NES Super Mario Bros. TAS in 04:57.31 by HappyLee

This is an 1-frame improvement to one of the most unbeatable movies on TASVideos. The route I've selected is perfect in both speed and entertainment, at leas...

For the uninitiated, it represents a theoretically perfect speedrun where someone manually enters the exact required inputs for each individual frame.

It hasn't been beaten in over a decade, and RTA speedruns are inching closer and closer to this "optimal" time: the current world record ties the TAS in all levels except the last one, largely thanks to the so-called framerule system.

This resolves YES iff a (non L+R) TAS, generally accepted to be legitimate, is published to TASvideos, Youtube or some other public website which completes the original Super Mario Bros in strictly less time than the current TAS posted above.
