[TAS] NES Super Mario Bros. "warpless, walkathon" by Mars608 & HappyLee in 25:19.23
This is a tool-assisted speedrun. For more information, see http://tasvideos.org/2676M.html. TAS originally published on 2014-08-25.
Bowser has kidnapped the princess (again) and Mario must save the day. But this time through, he takes a stroll. Nothing bothers Mario as he walks through all the stages, sometimes backwards, on his way to save the princess.
This movie demonstrates that it's possible to complete every single stage without pressing the B button. Having been bothered by the lack of running and shooting in this game, the ending outright asks the player to press B.
This movie also improves the previous one by 9.31 (560 Frames @60.098813897441 FPS) seconds through new strategies and better optimization.
The authors have provided a comparison encode, which is available for download at Archive.org (https://archive.org/download/supermar...), and as a YouTube stream (http://www.youtube.com/watch?v=TzNhbg...).
This run can be played back on a real NES console, watch that here! (https://www.youtube.com/watch?v=yojQH...)
