duplicate items
To duplicate items you must first beat the game and as soon as you have done that go to the battle tower after you get the s.s.ticket. Go to the pc and give the item that you want to duplicate to a Pokemon then save. After take the item and talk to the lady closest to the pc and go challenge but when it says saving don't turn off power turn off the power. When you turn it back on you should have the item in your bag and on the Pokemon who held the item and thats how you duplicate items.
