After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the SNES native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 30 FPS for a total of 28083 frames or a Console Time of 15:36.092. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on the frame that Peach appears outside of Bowser's Clown Car.
