Super Mario Bros.: Superfast Mario Bros. is a fan-made hack for the Nintendo Entertainment System that modifies the original game to achieve extremely high speeds. The framerule is altered to allow instant acceleration and nearly instant level completions. While the fast scrolling can lead to minor graphical glitches, it does not significantly impact gameplay. Originally designed for a tool-assisted speedrun, it has proven to be playable as well.
The framerule was changed from 21 frames to 1 frame, instant acceleration to 0x7F speed, various delays cut out or speed values increased, nearly instant level clear.
It's about as fast as acmlm could make it go, and was meant mostly for a silly TAS, but turns out to be actually beatable too!
Superfast scrolling sometimes causes slight graphical corruption, but it doesn't affect gameplay (mostly).
