Yes, either with the 'GTS Cloning Glitch' or an Action Replay. The latter is the easier way...
Im sorry you can't duplicate Pokemon in Pokemon platinum. You can duplicate Pokemon in diamond/Pearl or emerald the trade or migrate them to platinum though.
its is super RARE
be a man, find out yourself
You cannot clone Pokemon and items on diamond and pearl and platinum, but you can in emerald!
It can't be done.do not duplicate your Pokemon your game boy save will be delete
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's the same as any other game. Ditto+ Pokemon you want to duplicate (not legendaries)xthe Pokemon daycare= Egg. Hatch the egg and you either have a duplicate Pokemon OR the first evolution of that Pokemon.
You can't duplicate items in Pokemon. Only if you have the Action Replay or GameShark, then you can.
As far as the game goes, you can't duplicate Pokemon on Sapphire. Tried it and it glitched up.
Get a Ditto from Route 13 or 15 and breed it with the Pokemon you want to duplicate. The Pokemon you want to duplicate has to have a gender and you have to use the daycare on Four Island and Route 5.
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.
i think you duplicate Pokemon by putting the Pokemon you want to duplicate into the PC. then change boxes and while it's saving, turn it off. then turn it on. the duplicate should be in the box you changed. this works for up to 5 Pokemon.
