    memory map (preliminary)

    Main processor memory map.
    0000-5fff ROM
    a000-a3ff Color RAM
    a400-a7ff Video RAM
    a800-afff RAM
    b000-b7ff sprite RAM (only areas 0xb010 and 0xb410 are used).

    memory mapped ports:

    read:
    c000      video scan line. This is used by the program to multiplex the cloud
              sprites, drawing them twice offset by 128 pixels.
    c200      DSW2
    c300      IN0
    c320      IN1
    c340      IN2
    c360      DSW1

    write:
    c000      command for the audio CPU
    c200      watchdog reset
    c300      interrupt enable
    c302      flip screen
    c304      trigger interrupt on audio CPU
    c308      video enable (?). Protection ??? Stuffs in some values computed
              from ROM content
    c30a      coin counter 1
    c30c      coin counter 2

    interrupts:
    standard NMI at 0x66

    SOUND BOARD:
    same as Pooyan
