Watch it here
F-Zero GX runs epitomize some of the most impressive aspects of speedrunning: relying on split-second timing, using exploits to circumvent developer intentions, and going really, really fast. By their nature, racing games are great for speedrunning, but the blistering speeds attainable in GX, and the skill it takes to reach and maintain them, are about the closest parallel to the intensity of real-life F1 or Nascar racing that one could possibly get in video games.
Most of the tricks that make GX so exciting to watch are about testing your luck for the sake of going faster. "Boost shifting" means playing chicken with the edges of the track, temporarily gliding off it then back on a few frames later for a speed boost. One course has you detonating all the mines you’re supposed to avoid so you can go faster than intended, all while managing your health in healing zones between detonations. Even someone as practiced as CGN can't do this run perfectly in front of the cameras--but when you think about the tricks he has to pull off, it’s hard to blame him.
