WHAT NEXT? If something runs on an electronic chip, someone will inevitably try to run Doom on it. The latest addition to the growing list of devices, appliances, and other objects that can play id Software's 1993 classic is a $50 HDMI adapter Apple released over a decade ago. The process required deep analysis of the dongle's surprisingly complex internals. Tinkerer John "Nyan Satan" recently demonstrated Doom running on Apple's Lightning Digital AV adapter. Although the gameplay looks choppy, the fact that the dongle released over a decade ago can handle the game at all is impressive. In some ways, it compares surprisingly well to the PCs that ran id Software's iconic first-person shooter in 1993.The minute-long clip shows a MacBook feeding data and inputs to the $49 adapter, which runs the game and connects to a monitor atop a tangle of wires. While the frame rate isn't nearly as high as on a modern PC, other devices have fared worse in Doom's three-decade history of unconventional ports.In a lengthy 2019 Twitter thread, John explained that Apple's HDMI dongles contain an SoC labeled S5L8747. Little is known about it except that it receives a 25MB firmware bundle from any iPhone it's connected to and features 256MB of RAM 32 times the 8MB listed in Doom's original system requirements.Modding Apple Digital AV adapters to connect to PCs or Macs is relatively simple, as they are fundamentally HDMI devices. Predictably, one of the first responses to John's analysis was the inevitable question: Can it run Doom? Six years later, he demonstrated that, yes, it can. // Related StoriesAccording to Tom's Hardware, John plans to further optimize performance to 60fps, add audio support, integrate controller compatibility (removing the need for a Mac), and eventually release the mod publicly. Installing it, however, requires a jailbroken iOS device.Thanks to Doom's legendary status and its practically nonexistent system requirements (by modern standards), it has become a favorite benchmark for running software on low-power devices. The ever-growing list of things that can run Doom now includes:
