Introduction
The 72-PIN connector is a piece of hardware inside of the game console. It has 72 metal pins, which come into contact with the metal spokes inside of the game cartridge to register the game. The pins on the connector bend out of place over time, and the game console can no longer register your games. This guide will show you how to locate and remove your worn out 72-PIN connector.
