Another day, another person getting Doom running on something it was never intended to - this time, Notepad!
If I had a nickel for every weird place you're able to play Doom, I'd probably have quite a few nickels, because people just seem incredibly determined to get it to run on anything they can get their hands on. Today, this particular nickel of mine comes from developer Samperson, who got Doom running on the note taking software Notepad (slight flashing warning in the example video seen below).
While it's definitely one of the more unreadable versions of Doom, you have to admit when watching the video, this is in fact Doom. The game itself is obviously made up of a bunch of various characters lined up to resemble the visuals of Doom. It even sounds like Samperson got the audio and soundtrack working and synced up, which could not be anything but witchcraft.
