CONNECTING THE DOTS: The aesthetic similarities between E-ink screens and the original Game Boy aren't hard to spot, but no one had built a dedicated emulator for the paper-like display technology until now. Despite the Game Boy's age, porting its software to M5Stack's PaperS3 turned out to be surprisingly difficult.
M5Stack's PaperS3 was originally built for smart home controls, electronic labels, and educational tools. But YouTuber Wenting Channel recently detailed how he turned the old dev board into a 60Hz E-ink Game Boy, its paper-like display an unexpectedly good match for the handheld's graphical capabilities.
Wenting Channel used the PaperS3 display's unique configuration to hit the Game Boy's original 60Hz refresh rate, something he'd previously pulled off on other E-ink hardware. The gap between the PaperS3's 960x540-pixel resolution and the Game Boy's modest 160x144-pixel resolution actually worked in his favor.
The extra resolution also left room to emulate a control pad and buttons on the touchscreen. Wenting Channel even added quicksave and quickload buttons above the game window. Bluetooth controller support is included too, though its responsiveness and accuracy still need work.
