  Playmark 'Super Derby' Hardware
  -------------------------------

  Driver by David Haywood.
  Additional work by Roberto Fresca.


  Supported games:

  Super Derby,                  1996, Playmark.
  Scacco Matto / Space Win,     1996, Playmark.
  Croupier (Playmark Roulette), 1997, Playmark.


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

  NOTES:
  -----

  Payout / hopper controls not connected

  Roulette appears to have some kind of MCU device
  between the processor and the hopper


  Working notes: (Relating to SDERBY)

  Stephh's notes :

  - The game is playable, but :

      * it isn't possible to decrease the bet (but it might be an ingame "feature")
      * it isn't possible to insert a note
      * it isn't possible to exchange the winning points against tickets or cash

  - The settings can be modified in the "test mode", but there aren't mapped to
    input ports.


  EC notes :

  Thinks... Those three reads at the beginning - hopper, ticket and note acceptor tests?
  The system certainly performs those before printing the error.
  (There are three different error graphics in the ROM, depending on what is wrong)
  Also, hardware freezes if we try to turn the dispenser or acceptor on, because it's waiting
  for the response back from NOP?


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

  TO DO :

  - figure out the reads from 0x308002.w and 0x30800e.w (see sderby_input_r read handler)
  (by default, demo sounds are OFF, so change this in the "test mode")

    Roulette MCU communication.
    ---------------------------

    Defeating the 'always win' protection...

    Offset: 0x70800e - 0x70800f.

    Writes to the MCU are always the same values.
    At begining, the code writes 3 values: 0x53, 0x5a and 0x0d.
    Then, whith each placed bet the code normally writes 0x4e.
    After that, there are 2 reads expecting the MCU response.

    Most probably there is a shared RAM there for communication,
    but for now, I temporarily simulated the MCU response till
    we can get the MCU decapped.
