The world of retro gaming continues to thrive, and a recent project demonstrates just how accessible it is to tinkerers, and enthusiasts. A developer, derdacavga, has created a fully functional Nintendo Entertainment System (NES) emulator powered by the ESP32-S3 microcontroller, offering a surprisingly capable handheld gaming experience. This project isn’t about slick commercial products. it’s about the joy of building something yourself and breathing new life into classic 8-bit titles.
The appeal of the ESP32-based NES emulator lies in its affordability and DIY nature. Whereas modern gaming consoles boast impressive graphics and processing power, this project proves that compelling gaming experiences don’t always require cutting-edge technology. The ESP32-S3, a popular choice for embedded systems, provides enough processing muscle to run NES games smoothly, opening up a world of possibilities for hobbyists and makers. The project leverages the ESP32-S3’s dual-core power to deliver full-speed emulation, according to the GitHub repository.
At the heart of this build is the ESP32-S3 development board, paired with several readily available components. The emulator utilizes an ST7789 SPI TFT display for vibrant visuals, a MAX98357A I2S amplifier for high-quality audio, and a Micro SD card reader to store a library of ROMs – potentially hundreds of classic NES games. Control is handled through eight tactile push buttons, providing a full D-Pad and A/B plus Start/Select functionality. The project’s creator has even provided a detailed wiring diagram and pinout information, making the build process more accessible.
The project’s creator has also provided a helpful video tutorial on YouTube, demonstrating the build process step-by-step. Watch the build tutorial here. This visual guide complements the detailed instructions available on the GitHub page, making it easier for beginners to follow along. The GitHub repository, hosted by derdacavga, contains all the necessary files, including the emulator code, parts list, and wiring instructions. Identify the project on GitHub here.
Hardware Requirements
Building this emulator requires a few key components. According to the GitHub documentation, you’ll need:
- Microcontroller: ESP32-S3 (DevKit or bare module)
- Display: ST7789 SPI TFT Module (e.g., 1.69″)
- Audio: MAX98357A I2S Amplifier Module + 3W 4Ω Speaker
- Storage: Micro SD Card Reader Module + Micro SD Card (formatted FAT32)
- Controls: 8x Tactile Push Buttons (6x6mm)
- Power: LiPo Battery & Charging Circuit (Optional/TP4056)
- Wires & Perfboard: For connections
The project’s success hinges on the ESP32-S3’s capabilities. XDA Developers notes that the ESP32-S3’s dual-core power allows for full-speed emulation, delivering a smooth gaming experience.

This isn’t the first attempt at creating a portable NES emulator using microcontrollers. Hackster.io highlights a similar project utilizing an ESP32-S3, ST7789 TFT LCD, MAX98357A audio amplifier, and SD card reader, all wired on a breadboard. See the breadboard NES on Hackster.io. This demonstrates a growing trend of DIY retro gaming projects leveraging the power and affordability of modern microcontrollers.
The ESP32-based NES emulator represents a compelling intersection of retro gaming, DIY electronics, and the maker movement. It’s a testament to the ingenuity of hobbyists and the versatility of the ESP32 platform. As the project continues to evolve, we can expect to see further refinements and optimizations, potentially leading to even more sophisticated portable gaming solutions. The open-source nature of the project encourages community contributions, ensuring its continued development and accessibility for years to come.
If you’re interested in diving into the world of embedded systems and retro gaming, this project offers an excellent starting point. The readily available components, detailed instructions, and supportive community make it an achievable goal for makers of all skill levels. The future of DIY gaming looks bright, and projects like this demonstrate the enduring appeal of classic games and the power of open-source hardware.
