YouTuber Wenting Zhang has built a Game Boy emulator using a 4.7-inch E-Ink touchscreen and the ESP32 chip, demonstrating that E-Ink displays are capable of supporting high-performance retro gaming experiences. Unlike conventional E-Ink displays, the Paper Boy S3 features a refresh rate suitable for Game Boy Original titles. The creator has shown what can be achieved with basic hardware and some additional tinkering. This project serves as a testament to the potential of E-Ink displays in the realm of retro gaming.

Playing Game Boy on an E-Ink screen looks surprisingly good

The Paper Boy S3

The Paper Boy S3 is a development device used by developers to tinker and build experiences for E-Ink displays. It is built using the M5Stack PaperS3 and the ESP32 chipset, a popular choice for E-Ink-based projects. The PaperS3 is a development device used by developers to tinker and build experiences for E-Ink displays. Before bringing this project to life, Zhang spent four years developing the portable E-Ink display with a 60Hz refresh rate, which we know as the Modos Flow.

The Challenges and Solutions

The Paper Boy S3 is capable of running original Game Boy titles such as Pokémon Blue. However, support for Game Boy Color is not yet ready, and Zhang mentions some issues with Bluetooth connectivity. To improve the sound on the Paper Boy S3, Zhang had to get creative, resulting in a unique solution. The creator has uploaded the Paper Boy S3 firmware, enabling enthusiasts with access to the right hardware to take this unique Game Boy emulator for a spin themselves.

Conclusion

Even though the M5Stack PaperS3 has reached end-of-life status, the creator remains hopeful that a replacement or next-gen model will be available soon. This also explains why there isn’t a crowdfunded effort to get it to market, unlike the Modos Flow. The Paper Boy S3 is a testament to the potential of E-Ink displays in the realm of retro gaming, demonstrating that you can build practically anything if you put your mind to it.
