You take the Arceus from Spear Pillar from Diamond/Pearl/Platinum to the Ruins of Alph.
No, Sinnoh is not available in HG. But, if you have the Event Arceus, you can go to the Sinjo Ruins.
There are no Sinnoh ruins in the entire pokemon world. If you mean the Solaceon Ruins in Sinnoh, you can't go to sinnoh in HGSS. If you mean the Ruins of Alph, they're between Routes 32 and 36.
you meet Cynthia by going to the sinjo ruins (show an arceus to the president at the ruins of alph) and she will help you get a sinnoh legendary egg (Palkia, Dialga, or Giratina) amd then the unown will warp you back to the ruins.
Get event arceus talk to ruin excavate team leader go to sinjo ruins and get an egg there of a legendary and no I'm not psyco but then you can go to sinnoh
No, because the data for the new Pokemon isn't in HGSS, so the programmers have to keep all Pokemon from being traded into HGSS. You can import your Pokemon from HGSS to Black and White, though, you just can't trade them back.
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
