So I haven't played my 3DS for some time now, and neither my brother nor I realized we needed to put in a Micro SD card until now. It wasn't a problem then but it requires now and when I did inserted a Micro SD card, it was loose. Like I can more around and shake it out. I was not too sure if they are supposed to loose or not but when I looked up on YT, it was supposed to easily insert it in and fit.

So is there any possibility of it being fixed? Current? Or am I screwed.
