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 17970 frames or a Console Time of 9:58.997. First Frame set on first Mario sprite during intro cutscene and End Frame set on the frame the coin counter increments in 1 indicating the last shell has been eaten.

I use Snes9x 1.60 with "Super Mario World [J]" ROM.

I time my runs manually with LiveSplit during gameplay.

I use Retroflag USB Gamepad controller and NintendoSpy as Input Display.
