up is always enabled on US games which support it).


    TODO:

    1. ROMs need redumping for the following games:
     - White Tiger has bad graphics ROMs.
     - Caribbean Gold 2 is missing two graphics chips.
     - Clockwise needs its program ROM redumped, original dump was 32K of 0xFF's. Graphics and video/sound ROM are OK.
     - PROM dumps needed for Top Gear (2CM33), Caribbean Gold (1CM12), Caribbean Gold 2 (unknown), Clockwise (2CM18),
        Golden Poker (unknown), and Fever Pitch (unknown).

    2. Video poker and Keno button panels needed. 06/06/11: Video poker panels done, however they need confirmation
       with a real machine.

    3. Extend the driver to use the keno keyboard input for keno games (no MK2.5/MKIV Keno games dumped yet as of 28/02/2010).

    4. Provide complete cashcade emulation

    5. Look into what the hopper probe signal is for.

    6. Investigate issues with the Poker style games as described below.

    7. When DIP SW7 is set to off/off, speed is dramatically reduced (noticeable on older Pentium 4-based systems).

    8. Rewrite video emulation by using custom drawing code.

    9. Check what type of mc6845 this HW uses on real PCB, and hook it up properly.

    10. Fix 86 Lions (pre-Aristocrat Mk-4 HW, without prom and dunno what else).

    11. Fix coin input for the US games. Currently, only the note acceptor works. The reverse is true for cgold.


    ***************** POKER GAMES ************************************************************************

    Wild One & Golden Poker have a problem where the second branch condition is always true, see assembler below for
    example of Wild One.

    907D    BITA $1800  ( crtc )
    9080    BNE  $907D  ; is zero
    9082    BITA $1800
    9085    BEQ  $9082  ; branches to 9082 indefinitely, value is always zero.
    9087    LDA  #$40

    If the PC ( program counter ) is set to 9087 then the game runs.

    Bug in the 6845 crtc core ? Seems like some kind of logic there not working.

    EDIT: it's a vblank check, BITA opcode checks bit 5 in A register and compares it with the contents of 0x1800
    (that is vblank in mc6845_status_r). Checking if a bit goes low then high it usually means that is moaning for
    a vblank. ;-)
    But now there is a new question: what kind of mc6845 clone this HW uses? It's clearly not standard mc6845,
    since that version doesn't support vblank reading. The vblank bit can be read only on C6545-1, R6545-1, SY6545-1
    and SY6845E subvariants, so it all lies to those. -AS
