I am not sure how it happend but the "A" button messes up, I still responds but it still messed up.
In "sims 3 pets" if I press "A" to choose somthing I have to press the button a few times for it to work.
In "mariokart 7" my kart goes slow then speeds up but keeps slowing sometimes and it cancels my drift sometimes.
I tested a few other games and it seems like it is most likely the 3ds/button and not any of the games.
How do I fix the button to make it work properly (without opening up the 3ds in anyway) the "A" button makes it take longer to choose somthing and slows my kart down in mario kart.
