I don't think you can. You can get Max Items with an Action Replay.
you cant really do it. it just messes up your game
Item BoxesYou can't store items in Pokemon Diamond and Pearl. The Item boxes were only for the older games. Now, to store items, you can just give the items to Pokemon stored in the PC.
This is not possible without Action Replay. There is a code that can duplicate Items and Pokemon, but if you mess up on one of the steps, then your game might either freeze or turn off. So overall, it's very risky.
You Cannot.
Use action replay or keep making new game on pearl and transfering items.
pale spheres there rare in pkmn diamond not so much pearl if you are trading a pale sphere from pearl the best thing is a prisim sphere its rare in pearl and common in diamond
No.
you can. it's just the same as duplicating a Pokemon, but make sure your Pokemon is holding the item you want to duplicate. =)
To multiply items on Pokemon Diamond/Pearl, you need the action replay. Unfortunately, if you have the DSi, the action replay won't work. It only works for the DS. If you want to 'multiply' Pokemon, breed them by leaving a male and female Pokemon in Solocean Town Daycare Center. Possibly, they could lay an egg!
Yes. look it up plz i had it once
if there attached to Pokemon
It isn't in Pokemon leafgreen. It is only in Pokemon Diamond, Pearl, or Platinum. I suggest actually knowing where items and buildings are and knowing which games they are in...:P
