SMW NES - Fixed Physics is a ROM hack of Super Mario World designed to improve the original physics engine. This fan-made game aims to improve upon the original, often adjusting elements like character movement and momentum for what some consider a more refined experience. It is not an official Nintendo product and details of the creators are largely unattributed, available mostly through ROM hacking forums and communities.
