Yes, you can. Since Pokemon included in HG and SS are from previous generations and HG, SS, DP&P are all in Generating forr, DPP coming first, yes.
Sorry, but you can't. You can trade from LeafGreen to Pearl, but not back.
No. Just like in Pokemon Pearl with the Pal Park you can only trade from Pokemon pearl to black, not back
get giratina give the girseous orb to it and trade to a Friend and trade it back to diamond or pearl
Yes, it is possible to trade items in Pokemon Pearl but, this is only allowed if you trade the item when it's attached to a Pokemon. If you are trading with a friend and don't want him to have your Pokemon just trade back.
You need to get the National Pokedex. Then use Poke Transfer. But you don't get the White Pokemon on Pearl. You can never get the Pearl Pokemon back to Pearl.
Trade while holding a protector and trade back
Attach the item to a Pokemon and trade it then get your friend to take the item off and trade the Pokemon back
You have to make your Pokemon hold the item you want to trade,then trade the Pokemon,if you want the Pokemon back them have them take the item and trade your Pokemon back to you.I hope this helped!Have fun playing Pokemon Diamon and Pearl!:D
You must trade it to another NDS and then trade it back to get Alakazam.
you can convert pokemon from diamond, pearl, soul silver and heart gold to black and white but first you need to beat the elite 4, N and ghetsis then a place will open up where you can transfer them to white or black, BUT, you can't send any pokemon back to silver so it's basically the same as pal park on pearl when you get pokemon from ruby saphire and emerald. just make sure you know you want them there otherwise that's it and you wont get them back. :)
Okay i have all those i actually have like 3 or more but i will add you but i have Pokemon pearl and I'm not sure if u can trade from soul silver 2 pearl but anyways i have the Pokemon you are looking for
