no
U cant unless u beat the 4 people and then u can duplicate Pokemon and certain items
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 clone Pokemon and items on diamond and pearl and platinum, but you can in emerald!
the only way i know is to get Pokemon emerald and duplicate Pokemon holding rare candies(go to youtube to find out how)and migrate them to your game
It is rather unfortunate that you can not get Deoxys in Emerald, however, it is possible if you go to a Nintendo Event.
Its not possible to get any other way.
It is not possible to catch Mew is Pokémon Emerald version without using cheats. The only way to get it would be to trade.
i don't have emerald but the valuable Pokemon is rayquaza
how to get all the tickets in Pokemon emerald?
I dont know maybe you should ty serebii.com
Action replay codes.
