Supercard dstwo cheats

How do you disable them? For some reason when I access the DSTWO menu in-game, my pokemon black game freezes.I didn't know whether or not to put this here, or Technical Help,

When selecting a game,press X and turn cheats from 'on' to 'off'.
Technical Help is used for games and Anti-Piracy.Flashcard Help works with flashcard file system,getting started,problems with flashcards (duh) and overall related things.
Have a nice day.

thanks. could you also tell me maybe why when im walking in the grass random wild lvl 100 pokemon are appearing? D:
