I've been playing Platinum pretty much nonstop for about three months now, which has been awesome but of course are some pokemon that I just can't get in Gen IV so my boyfriend ever so helpfully found a copy of Ruby, but he got it at GameStop and it stll had a game data on it.
There were only like 60 pokemon in the pokedex but all 8 badges had been earned so pretty much all the areas have been unlocked. Last night I was trying to go get the three Regi pokemon so when I looked it up it, Bulbapedia said I needed to go to route 134 and dive to the Sealed Chamber with a Relicanth in the front of the party and a Wailord in the back and when you enter the second room there is supposed to be an earthquake and the door opens. So I had to catch a Wailord and a Relicanth And I tried it and nothing happened. I tried several things (switching the order, circling the room clock wise, counterclockwise, looking at the Braille, not looking at the Braille, not moving at all; reenetering each time)
I've checked the Desert Cave where Regirock is supposed to be but it is still sealed. I don't think the previous owner did this already because I was the one how caught Wailord and Relicanth because the pokedex recorded them then and none of the Regi pokemon are in the pokedex either.
What am I missing or what haven't I done? I just don't know.
