Beat the game gran prix with every character on everything and get time trials under a certin time, if u complete this u will get a track called Nintendo endrence. it will be every level but one lap, they will all connect. for example once u finsh one lap at toad's turnpike, u go into superspeedway

to change anyones's clothes color... do the same thing mandos said but with the character u want to change

unlimited red shells. if u get more than 3 batches or 3 shells in one race and everyshots hits a person. u will get unlited red shells as a option

get stars longer (time of length) get 5 stars in one race. u get an option u can turn on or off

does it really? if it does u should really edit ur post and tell that becuase people might actually try it...

get a new battle couse...

get every item once in one race. after u will get a new couse when u check it...

do u think it works all the time or it jus messed up on u becuase that code u made is very random

to get go kart damage (reduces speed ect)

don't hit a car (other karts) or don't use an item the whole race in a series 9must win the seris) after u should get a sing that say damage on the left of the screen. u get an option to turn on /off

the only thing is that mew isn't even in this game...
