Your Nintendo ds wont read your games how do you fix this?

blow a pressurized air to the slot1(blow it a bit hard but don't let your saliva come out duh..)blow it for like 2-3 seconds before you insert the flash card

while inserting the flash card, keep blowing harder and harder until the flashcard is locked

notice:look for dust,dirt, or a broken pin first in your 1st slot..

just take a clean cloth and rub it on your flash card ANDslot(don't bend the pin though)

if there is a broken pin, go to the store you buy the ds or the nearest store
