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)
