Z80:
0000-7fff ROM
8000-bfff Banked ROM (4 banks)
c000-cfff RAM
d000-d7ff bg #1 video/color RAM (alternating pages 0x100 long)

e000-e3ff fg video RAM
e400-e7ff fg color RAM
e800-e97f sprites RAM

memory mapped ports:
read:
f010      IN0
f011      IN1
f012      IN2
f013      DSW0
f014      DSW1
f015      from pin 10 of 8751 controller
f016      from port #1 of 8751 controller

write:
f000      IRQ acknowledge
f001      sound command (also causes NMI on sound CPU)
f002      ROM bank selection
f003      flip screen
f004      NMI disable
f005      to port #2 of 8751 controller (signal on P3.2)

f00a-f00b bg #1 y scroll
f00c-f00d bg #2 x scroll
f00e-f00f bg #2 y scroll

interrupts:
VBlank triggers NMI.
the 8751 triggers IRQ

0000-07ff RAM
4000-7fff Banked ROM (2 banks)
8000-ffff ROM

read:
3400      command from the main cpu

write:
1000-1001 YM3526
2000      ADPCM data for the MSM5205 chip
2400      bit 0 = to sound chip MSM5205 (1 = play sample); bit 1 = IRQ enable
