The only one i can remember now was footbag, cause i noticed there that it only had a 16 bit counter for the score (it looped over 65000 points). It still counted as the highest score though even when some 'higher' scores were visible :)
What i remember of BMX was that if you managed to bounce clockwise instead of counterclockwise normally (by landing on your frontwheel when going downhill) you could get a Lot of points, if you didnt end up in some ditch again that is.
