But there’s usually a price to pay: the closer you get to 60 fps, the more ghosting and stuttering you’re likely to see.But developer Wenting Zhang came up with a DIY project that seems perfect for a small E Ink display. He ported an open source Game Boy Emulator to run on M5Stack’s M5PaperS3 device with an ESP32-S3 chip and a 4.7 inch, 960 x 540 pixel E Ink display. The result is PaperboyS3, a Game Boy emulator for the M5PapserS3 that look pretty good on video.Here’s the basic idea: it takes a while to perform a full screen refresh on an E Ink display, but if you just focus on the individual pixels that need to change, while leaving the rest unchanged, things can go much quicker.It also helps that the original Game Boy only had a 160 x 144 pixel grayscale display (or greenscale, really). Even scaled up two three times the original pixel density, the emulator window only takes up a portion of the M5PaperS3 display, while the bottom shows a static set of game controller buttons.As Wenting Zhang describes in a writeup, getting the display to function properly while using the CrankBoy emulator wasn’t the only challenge. The M5Stack also lacks a proper speaker, instead using only a simple, single-tone buzzer. By quickly switching between 4 different audio channels, you can basically get the buzzer to play some chiptune-style music. It doesn’t sound exactly like a Game Boy, but it’s close enough to get the idea.There’s also basic support for Bluetooth controllers for folks that want to use tactile buttons rather than a touchscreen display.Overall, it’s a pretty impressive project… with one big drawback: the M5PaperS3 has reached end of life status and is no longer available for purchase at its original $59 price. You can still find some new or used units on eBay or from other retailers, but it tends to sell for more than twice the original price.
