The Pokemon Platinum update for My Pokemon Ranch is only available in Japan for Japanese games.
Do you mean transfer from Platinum to My Pokemon Ranch? Unfortunately, an update for My Pokemon Ranch was released, allowing transfer, but it's only in Japan.
There is no way to receive an update for My Pokémon Ranch in order to allow for Pokémon Platinum to work with it. Nintendo of Japan only sent the update out to Japanese Wii players, an international version of the patch was likely decided to not release to English and other international Wii My Pokémon Ranch players.
There is no official date yet. :( But I bet they are working on it right now! :)
Not in the US yet, sorry. There hasn't been any confirmed dates of the update that will allow for Platinum.
Platinum is only compatible with Pokemon Ranch in Japan.
The update isn't available yet for anyone outside of Japan. More information will be announced when and if it's known.
So far only Japanese players are able to do that. No one else can. My Pokémon Ranch won't recognize Platinum without an update. Nintendo of America should be releasing the patch at some point but we just don't know when.
No, only Diamond & Pearl; not even Platinum works on Ranch.
no, unless you live in japan.
you have to use wi-fi connection
You can, but you need a copy of Pokemon diamond, pearl, Platinum.
