other. Grand Prix – This mode has one or two players participate in four consecutive three-lap races, each on a different course, on one of the four selectable cups (Mushroom, Flower, Star, or Special) against seven (or six) computer players. When the player completes a race, points are awarded based on the rank they finished ranging from one to eight and the placement order gets carried over to the next race as the new starting lineup. If the player ranks 5th or under, the player must restart the race. Unlike the original Super Mario Kart, the player can restart an unlimited number of times, instead of only being allowed three restarts. After finishing all four races, trophies are awarded to the players who scored the highest accumulation of points: bronze for third place, silver for second, and gold for first. Difficulty level is measured by engine size: 50, 100, or 150cc. There is an additional unlockable difficulty called "Extra", which allows players to race at speed 100cc on tracks that are inverted left-to-right. This is the first game in the series to provide this feature. Later installments call this feature "Mirror Mode" or "150cc Mirror Mode". Time Trial – This is a single-player-only mode where the objective is to complete a three-lap race on the selected track in the fastest total time possible. There are no opponent racers or item boxes, though the player will always begin each race with a Triple Mushroom in reserve. For any given course, the top five fastest total times are saved, and the fastest single lap time of any race is also saved. The player can select to race against a ghost character, who will mimic the movement of the player from a previous race. Ghost data for up to two different courses can be saved permanently only on a Controller Pak device. However, the Virtual Console version of Mario Kart 64 released on the Wii is incompatible with the device and is thus unable to save ghost data. Versus – Two to four players compete in single races on any track without any computer players. With two players, the total number of wins for each player is tracked, and in three- or four-player matches, the number of 1st, 2nd, and 3rd place wins is tracked for each racer. Battle – This mode, supporting two to four players, has a last man standing objective
