Is your console giving you problems Do your games seem to be not working the way they used to® Or maybe your screen just flashes yellow and gray® It could be that your old 72 pin connector is broken! The original connectors had a design flaw, and were made of cheap metal that corrodes after time. This connector is made of a much stronger metal than the original. It is the strongest one you can find and it will not corrode over time. It is compatible with the NES®. A Phillips head screwdriver is needed to complete installation in minutes.
