Niftski breaks Super Mario Bros. speedrun world record, two frames shy of theoretical limit

The new any% time beat Niftski’s previous record by 33 milliseconds. It sits two frames behind the 4:54.265 tool-assisted benchmark, which follows the rules for human runs. A faster tool-assisted time uses inputs banned from human attempts. Niftski and LeKukie are both chasing a tie with the benchmark.
