Ruins of Alph??

uhhhh....Will it work on CRYSTAL???

That's the ONLY version you can get to the secret rooms in. In Gold and Silver, you can get the Unowns there, but that's all.

I meant Ho-oh and Lugia.The non-burnt tower suicune was in so....idk

Just go up the stairs that Suicune was standing on.
