This is a tool-assisted speedrun, made on an emulator, using frame-by-frame shooting, savestates, and rerecords to overcome reaction time and human error. As such, it is purely a form of entertainment, and is not designed to show skill.
The third installment to the Tony Hawk series of skateboarding games.
Since there is no real use in aiming for the fastest time, emu instead opts to show off by performing crazy stunts, large combos and making a really high score. It is intended to be judged by its mastery of the game rather than how quickly it reaches completion.
