Juno First :  memory map same as tutankham with some address changes
Chris Hardy (chrish@kcbbs.gen.nz)

Thanks to Rob Jarret for the original Tutankham memory map on which both the
Juno First emu and the mame driver is based on.

        Juno First memory map by Chris Hardy

Read/Write memory

$0000-$7FFF = Screen RAM (only written to)
$8000-$800f = Palette RAM. BBGGGRRR (D7->D0)
$8100-$8FFF = Work RAM

Write memory

$8030   - interrupt control register D0 = interrupts on or off
$8031   - unknown
$8032   - unknown
$8033   - unknown
$8034   - flip screen x
$8035   - flip screen y

$8040   - Sound CPU req/ack data
$8050   - Sound CPU command data
$8060   - Banked memory page select.
$8070/1 - Blitter source data word
$8072/3 - Blitter destination word. Write to $8073 triggers a blit

Read memory

$8010   - Dipswitch 2
$801c   - Watchdog
$8020   - Start/Credit IO
                D2 = Credit 1
                D3 = Start 1
                D4 = Start 2
$8024   - P1 IO
                D0 = left
                D1 = right
                D2 = up
                D3 = down
                D4 = fire 2
                D5 = fire 1

$8028   - P2 IO - same as P1 IO
$802c   - Dipswitch 1



$9000->$9FFF Banked Memory - see below
$A000->$BFFF "juno\\JFA_B9.BIN",
$C000->$DFFF "juno\\JFB_B10.BIN",
$E000->$FFFF "juno\\JFC_A10.BIN",

Banked memory - Paged into $9000->$9FFF..

NOTE - In Tutankhm this only contains graphics, in Juno First it also contains code. (which
        generally sets up the blitter)

    "juno\\JFC1_A4.BIN",    $0000->$1FFF
    "juno\\JFC2_A5.BIN",    $2000->$3FFF
    "juno\\JFC3_A6.BIN",    $4000->$5FFF
    "juno\\JFC4_A7.BIN",    $6000->$7FFF
    "juno\\JFC5_A8.BIN",    $8000->$9FFF
    "juno\\JFC6_A9.BIN",    $A000->$bFFF

Blitter source graphics

    "juno\\JFS3_C7.BIN",    $C000->$DFFF
    "juno\\JFS4_D7.BIN",    $E000->$FFFF
    "juno\\JFS5_E7.BIN",    $10000->$11FFF

/* Juno First Blitter Hardware emulation

    Juno First can blit a 16x16 graphics which comes from un-memory mapped graphics roms

    $8070->$8071 specifies the destination NIBBLE address
    $8072->$8073 specifies the source NIBBLE address

    Depending on bit 0 of the source address either the source pixels will be copied to
    the destination address, or a zero will be written.

    Only source pixels which aren't 0 are copied or cleared.

    This allows the game to quickly clear the sprites from the screen

    TODO: Does bit 1 of the source address mean something?
          We have to mask it off otherwise the "Juno First" logo on the title screen is wrong.
