I just went for it. btw I almost forgot Yellow Switch but I returned for it after Iggy. Also everything that could go wrong in the run went absolutely wrong, lol.

After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the Super Famicom native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 60 FPS for a total of 98221 frames or a Video Time of 27:17.017. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on first frame the last Switch is shown pressed.

I use Nintendo Super Famicom Model No. SHVC-001 with a generic flashcart cartridge with "Super_Mario_World_Arcade.sfc" ROM loaded and GV-USB2 Capture Card.
