Currently obsoleted by Periwinkle's run.
I apologize for double-uploading. There was a 2-frame improvement in World 8-4 that I overlooked.
While it’s (possibly) not a popular goal, Super Mario Bros. actually can be completed without collecting any coins. My run aims to do so in record time.
This is also an improvement of 0.81 seconds over the previous TAS by MarioUniverseZone mostly due to a faster strategy of entering World 1-1’s underground bonus room. Some of the improvement was also from despawning the Piranha Plant in World 8-4’s second room.
