Gun Dealer memory map

driver by Nicola Salmoria

Yam! Yam!? runs on the same hardware but has a protection device which can
           access RAM at e000. Program writes to e000 and expects a value back
           at e001, then jumps to subroutines at e010 and e020. Also, the
           player and coin inputs appear magically at e004-e006.

0000-7fff ROM
8000-bfff ROM (banked)
c400-c7ff palette RAM
c800-cfff background video RAM
d000-dfff foreground (scrollable) video RAM.
e000-ffff work RAM

read:
c000      DSW0
c001      DSW1
c004      COIN (Gun Dealer only)
c005      IN1 (Gun Dealer only)
c006      IN0 (Gun Dealer only)

write:
c010-c011 foreground scroll x lo-hi (Yam Yam)
c012-c013 foreground scroll y lo-hi (Yam Yam)
c014      flip screen
c015      Yam Yam only, maybe reset protection device
c016      ROM bank selector
c020-c021 foreground scroll x hi-lo (Gun Dealer)
c022-c023 foreground scroll y hi-lo (Gun Dealer)

I/O:
read:
01        YM2203 read

write:
00        YM2203 control
01        YM2203 write

Interrupts:
Runs in interrupt mode 0, the interrupt vectors are 0xcf (RST 08h) and
0xd7 (RST 10h)
