Gun Dealer memory map
driver by Nicola Salmoria
The custom graphics chips at locations labeled GA 1, GA 2 and GA 3 (x2) are
surface-scratched on common blue boards. However, a Tecmo-licensed green
PCB reveals them to be none other than NMK-901, NMK-902 and NMK-903.
Yam! Yam!? runs on similar 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.
Despite not using GFX customs or MCU protection and lacking Dooyong labels,
gundealrbl might be a factory conversion of Yam! Yam!? rather than a
bootleg, as its board has the same NMK-style markings for the ROM and PROM
locations. In place of the MCU here is a small daughterboard with three
SN74LS245N buffers, a resistor array and an Altera EP320PC.
0000-7fff ROM

c400-c7ff palette RAM
c800-cfff background video RAM
