yes you can but the only other way you can is by AR or you could get lucky at the pokemon lottery.
if you clone a masterball
No you can not have more than one login in Pokemon diamond.
Go to superheats.com and use the AR code or trade som1's Pokemon that is holding the masterball
if you draw a lottery ticket in the lottery corner in jublife city and the number matches with one of your pokemons I.D numbers she will give you a masterball
The only way you can get more than one masterball on Pokemon ruby/saphirre is you compeate in the Pokemon lottery corner. In Pokemon emerald you can have a Pokemon hold a masterball and then clone it.After you beat Team Rocket in the Silph Co. building, then the president at the top floor, after you beat Giovanni, will give the Masterball to you.
i would use an action replay other than that i dont know
the guy that wants a Pokemon and gives u a masterball is the newspaper dude in solacean town next door to the Pokemon centre but it must be persific Pokemon but u can only do this once a day and each time u do it he might give u other pokeballs than a masterball
Since the Masterball has a 100% catch rate, receiving more than one would make catching Pokemon irrelevant, so you will need to plan which Pokemon to catch with the Masterball.
I believe that Pokemon platinum is better than diamond and pearl because it offers more features, and allows you to do much more cheats and tricks and get more Pokemon through normal game play than Pokemon diamond and pearl. Yes, it is.
This wont work, but you could try having to Pokemon hold Masterballs and mate them. Hope it works!
The easiest way would be through cheat codes, but the legal way would be through the Pokemon lottery.
no no
