Pokemon Y problem

First of all hi there,its my first post here.
Now lets get to it,my problem is that when I get for instance a pot or when I win the first combat at the start of the game the game “freezes” with freezing I mean that I can still see stuff moving on the screen but I can`t do nothing,even pressing all of the buttons (I may be retard and it may be my fault)anyone knows a solution?

And my second question is,how do I save the game,or it saves automatically?

Thanks

Pokémon X and Y are not playable now, you should search before posting (this was asked 12748912961235 times already). To save you do as you do in the 3DS, it’s the same game

Gotta go with Sun and Moon,thanks for the info
