Doom conquers the kitchen through an electric cooking pot — classic shooter runs seamlessly after a full device firmware refresh

A YouTuber successfully ran Doom on a Krups Cook4Mec smart pressure cooker by reprogramming the appliance's touchscreen hardware. The device's built-in Wi-Fi led to a full teardown, revealing an ESP32 Wi-Fi module and a Renesas R7S721031VZ main processor on the display board. By reverse-engineering the LCD initialization process and flashing custom firmware, Doom was ported to the touchscreen system, allowing the game to run on the cooker's display with touchscreen controls. This unconventional use of a kitchen appliance showcases the capabilities of smart devices and the potential for running unexpected software on them.
