Game Boy emulator runs at 60 FPS on ESP32-S3 E Ink devkit using display optimization tricks

Summary
Wenting Zhang's PaperBoy project runs a Game Boy emulator at 60 FPS on an ESP32-S3-based M5Stack PaperS3 devkit with a 4.7-inch E Ink display. The project achieves smooth performance by using the bottom portion of the ePaper touchscreen for static control buttons (no refresh needed) and scaling the active 160x144 Game Boy resolution three times to render shades of grey. This demonstrates a clever optimization for gaming on typically slow-refresh E Ink displays.

· 3 pulled60 FPS gaming on an E Ink display? That doesn't seem right…
the bottom part of the ePaper touchscreen display is used for control buttons and doesn't need to be refreshed
the active part only requires 160 x 144 resolution, scaled three times to represent various shades of grey
