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 30 FPS for a total of 7070 frames or a Console Time of 3:55.662. First Frame set on 1 Player Select and End Frame set on the frame Mario is fully visible inside Princess' chamber and the game does not crash.

I use Nintendo Entertainment System Model No. NES-001 with "Super Mario Bros. 3" cartridge Model NES-UM-USA-1 and GV-USB2 Capture Card. Console check during the credits.
