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 22638 frames or a Console Time of 12:34.591. First Frame set on the frame the hand chooses the first level and End Frame set on the frame the score screen starts to fade.

I use Super NES Control Deck Model No. SNS-101 with "Super Mario: Yoshi Island" cartridge model SHVC-YI and GV-USB2 Capture Card. Console check at the end of the run.
