Now you can play Doom over teletext

Add another one to the list of weird and delightful ways to play ye olde Doom: teletext. A new mod converts Doom to a teletext signal, letting you play the seminal shooter rendered in blocky teletext art on a telly. You can even control it with your TV remote. Have a look in the video below! I really, really like the smiley face replacing Doomguy's gurn.

You can download the teletext-doom mod from GitHub. Right now, it only supports the original Doom. Obviously it takes a bit of work to get running even on computers, though you really can set it up to play on a real television if you want—and if your TV can handle it. The developer, Lukneu warns that "many modern TVs seem to struggle when updating teletext pages", with their modern LG groaning along at 3fps while an old CRT happily plays at 30fps.

You might remember teletext art being prettier than this but Lukneu says it's an intentional decision. While later revisions of teletext tech added support for more colours, higher-resolution graphics, and other handy bits, this uses the original Level 1 teletext standard "mainly because it just feels like 'real' teletext to me and I like the original blocky look."

Teletext, I'll explain for the benefit of folks who never had it, was a bit like a magazine inside your television. The tech hid data streams inside unseen portions of the TV transmission, accessed by opening teletext and entering page numbers, and had just enough space for text and low-resolution ASCII art. You could get news, sports, TV listings, quizzes, dating profiles, and so much more. It was ultimately made obsolete by the Internet but for a while was very exciting and handy.
