The reader is an esp 32, with a cheap ($27) e-ink display + d pad (on the back) in 4 sheets of laser cut acrylic. The esp32 can broadcast wifi, so it serves an emulator to the browser and the rom, so processing is on device, but my save is persistent across devices. The e-ink ux is made from in game assets and sprites, and reads the memory position from the emulator to get all the game data.

Total cost of the project is around $40, I did a full write up of the e-ink build [here](https://muonsortes.com/build-a-wifi-ereader).  
  
I'm building out an open source hardware + software platform for games and stuff based around the eink + esp32 able to broadcast wifi to local devices without an app download or internet connection, I had this running on a $15 3.5" e-ink display for v1. Super fun project  
  
Another proof of concept I have is Texas Hold'em where the cards are on the e-ink then players have their hands on their phones/devices. If you're interested I'm mostly posting about that on my [insta](https://www.instagram.com/_stition/) if you want to know more. I'll be putting together the git repo on monday, if anyone is interested in working on this with me I really think there is a lot of potential for this as a mod-able platform.

Claude helped me make a custom e-book, and now I can play pokemon on any device with a web browser and use the display as a game dashboard!
