Hardware creator Alejandro Villegas Alonso built a playable port of the original Tomb Raider that runs on the ESP32-P4 microcontroller, featuring a RISC-V SoC with two 400 MHz cores and a datasheet-stated power draw of about 1 W. The port uses the open-source OpenLara engine and implements software rendering, audio, and USB HID keyboard input.
The project runs on the ESP32-P4-Function-EV-Board, which includes a 1024 x 600 seven-inch capacitive touchscreen and a camera module and therefore raises the board's total power budget above the chip's 1 W. Alonso's build renders at 320 x 240 in RGB565 then hardware-scales to 1024 x 600 via the Pixel Processing Accelerator, outputs stereo sound through an ES8311 codec, and accepts USB keyboard input.
Cheap development boards costing under $30 make this approach accessible to retro-gaming tinkerers and DIYers who want lower-power alternatives to full PCs. The setup shows how modest microcontrollers can revive classic titles with tight software rendering and small hardware footprints, and it may inspire more energy-efficient handheld or embedded ports.
