Four Different Super Mario Bros. Games Beaten Simultaneously

Mike Minotti: Impressive...most impressive. I've seen my share of speed runs, but never four of them running off of the same input. Specifically, four Super Mario Bros. games -- Super Mario Bros., Super Mario Bros. 2, Super Mario Bros 3, and Super Mario Bros.: The Lost Levels -- being run from one ROM. When one Mario jumps, they all jump.
