Recently, Bob from TheKeebProject was able to run the iconic Doom game directly with a keyboard key! The Raspberry Pi RP2040 microprocessor became the basis for this.
The project is based on a miniature circuit board with the RP2040 microprocessor enclosed in a transparent resin-filled switch.
This Doom port is a modification of an existing RP2040 port created by Graham Sanderson. Bob adapted it to support SPI and I2C display modules.
The aim of the project was to recreate Doom with as many original features as possible, including stereo sound, multiplayer, save/load functionality and the original 320 x 200 pixel resolution.
Playing Doom with a keyboard key doesn’t sound like much, but it’s a technical feat that definitely deserves attention.
Bob has made his project public and anyone interested can check out the source code on GitHub.
