When a video game is fully mastered, players quickly invent their own challenges. Super Mario Bros. and DOOM are two of the most common examples, but today we turn to Mike Tyson's Punch-Out!!, the classic NES boxing title that debuted in 1987. One of the most extreme speedruns is defeating Iron Mike in under two minutes, something previously thought possible only with external tool assistance. However, historian, YouTuber and world-record specialist Summoning Salt finally landed a knockout in 1:59:97, brushing perfection…
I admit it: I was never good at Punch-Out. At first I don't have too many problems, but things get very strange and fast for my taste. Including level passwords was definitely a smart move by the developers, but even so, I know I'm part of a group of millions of players who never managed to face Mike in the final fight.
The story I'll share today isn't about those players, but about those who have fully mastered Mike Tyson's Punch-Out!!. In fact, some experts out there were looking for the father of all speedruns… defeating Mike Tyson in less than two minutes of the first round. Historian and YouTuber Summoning Salt is one of them, and after five years of grinding, he did it:
Punch-Out: The madness of beating Iron Mike in under two minutes
Summoning Salt admits he should feel a bit more excited about his achievement, but once we know the context, his reaction is understandable. On one hand, this world record required approximately “75,000 attempts in almost five years”, equivalent to about 41 fights per day. On the other, the probability of knocking out Mike Tyson in under two minutes is very, very, very low.
Summoning Salt explained in 2017 that the fastest technical knockout for Mike Tyson requires landing “21 perfect hits within the frame” throughout the fight, each with a window of just one sixtieth of a second. If the player hits early, they deal less damage. If they hit late, the fight takes extra time, and if the punch arrives too late, Mike blocks it.
At the same time, the player must dodge everything Mike throws their way and reposition Little Mac as quickly as possible for the next attack. In that maneuver, Summoning Salt came within seven frames of perfection, losing 0.35 seconds. Finally, there is a random factor: during the fight, Tyson can take anywhere from a fraction of a second to eight seconds to chain two punches. In his final fight, almost all of Tyson's pauses landed at the minimum of eight frames (0.4 seconds on the game's internal clock).
In short, Summoning Salt calculates that Mike Tyson can only exhibit this behavior once every 7,000–10,000 attempts. What's next? A perfect fight under tool-assisted conditions sets the time at 1:58:61. There is more than a second to improve…
