RW93085 (C) NTC CO. on main PCB

|
|
RW93085-SUB (c)NTC CO.LTD 1993 MADE IN JAPAN on sub (ROM) PCB
|
|
|
|
various NMK customs including NMK005 near dipswitches, difficult to read the rest from PCB pics
|
|
possible MCU or just IO extender?
|
|
|
|
developed by NTC on NMK hardware?
|
|
|
|
video is probably just 2 tilemap layers
|
|
maybe close to jalmah.cpp?
