GameBoy Runs on E-Paper ESP32 at 30FPS
GameBoy on E-Paper ESP32 at 30FPS [video]
A video demonstration shows a GameBoy emulator running on an ESP32 microcontroller with an e-paper display, hitting 30 frames per second. The project, shared on Hacker News, highlights how e-paper's slow refresh can still handle retro gaming with clever engineering.

This is insane. Almost everything done here to make things fast were things that I had assummed that e-ink displays aready did, because they are so slow, I figured their behaviour was the best that could be achieved after trying all these kind of tricks.
It makes me what other things could be much better if they received some attention from someone who cares about it.

I've been reading on an X3 (small eink display driven by esp32), and although I don't need better display performance, it would be cool! I wonder how long until these sort of driver improvements for e-ink filter down to other devices.
Great stuff.

Great work. I loved the technical innovations.
For the grayscale, I'm guessing each physical display would need to be individually calibrated? I also wonder whether the calibration is sensitive to environmental factors, i.e. gets out of whack if the display is too hot or too cold.

I don’t know if this particular display is magnetic particles or not, but epaper is not synonymous with eink. Something can be called epaper and still be lcd based. So I feel the video is misleading by declaring epaper is particle based.

I know e-ink has a whole lot of limitations, which is what makes this video impressive, but, what were the limitations on the hardware used in the original gameboy screens that prevented them from remaining popular? Wikipedia says that they were STN LCD.
