#MARIO KART 64 WAD JAPAN SERIES#
This is the first game in the series to provide this feature. There is an additional unlockable difficulty called "Extra", which allows players to race at speed 100cc on tracks that are inverted left-to-right.
Difficulty level is measured by engine size: 50, 100, or 150 cc. 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. Unlike the original Super Mario Kart, the player can restart an unlimited number of times, instead of only being allowed three restarts. If the player ranks 5th or under, the player must restart the race. When the player completes a race, points are awarded based on the rank they finished ranging from one to nine and the placement order gets carried over to the next race as the new starting lineup.
