Since a few days, my 3DS has been having some pretty big crashing issues. They are particularly consistent with two recent games: Kirby triple deluxe and Mario golf world tour. With kirby, the game crashes every single time that I exit the keychain menu, showing the following message "An error has occured, forcing the software to close. The system will now restart. (Unsaved data will be lost.)". It happens also 80% of the time at the beginning of the Mario golf intro cutscene, only way to be able to play is to either skip it or get really lucky. It also crashed multiple times randomly during gameplay. It also crashed in find mii some time. I have this pokemon Y design XL 3DS since october, and I've been taking care of it. It's really worrying me, what should I do?
Thanks.
