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

TL;DR YouTuber Wenting Zhang has built a Game Boy emulator using nothing but a 4.7-inch E-Ink touchscreen and the ESP32 chip. Unlike conventional E-Ink displays, the Paper Boy S3 features a refresh rate suitable for Game Boy Original titles. The Paper Boy S3 has some limitations right now, though the creator has shown what can be achieved with basic hardware and some additional tinkering.
