Easy Breeding If you capture a Ditto you can use that for breeding. The Ditto will act as the female, so you wont have to get two of each type of Pokemon that you want the baby form of it. For Example just breed a Ditto and a Pikachu, and you will get a Pichu.
Duplicate Pokemon You can duplicate pokemon whether or not it holds an item. Get to a computer and save it, making sure that you have atleast one more room for the cloned pokemon. Deposite the poke'mon that you want to duplicate. Now change boxes, when you change you'll automatically save, so say yes when it asks you to save. When it says "Saving, don't turn off the power", turn it off then on. When you gain control, you'll be holding the regular pokemon and there will be the cloned pokemon in Bill's PC. Use this glitch at your own risk, as it is possible to corrupt save data.
