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.
