After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the NES native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 60 FPS for a total of 9961 frames or a Console Time of 2:46.017. First Frame set on the frame "400" appears in the top right corner after selecting 1 player and End Frame set on the frame all sprites are invisible after touching the axe in -3.

I use Nintendo Entertainment System Model No. NES-001 with "N8 NES Everdrive" generic cartridge with "Super Mario Bros. [J].fds" loaded and GV-USB2 Capture Card. Console check at the end of the run.
