well there are 2 things i did to solve the problem; 1: super glue the crack 2: get a same or different color backing, take the old cracked one off by using a thumb tak and get those little plastic screw covers off, next take the screws out and put them on a white pice of paper, then grab the front half with your thumbs on the smooth side and push up with your thumbs, then lift the back plate up and off the DS and TA-DA! you got the back off now get the new one and put it on the oppisite way you took it off.
