Show-and-Tell I built a custom RPI Pico based controller/display for DOOM running on old WiFi router

Enable HLS to view with audio, or disable this notification

Hey everybody. I ported original 1993 DOOM to my old Mi Redmi AC2100 router. The hardest thing was to figure out the controls and display output for this thing because I didn't really want to use compuer for any of that. So i built a small controller out of RPI Pico, ST7789V display and W5500 Ethernet module. Image is sent via UDP unfragmented packets 4 lines at a time. So every frame is 80 packets. Input is also sent through UDP, but packets are much smaller. I have a repo if anybody wants to try this at home: https://github.com/anhol0/redmidoom

I hope you enjoy it. And have a good day :)

Well done and thank you for sharing!

One of my favorite genres of any weird computer science experiment frankenbuild are the ones that ends with "and ran Doom on it".
