Mini 4 Boy — About this game
Build a miniature racing machine and climb from rank eighty toward the championship. Motors, tires, gears, rollers and other fittings change speed, cornering, downforce and power, so a faster part is only useful in a balanced setup. Buy equipment or win it from races, face category rivals and watch the circuit display to judge the result of your changes. A course editor provides a testing ground, while linked play lets two owners compare their tuned machines. Choose 1PLAY, name the driver and car, then inspect the room and machine setup. Equip parts that suit the course, enter a race and compare lap data with your earlier setup. Use the course editor under OPTION for controlled tests and save before leaving.
