How do you get the ruby stone at Mt. Ember?

First Thing. You'll need a pokemon with Strength and Rock Smash.

well from th first place it says you're at Mt. Ember travel North, and you should meet a man who wants to teach your pokemon Explosion.

From that man, travel up and right until you see two Rockets. you get to battle them, and once they're gone, they'll tell you a password to their warehouse, anyways, enter the cave.

Go up, left, and follow the tunnel. Take the ladder and follow that tunnel. take the ladder.

Now follow the tunnel untill you see some boulders. walk up and push it forward 2 places. walk down and right, and push the boulder one place.

Then walk up and push that boulder up one place. Walk through the rest of the tunnel and take the ladder. walk up to that boulder and push it once right, walk up, and right, then push the boulder down.

Now this is where there's a fork in the road. Right or Down? One leads to the Ruby, the other leads you in a circle. Take the down path.

You'll see a boulder, just keep moving it where you wanna go, then step to the side, and take the stairs down to the ladder.

You'll see a room full of Braille tablets. In the lower right hand side, there is a ladder, take it and there you are. hope this helps.
