There isn't any Passwords in the Games. There is some Cheats.
No, pokemon rumble blast have his own passwords you can check all of them in http://serebii.net/rumble2/passwords.shtml NOTE: there are american passwords, pal passwords (europe and australia) and japanese passwords, put the codes of the game you have for example you cant put japanese passwords in american game.
there are no passwords in diamond, pearl, or platinum
I HIGHLY doubt Pokemon Pearl AR cheat codes will work in Pokemon Platinum =]
yes it will work with any Pokemon
An action replay DS does work on Pokemon Diamond & Pearl I use it all the TIME!
It changes the wild pokemon that appear in the game.
Yes it does!
no there is not a cheat for that but there are other cheats
yes there is there is lots some don't work but i suggest supercheats.com (25 pages of AR codes for Pokemon pearl and dimond!) NOTE imond codes work for pearl!!! And i suggest neoseeker.com too. HAPPY CHEATING :)
For most routes, the pokemon be the same. But a couple of routes will be different compared to diamond/pearl.
Once you chase Pokemon of lake you see where they are
A maid in Pokemon mansion will give one to you THIS DOES NOT WORK
