Where can you access to the Nintendo Event?

You have to have been at a Nintendo event to get access to Birth Island.

you have to go to a Nintendo event must have access to the mystery gift)

Wherever Nintendo is at for said event

a Nintendo event is a real life event that you go to get a item for a game

The Pokemon ho-oh can only be caught when given a mystery gift from a Nintendo event. This event item also gives u access to Lugia.

Regirock, Regice, Registeel, Latios, Latias (Nintendo Event), Groudon, Rayquaza, Jirachi (Nintendo Event), and Deoxys (Nintendo Event).

you can't. not without cheating or a Nintendo event to get a special ticket to gain access to the island on which it resides, only legit way i know of is to trade it from Pokemon Colesseum for the Gamecube. yes you can, if you have a mystic pass which can be abtanded in a Nintendo event

So far, there is no Nintendo event to get Arceus for your DS or DSi.

wait for a Nintendo event and go to one!!!!!!!

The time and location of Nintendo events will be announced by Nintendo.

its from a Nintendo event not a mystery gift and you get it from a event hosted by Nintendo

Victini is a Pokemon only available through Nintendo Events or trades. If you got the Liberty Pass (from a Nintendo Event), you can access Liberty Garden, where Victini is in the basement of the lighthouse

It's a download item from Nintendo. Unless you were able to access the wifi event when it was active, you're out of luck.

it depends on what event you are looking for.YOU CAN GO TO A NINTENDO EVENT FOR ANY EVENT darkrai,shaymin and arceus can be gotten via Nintendo event
