SUMMARY
The Canon EOS 550D, a DSLR released in 2010, has been successfully modified to run the 1993 video game Doom. This feat was achieved using Magic Lantern, unofficial custom firmware for Canon cameras. The hack allows users to navigate the game with the camera's D-pad and fire with the SET button, while the camera's built-in speaker produces in-game audio. It's important to note that installing Magic Lantern is unofficial, not supported by Canon, and carries the risk of bricking the camera or voiding its warranty.
