    Mikie memory map (preliminary)
    GX469

    driver by Allard van der Bas


    MAIN BOARD:
    2800-288f Sprite RAM (288f, not 287f - quite unusual)
    3800-3bff Color RAM
    3c00-3fff Video RAM
    4000-5fff ROM (?)
    5ff0      Watchdog (?)
    6000-ffff ROM


Stephh's notes (based on the games M6809 code and some tests) :

  - To enter service mode, keep START1 and START2 pressed on reset.
    Then press START1 to cycle through the different tests.
  - According to code at 0x618f, you can start a game with 255 lives
    if you set DSW1 and DSW2 to the following settings :
      * "Coin A"      : "Free Play"
      * "Coin B"      : "No Coin B"
      * "Lives"       : "7"
      * "Cabinet"     : "Upright"
      * "Bonus Life"  : "20k 70k 50k+"
      * "Difficulty"  : "Medium"
      * "Demo Sounds" : "Off"
    DSW3 is not tested here, so settings can be anything.
  - I'm very surprised to notice that 'mikie' and 'mikiej' have the same
    PRG ROMS but different GFX ROMS.
    This is very rare (unique ?) for the Konami games.
  - There might exist undumped Konami/Centuri version(s) of this game :
    the manual I've found speaks about a "conversion kit".

  Convert the color PROMs into a more useable format.

  Mikie has three 256x4 palette PROMs (one per gun) and two 256x4 lookup
  table PROMs (one for characters, one for sprites).
  I don't know for sure how the palette PROMs are connected to the RGB
  output, but it's probably the usual:

  bit 3 -- 220 ohm resistor  -- RED/GREEN/BLUE
        -- 470 ohm resistor  -- RED/GREEN/BLUE
        -- 1  kohm resistor  -- RED/GREEN/BLUE
  bit 0 -- 2.2kohm resistor  -- RED/GREEN/BLUE
