The 32X relies on multiple edge connectors between itself and the Megadrive/Genesis, as well as patch cables for AV and power. Oxidation or dirt can cause poor contact and system instability. | The 32X relies on multiple edge connectors between itself and the Megadrive/Genesis, as well as patch cables for AV and power.
