Setting Up Your PC Game Controller
Plug your PC game controller into a USB connection on your PC.
Follow any on-screen instructions for configuring your PC controller or installing drivers.
Ensure that your PC game controller is working properly before loading any Nintendo games.
Playing Nintendo Games With Your PC Game Controller
Download a Nintendo emulator, such as FCEUX or Nestopia. An emulator acts like a Nintendo Entertainment System console on your PC. Most modern PCs can handle an emulator without difficulty, but if your PC is older, check the minimum requirements on the emulator page.
Download Nintendo ROMs to your PC. ROMs are files that contain all of the game data that is normally on a Nintendo cartridge. They are in digital form, so they can run on your PC using an emulator. You may only download ROMs for games that you own.
Create a games directory on your hard drive and unzip the compressed ROM files.
Open the emulator and click on "File," and then "Open." Choose the game you want to play from the list of ROMs, and double click the title. If the emulator does not detect your PC game controller, click on "Options" and then "Controller," and choose it from the list.
