id Software Super Mario Bros. 3 PC Port Prototype
It’s true, Super Mario Bros. 3 was set to arrive on the PC back in 1990 at the height of the NES game console’s popularity, but unfortunately, the port was never released. John Romero, co-founder of developer id Software, uploaded never before seen footage of the adaptation, and let’s just say that it stays true to Nintendo’s side-scrolling formula. Read more to see a demo completed on September 28, 1990 from IFD (Ideas from the Deep), the company that preceded id Software.



Nintendo was quite impressed and didn’t approve of the adaptation solely due to the fact that the Super Mario Bros. intellectual property could only be used on their own hardware. So, Ideas from the Deep (IFD) / id Software then went on to develop the Commander Keen series for MS-DOS in 1990, which ended up even getting a release on the Game Boy Color in 2001.

We worked on this demo for a week, after work, and on the weekend all two days. However, they didn’t want their intellectual property on anything but their own hardware, so they told us Good Job and You Can’t Do This,” said Romero.
