M3 freezing???

Okay so I have an M3DS real and as of late its started freezing a lot and I'm not sure if its just the roms I have or maybe the M3 itself or what but has anyone else had this problem or knows how to fix itt?

Has it worked before?How old is the card-they can start to waer out on account of them being cheapy made-my acekard 2.1 is starting to give.What games-and if possible-are they from here?

Its not the old I got it in like April and the main ones that freeze are Pokemon Ranger and Spectrobes and other freeze every now and again. And yep the roms are from here

Try this for details :)
