Is your NES 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 72pin 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 works with the original 8-bit Nintendo system, and is simple to replace, only a Phillips head screwdriver is needed to complete installation in minutes.
