I came across a post from Pixel Cherry Ninja on X of a new flashcart made by David Brito, who has turned this thought into a reality. David has a big history of modding retro consoles, having adapted N64s to be powered by USB-C, working with HDMI mods, and creating better controller solutions. He even made a built-in display for the Xbox 360 which is incredibly cool!



Has been for about 15 years, although decent ones didn’t come out until 10 years ago.
Huh, TIL. Crazy that I’ve never encountered them.
I think they’ve got a number of drawbacks, so that’s why. IIRC they have a low refresh rate, and they’re pretty pricy. For this application, where it’s a small screen and you only need the one, and you’ll only refresh it rarely, it makes sense though.
I’ve only ever seen one IRL, and it was insane how much like actual paper it looked.
That’s fucking cool. I’ll have to look more into it.
