My Nintendo DS does not work right. It says there

Have a look down the game slot for any bent or broken pins if not the slot 1 game socket is not holding the game cartridge tight enough to the pins to make a good connection. there is a quick fix for this that has worked for me, only if you are confident enough to open up the ds, by pressing down hard enough to make a slight dent in metal peice on the logic board, press down the bottom corners and the middle with a small screw driver and that should cure the problem. good luck <tell me how it goes>
