This was posted by Maserati52 on Reddit. As it turns out, getting Doom running on the hardware isn’t difficult. GoPro’s controllers use Android software, and all you need to do is install a new version of Android, and the Android port of doom should boot up without any issue. Moving around and shooting is a different story. The controls are strangely mapped beyond the left joystick, none of the other buttons activate weapons, and Maserati52 doesn’t believe remapping is a possibility.
Later in the thread, they point out that doing this absolutely did some damage to the controller. Funnily enough, GoPro isn’t keen on you tinkering with the operating system willy-nilly, and then using it to play old games for internet points. Maserati52 had to factory reset a few times to get things back to normal. We’re not saying enhanced Doom functionality would shift more drones, but at the very least, the PCGN team would probably be more interested if that became a thing.
