After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60. which is the Switch native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 60 FPS for a total of 44221 frames or a Video Time of 12:17.017. First Frame set on the frame Mario appears in the intro and End Frame set on the frame the last coin on Phase 23 is collected.

I use Nintendo Switch OLED Model HEG-001 with "Game Boy Advance - Nintendo Switch Online" version 1.11.0 and a generic HDMI Capture Card.
