No, Sinnoh is not available in HG. But, if you have the Event Arceus, you can go to the Sinjo Ruins.
no ure supposed to take arceus to the ruins of alph then you will go to the sinjo ruins ,talk to cinthea and she will walk off then follow her then u will get the choice of a level1 palkia, level1 giritina or a level1 dialga. :-1
The Arceus that was given away for the Sinjoh Ruins event in HG/SS was given away in Japan from 7/18/09-9/30/09 and in North America from 9/7/09-9/15/10. The Arceus event in now over.
somehow get arces then go to the ruins of alph and go into the lab
It is in one of the chambers in the ruins of alph
if its the arceus from Sinnoh then you will trigger the arceus event which is awesome
you need a arceus then go to the ruins of alpha. if you do not have a arceus then your out of luck.
Have Arceus as the main Pokemon in your party, and then go to the Ruins of Alph and head towards the Research Lab, where a researcher will bump into you, and lead you there.
Arceus
no
Arceus
I heard that if you migrate an arceus to soul silver/ heart gold you can get like giritina, palkia, or dialga some how. that's all i know.The Way To Do That Is Go Into A House At The Ruins Of Alph And He Will Bring You Somewhere.
get an arceus of platinum and trade to soulsilver then go to the ruins.
you can but you need an arceus then go to the ruins of alph into the small lab and then you can get a giratina,digla, or palkia
trade over your wifi arceus to hg or ss and put it first in your party. Go to the ruins of alph and try to go into the building with people in it. the older man will take you into the ruins and then the event happens
You have to enter through the entrance near a house and arceus has to be in the first slot.
you bring event arceus and go to the house and be shore arceus is only Pokemon in your party and play rest by ear to get to a special ruins and get dialga, palkia or giratina at level 1.
