3. Setting Up a Game Controller


RetroPie supports most USB and Bluetooth game controllers. Here’s how to set up your controller:

  • Connect your controller to the Raspberry Pi via USB or Bluetooth.
  • When prompted, hold down any button on the controller to start configuration.
  • Follow the on-screen instructions to map each button.
  • Save the configuration when complete.




4. Adding ROMs


To play games, you’ll need to add ROM files to RetroPie:

  • Step 1: Connect to your Raspberry Pi via a network or USB drive. (I connected remotely via samba)
  • Step 2: Navigate to the /home/pi/RetroPie/roms directory.
  • Step 3: Place your ROM files into the appropriate system folder (e.g., `nes` for NES games, psx for PlayStation).
  • Step 4: Restart RetroPie for the ROMs to appear in the menu.


Make sure you own the rights to any ROMs you use, as downloading copyrighted games without permission may violate copyright laws.





5. Basic Troubleshooting


If you encounter issues, here are some common fixes:

  • Controller Not Working: Reconfigure the controller via the RetroPie menu, I had to setup my keyboard first to enable me to connect my PS5 controller via bluetooth.
  • ROMs Not Showing: Ensure they are placed in the correct system folder and restart RetroPie.
  • Performance Issues: Overclock your Raspberry Pi or reduce video settings for smoother gameplay.




Conclusion


With RetroPie, your Raspberry Pi can become the ultimate retro gaming console. By following these steps, you’ll be ready to enjoy hours of classic gaming. Experiment with settings, add your favourite ROMs, and relive the nostalgia!
