First to get the Ruby you have to beat the Elite 4 then go to Mt. Ember. There will be two Rocket Grunts battle them and win then they will leave. Go into the cave keep on going on the paths to get to the Ruby. And to get the Sapphire go to the Dotted Hole and use Cut on the Entrance then do this pattern, go to the middle, then go, up, down, left, then right I think if I am wrong mix it up eventually you will find the Sapphire. Then you can trade with your friends if they have a link cable and Pokemon Ruby, Sapphire, or Emerald.

Have fun with it!
