An eInk, ESP32-based Game Boy

Wenting Zhang built an e-ink Game Boy using the M5Stack PaperS3 board which combines an ESP32-S3 chip with a display panel. The project exposes row and column controls to enable partial refresh at up to 60 Hz while emulating Crank Boy software on screen. Touch inputs scale images three times larger than original hardware outputting black and white pixels only. Users flip orientation when high-refresh areas wear out doubling system lifetime despite one-bit buzzer sounds lacking Nintendo quality.
