Diddy Kong Racing Nintendo 64 game cartridge Each world contains several race tracks, an unlockable battle stage and a race against a boss character. Depending on the race track, players may have a choice of using a car, hovercraft or plane; this choice is restricted on some tracks. Each race track contains Zipper devices that give a short-term speed boost to racers that cross them, and balloons of various colours that provide powerups to racers. If the player beats Wizpig in Future Fun Land and obtains the amulet pieces and gets all of the gold medals, the player will be able to play in a mode called Adventure 2. In this mode, all of the balloons are silver and the tracks are flipped from left to right. The silver coins are in different locations in each track, often in harder to reach places. The opponents are also significantly better, but other than this the mode remains the same.
