An enthusiast published a video showing the classic Doom running on the Nintendo Alarmo smart alarm clock. The clip clearly shows the gameplay on the clock’s screen, illustrating a surprising crossover between a timekeeping device and a legendary shooter.
The creator first demonstrated that the device could run custom code. He managed to place a cat image on the screen as a basic test, a small victory that proved the hardware could render more than just a clock face. After that initial success, he pushed further and ported the cult shooter Doom from id Software to Alarmo.
The Alarmo device was introduced in October, and the official page lists a price of one hundred dollars. The device is described as a compact smart alarm clock with enough processing power to handle simple games and themes beyond timekeeping.
Nintendo has promised ongoing updates for Alarmo that add watch faces inspired by popular games. Fans can now enjoy themes in the style of Super Mario Odyssey, The Legend of the Zelda Breath of the Wild, Pikmin 4, Splatoon 3 and Ring Fit Adventure. These themes transform the clock face and perhaps the user interface to evoke beloved game worlds, making mornings and late nights a bit more playful.
Regarding Doom, the game has a history of appearing on unconventional displays. Earlier experiments included a 3D holographic projection that showcased the game’s fast action. The Alarmo port represents another step in the ongoing curiosity of fans who push hardware beyond its original scope, testing limits and imagining new possibilities for small screens.
These demonstrations reflect a broader trend where hobbyists tinker with consumer devices, showing the versatility of modern hardware and the creativity in open ecosystems. While unofficial and unsupported by manufacturers, such experiments capture the imagination of a community eager to repurpose tech for entertainment and novelty.
As with many homebrew projects, the soundness and stability of such ports depend on ongoing community experimentation, potential firmware limitations, and the willingness of developers to publish tools that simplify the process. The Doom port on Alarmo is a proof of concept that showcases what can be possible when curiosity meets technical skill and a friendly community of enthusiasts pushes the boundaries of everyday devices.
