Doom conquers the kitchen via an electrical cooking pot — traditional shooter runs seamlessly after a full gadget firmware refresh

A YouTuber has managed to run Doom on a Krups Cook4Mec sensible stress cooker after dumping and reflashing the firmware on the equipment’s touchscreen management {hardware}. Documented in a teardown and reverse-engineering video, the YouTuber reveals the sport operating regionally on the cooker’s show with out modifying the electronics answerable for heating or security programs.

The start line was the built-in Wi-Fi of the Cook4Me. While looking the settings menu, the creator seen that “the first three bytes are from Espressif… so there’s most likely an ESP inside.” That statement prompted a full teardown of the equipment.

Opening the unit reveals break up {hardware}. At the underside of the gadget is what the creator describes as “really just a temperature sensor, a heating element with a safety switch.” This decrease board is constructed round an STM microcontroller and handles the heating relay, temperature measurement, and a fail-safe cutoff “in case something or the relay got stuck.”

Connected to it by a easy four-wire cable is the entrance touchscreen module. Removing that meeting exposes considerably extra succesful {hardware}. The Wi-Fi module is confirmed to be an ESP32, whereas the primary processor on the show board is recognized as a Renesas R7S721031VZ. The creator calls it “quite a nice chip,” including that “it is quite powerful and it has a lot of GPIOs. It’s an Arm core.”

The touchscreen board additionally contains 128MB of flash, 128MB of RAM, a capacitive contact controller, a show driver, a beeper, an exterior EEPROM, and “a non-populated SD card slot.” The ESP32’s flash was dumped and located to be encrypted. Logging urged cloud connectivity, with the creator noting that it hints “it being connected via AWS cloud so MQTT via a private key,” if he needed to do something with it.”

Access to the primary Renesas processor got here by way of SWD. After hooking up an SWD flasher to the proper pins, the creator efficiently dumped the flash. Bootloader logs made it potential to reverse-engineer how the LCD was initialized, enabling customized firmware to be constructed and flashed onto the chip.

With a working firmware atmosphere in place, Doom was ported to the touchscreen system. “After writing enough wrapper around Doom and porting it to the firmware, we can fully make it run on the cooking pot,” the creator explains. The sport runs on the Cook4Me’s show, with the touchscreen mapped to completely different areas for buttons, delivering what he describes as “a quite nice frame rate.”

Absurd, sure, however the video offers us an fascinating view into how sensible home equipment are constructed. The Cook4Me’s cooking logic stays remoted on a easy controller, whereas its interface and networking are dealt with by a much more succesful embedded laptop. In this case, that separation made it potential to run Doom on a stress cooker, and little question the Internet will convey us even more outlandish examples of weird devices to play Doom on in the near future.

There again, we’ve already had Doom in space, so perhaps that’s as weird as things are going to get.
