i dont know how to put in the codesssssssssssssss!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
But go to the shop, and when youre at the shopkeeper screen press A three times fast or until it shocks him, then put in the code. You can only use one code at a time so you'll have to shock him 5 times.
