Transforming a tiny Raspberry Pi into a universal gaming console is one of the most rewarding DIY projects you can undertake. This guide will walk you through everything from buying the right parts to playing your first game.
1. Raspberry Pi Imager
IMAGER
The essential utility for flashing your SD card. It allows you to select your Raspberry Pi model and your preferred gaming OS in just a few clicks.
The ultimate retrogaming OS. It turns your Pi into a dedicated game console with a beautiful interface, automatic controller mapping, and advanced features like RetroAchievements.
The following components are strictly required to build and operate your retro gaming console.
Raspberry Pi Board
A Raspberry Pi 3, 4, or 5 is required. For 3D systems (N64, Dreamcast, PSP), a Raspberry Pi 4 with at least 2GB of RAM is the minimum requirement.
MicroSD Card
A Class 10 or UHS-1 MicroSD card is required. Minimum size of 16GB for the OS, though 64GB+ is recommended for storing game libraries.
Power Supply
A power adapter capable of providing 5.1V and at least 3.0A (for Pi 4) or 5.0A (for Pi 5) via USB-C or Micro-USB depending on your board model.
Display Cable
An HDMI cable compatible with your board (Standard HDMI for Pi 3, Micro-HDMI for Pi 4/5) and a display supporting at least 720p resolution.
USB Controller
At least one USB or Bluetooth game controller is required to navigate the menu and play games.
Passive Cooling
Heatsinks are required for the SoC to prevent thermal throttling during extended gaming sessions on Pi 4 and Pi 5 models.

Frequently Asked Questions
Can I play PS2 or GameCube games?
Generally, no. The Raspberry Pi 4 and 5 struggle with these systems. Some very lightweight PS2 titles might run on a Pi 5 with heavy overclocking, but it is not a smooth experience.
Do I need an internet connection?
Internet is required for the initial setup, scraping box art, and updating the software. However, once your games are loaded, you can play completely offline.
Which OS is better: RetroPie or Batocera?
RetroPie is great for users who like to tinker and customize. Batocera is better for users who want a "plug-and-play" console experience that looks beautiful out of the box.
Will my modern Xbox or PlayStation controller work?
Yes! Most modern Bluetooth controllers (Xbox One S/Series, PS4/PS5) work perfectly. You just need to pair them in the system settings.
Troubleshooting
Lightning Bolt Icon on Screen
This indicates under-voltage. Your power supply is not providing enough current. Ensure you are using a high-quality 5.1V 3A+ adapter and not just a standard phone charger.
Thermometer Icon / Slow Performance
Your Pi is overheating and "throttling" its speed to cool down. Check that your heatsinks are applied correctly and that your case has adequate ventilation or a fan.
No Signal on TV
For Pi 4/5, make sure you are using the Micro-HDMI port closest to the USB-C power input (Port 0). Also, try turning on the TV before powering on the Pi.
