Mark Russinovich, the Chief Technology Officer for Microsoft Azure, has created a project called DoomPaint that allows the classic 1993 game DOOM to run within Microsoft Paint. The application works by placing each game frame on the Windows clipboard and pasting it into Paint, which acts as a display medium rather than a game engine. Users need to install Python to run DoomPaint, and there is also a demonstration video available. The project involves contributions from entities like Anthropic's Claude and Microsoft's GitHub Copilot. DoomPaint features working sound and music, but it is primarily a visual trick rather than a complete game engine conversion. To enhance the experience, players need a legitimate copy of DOOM's internal ".WAD" file.
