Well, i have a pirate cart with an "unknown" mapper and i'd like to dump it with my copynes but i don't know how to begin because my understandig of how a nes works is very, very basic, so any help would be very apreciated.
The cart is this one:
it's a game by microgenius/txc called policeman, and as you can see it's using two ls chips (138 and 175), a "custom chip" and two 27c512 eproms. If this pcb didn't have that custom chip, it would be very similar to that ¿ave? mapper made of those two ls chips... but it has it so i don't know how to begin... and what troubles me most is that i'wont be able to know wheter is a good dump or not until that mapper is emulated
¿can anybody help me?
