F-Zero X is the 3D sequel to the popular SNES hovercraft racing title. It offers a wide array of cars, tracks and play options, and has had an active speed-running community (http://fzerocentral.org/f0/viewladder_10.php?ladder=2) since its release in 1998.
This TAS completes the 6 tracks of the Jack Cup in time trial mode, where you choose any track to drive solo aiming for fastest possible completion of 3 laps according to the in-game timer, accurate to the millisecond. A special input sequence is used to unlock all cars (you normally unlock cars by playing in grand prix mode).
This TAS saves 1'10"614 (in-game track totals) over the previous Jack Cup TAS (http://tasvideos.org/2314M.html) by Lord Tom (http://tasvideos.org/LordTom.html). For a per-track comparison, check the author's comments (http://tasvideos.org/5203S.html) .
