I'm a veeeeeery careful owner of consoles and I treat my 3DS XL most gently; it's in one of those super bulky protection cases and everything and it's got screen protectors on. I guess that I've just been playing it quite a bit since Smash came out and this problem has gradually become worse wherein if I slide the circle pad left, right, or down, it doesn't slide back to the middle. Well it does, but not all the way. Today it's reached a point where Smash is unplayable and I'm really upset. i.e. if I'm walking left and then I'd like to stop, my character would just continue walking left after I'd let go. I'm sure you guys can see 100 different ways this is problematic. What should I do? I don't live in a region where Nintendo service centres or whatever exist so if I'm gonna send it for repairs it'd have to be at some dodgy game store, which I don't really want. I'm open to DIY suggestions if they're feasible. Does my circle pad need replacing? Should I just spray the underside of the nub with WD-40, or is that harmful? Has anyone else come across this issue?
