Prominent hardware modder Wenting Zhang has successfully converted an M5Stack PaperS3 dev kit (which inludes an e-ink display and ESP32-S3 dual-core microcontroller) into a working Game Boy with the help of a modified CrankBoy emulator.

The result runs monochromatic Game Boy games at up to 60 Hz on an e-ink display, and the result is truly remarkable to see in action. Games including Pokemon Blue, Super Mario Land, and The Legend of Zelda: Link's Awakening all run well on the so-called "PaperBoy S3," though it's not completely perfect.

This results in audio instead being represented with shrill beeps, but the approximation is close enough that the original music is still recognizable, if inadvertently remixed by the hardware.

Additionally, frame-skipping is employed by the underlying CrankBoy emulator to...
