Piotr Delgado Kusielczuk, better known as The Mexican Runner or TMR, is a speedrunner who specialises in Nintendo Entertainment System (NES) games.
After three years, on February 26, 2017, TMR was the first player to play through the entire NTSC and PAL NES catalogue,[1] completing 714 officially-licensed titles in a project he called NESMania, which earned him a Guinness World Record.
While speaking online with fellow speedrunners from Chile about the stressful situation regarding his mother's health, they sarcastically suggested that he should play the entire NES library.
He decided it was a good idea, and on May 28, 2014,[15] he started streaming a complete playthrough of the entire licensed NES library, beginning with Whomp 'Em.
In one instance, when playing the Elite port to the NES, a member of the online audience contacted Ian Bell who suggested a winning condition.
Around April 15, 2016 near game #395 (Might and Magic Book One: The Secret of the Inner Sanctum) a modification to the self-imposed rules became necessary when he learned that another runner was also attempting a full completion of the NES library, but using extra outside help with hints and spoilers,[16] which greatly reduced play time.
[18] In an interview with the Mexican publication LevelUp,[19] TMR explained that despite being a musician, learning how to play the piano was challenging as the game's difficulty continuously increased the required coordination between the two hands, demanding ever more skill.
[20] Also just two days before the finale, Waypoint of Vice Media[14] noted how TMR found Ikari Warriors to be one of the most punishing games and required using save states on an emulator in order to practice, discovering glitches and other speedrunning techniques along the way.
[21] The official record reads, On 26 February 2017, Twitcher "The Mexican Runner", aka Piotr Delgado Kusielczuk (Mexico) finally completed a near-three-year quest to finish every licensed NES game ever released: a total of 714 titles.
[27] The two-player run is of particular note because neither player can be certain by audio cues alone of who made a mistake and lost a life, and both have to start over from the last checkpoint if either loses.
TMR also remarked that in the blindfolded category the exact height that the player character is on-screen is difficult to know, as it depends on the amount of time the up and down arrows on the gamepad are pressed.
