The online parts if for people not to use cheats in an online game , if use a Always first place in Mario Kart , you will be cheating online .I dont get the online part. Thank you for your codes anyway.
But if the cheats are for a previous version , when you want to play online , the game will be updated and the cheats will not work , and you wont be able to cheats online , in base version you will always be able to use the cheats offline .
