The NES CIC lockout chip prevents the system from running import games. Disabling this is a simple process of either breaking connections to the chip (destructive) or using wires to reroute signals (non-destructive). I offer this non-destructive wire method as a service. It’s a simple mod but one that offers obvious benefits.
Whilst I have your console open I will also give it a thorough clean and ensure the 72-Pin Cartridge connector is working reliably.
This listing will soon be offering full NES capacitor replacement, RGB video, IGR and IO board installs.
