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 00:10.82 seconds through new strategies and better optimization.

The authors have provided a comparison encode, which is available for download at Archive.org, and as a YouTube stream.

This run can be played back on a real NES console, watch that here!
