The ruby is somewhere in mt. Ember, to get the sapphire use cut on the door to dotted hole, in ruin valley on six island, then fall through the hole inside the cave, then fall in to the holes accordingly, top hole, then left hole, then right hole, then bottom hole. Now you find the sapphire, when u try to take it this team rocket scientist geek comes and takes it, but gives you the second password to the team rocket base. Then u can go to the team rocket base and beat the rocket nerds for ever, give the ruby and sapphire to celio, and go to cerulean cave in cerulean city to catch mewtwo easy peasy with a master ball. (if you dont have a masterball save in front of mewtwo and switch the power off and on if you run out of balls or kill mewtwo)

The Ruby is at Mt. Ember. When you enter Mt. Ember, go to the right and you will see 2 freggin rockets. They will talk about something then go near them and talk to them. BEAT THE HELL OUT OF THEIR POKEMON!. Then go inside. Then, continue down the path till you see 2 paths. Go down then the ruby is there. I dont know the sapphire.
