Items can not be doubled in Fire Red. There is a massive glitch in Emerald which allows mass production cloning of items however, and its possible to trade between Emerald and Fire Red if you wish to try.
You can't :/
some items are used during pokemon trading.
give 'em 2 ur migrating Pokemon from saphirre, leafgreen, firered, etc.
Moltres, Zaptos, Articunoe, and Mewtwo. Ho-oh and Lugia if you have 2 certain Nintendo Event items, or if you use a Gameshark/Action Replay.
Check if it is holding a specific item. There are some rare items which stop evolution when held. That's all I can think of =/
from what i know, you can't. srry. :) but you might get lucky and find someone. from: flyguy007 Hi this is flyman1111 i think you can duplicate items in Pokemon platinum all you have to do is get a ditto and a Pokemon with thief make sure the Pokemon with thief is holding the item you want to duplicate then you get into a double battle use thief on ditto and ditto will have the item that the Pokemon with thief has =] hope it has helped and worked
NO...VERONICA
There are 3 ways to get ditto in Pokemon diamond. 1. You CAN catch a ditto in Pokemon diamond. I just forget where. 2. Migrate on from FireRed or LeafGreen. 3. Use an ar code that I forgot...It's a code to get 493 master balls in the items pocket. You throw away enough(in this case you throw away 361 to get ditto.)to get to the number of that Pokemon in the pokedex.
Yes
FIRST you get a ditto and a Pokemon that knows thief go into double battle in Pokemon tower(north from fight zone) and have thief as first Pokemon and ditto second(so they both go first) make your thief Pokemon uses thief them make your ditto transform and win the batlle the retire and save then you have the theived item twice unfortunetly this doesn't work with your items in your bag BYE BYE. =)
somehow
Well.... there is only one way to duplicate rare candies, masterballs, and other items. Take two Pokemon different gender but same species, or one gendered species Pokemon *No ledgendaries* and one ditto and take them to island 4 *after beating elite 4* and breed them with the day care people. The man outside will be standing out a little bit, after you have waited a while. He will give you an egg which should contain the item held by the one Pokemon after it hactches!Answer 2:im not sure if this is true.But i heared that if you go into a double battle with a ditto and another Pokemon, you should give the item you want to duplicate to ditto and another Pokemon needs thief.once in a double battle you can use thief on ditto and ditto should still have the item and do would your other Pokemon.
