Nintendo Entertainment System (NES) Setup Guide

Setting Up Your NES

To set up your Nintendo Entertainment System (NES), you’ll need the original power cable and either AV cables or an RF adapter. For use with modern TVs, AV cables are recommended.

Note: The NES supports only mono audio, so it uses just 2 of the standard 3 AV plugs (video + left audio). You may also need an AV-to-HDMI converter if your television lacks AV inputs.

For the most authentic experience, consider using a CRT television. These TVs eliminate input lag and better replicate how the graphics were originally intended to appear.

Playing NES Games

NES game cartridges (sold separately) must be inserted into the front-loading cartridge slot. There are two loading methods:

  • Locked-down position (standard): Insert and press the cartridge down until it clicks into place.
  • Upright position (alternate): Some systems read better without pressing the cartridge down, especially if the cartridge connector pins have been replaced.

We recommend trying both loading methods if the game doesn't start immediately.

Flashing Power Light

If the red power light flashes on and off instead of staying solid, the cartridge isn’t being read correctly. This usually indicates dirty or oxidized contacts.

Cleaning NES Cartridges

While blowing into cartridges was a common fix back in the day, it’s not recommended. Moisture from your breath can corrode contacts over time. Instead:

  • Use a cotton swab lightly dipped in rubbing alcohol.
  • Apply firm pressure when scrubbing the cartridge contacts—NES contacts are durable.
