Green Beret memory map (preliminary)

gberetb is a bootleg hacked to run on different hardware.

driver by Nicola Salmoria


0000-bfff ROM
c000-c7ff Color RAM
c800-cfff Video RAM
d000-d0c0 Sprites (bank 0)
d100-d1c0 Sprites (bank 1)
d200-dfff RAM
e000-e01f ZRAM1 line scroll registers
e020-e03f ZRAM2 bit 8 of line scroll registers

read:
f200      DSW1
          bit 0-1 lives
          bit 2   cocktail/upright cabinet (0 = upright)
          bit 3-4 bonus
          bit 5-6 difficulty
          bit 7   demo sounds
f400      DSW2
          bit 0 = screen flip
          bit 1 = single/dual upright controls
f600      DSW0
          bit 0-1-2-3 coins per play Coin1
          bit 4-5-6-7 coins per play Coin2
f601      IN1 player 2 controls
f602      IN0 player 1 controls
f603      IN2
          bit 0-1-2 coin  bit 3 1 player start  bit 4 2 players start

write:
e040      ?
e041      ?
e042      ?
e043      bit 3 = sprite RAM bank select; other bits = ?
e044      bit 0 = nmi enable, bit 3 = flip screen, other bits = ?
f000      ?
f200      SN76496 command
f400      SN76496 trigger (write command to f200, then write to this location
          to cause the chip to read it)
f600      watchdog reset (?)

interrupts:
The game uses both IRQ (mode 1) and NMI.


TODO:
gberetb:
- cocktail mode
mrgoemon:
- flickering rogue sprites
- it resets during the first boot sequence, but works afterwards
