In 2015, John Romero shared a video showing a demo id Software developed in 1990 to sell Nintendo on the idea of a PC port Super Mario Bros. 3. Nintendo continued to reject the field of study, but the code that John Carmack developed to allow the game to move smoothly on the computer continued to play an important role in Commander Keen’s next games. That piece of game history has now reached Strong National Game Museum.
The museum said she recently received a demo as part of a larger donation. It came on a floppy disk of a developer unrelated to the original project. Curator Andrew Borman says he recorded the disc to preserve it as a physical artifact and that he used DOSBox and Romero’s video to check what the museum has in his hands. “Since we’re such an early demo, it’s a lot of fun to play, especially 1-1, which creates that cult first level out Super Mario Bros. 3,” he said Ars Technica.
Currently, the Game Museum has no plans to display the demonstration to the public, although Borman noted that there will be “many opportunities to come in the future.” Meanwhile, researchers may be asked to study a rare part of the game’s history.
