Pooyan memory map (preliminary)

Thanks must go to Mike Cuddy for providing information on this one.

Sound processor memory map.
0x3000-0x33ff RAM.
AY-8910 #1 : reg 0x5000
	     wr  0x4000
             rd  0x4000

AY-8910 #2 : reg 0x7000
	     wr  0x6000
             rd  0x6000

Main processor memory map.
0000-7fff ROM
8000-83ff color RAM
8400-87ff video RAM
8800-8fff RAM
9000-97ff sprite RAM (only areas 0x9010 and 0x9410 are used).

memory mapped ports:

read:
0xA000	Dipswitch 2 adddbtll
        a = attract mode
        ddd = difficulty 0=easy, 7=hardest.
        b = bonus setting (easy/hard)
        t = table / upright
        ll = lives: 11=3, 10=4, 01=5, 00=255.

0xA0E0  llllrrrr
        l == left coin mech, r = right coinmech.

0xA080	IN0 Port
0xA0A0	IN1 Port
0xA0C0	IN2 Port

write:
0xA100	command for the audio CPU.
0xA180	NMI enable. (0xA180 == 1 = deliver NMI to CPU).

0xA181	interrupt trigger on audio CPU.

0xA183	maybe reset sound cpu?

0xA184	????

0xA187	Flip screen

interrupts:
standard NMI at 0x66
