After beating Giovanni at Saffron City IN the Silph Co. building, talk to the president and he will give you a master ball.
You give the Ruby to Celio and you'll receive the Rainbow Ticket. Then get the Sapphire Gem. Once you have it go to Island 1 and give it to Celio. Then he'll say, "Yey finally the machine is operating". You can then trade from ruby, sapphire, emerald, colosseum and XD.
In order to get to Cerulean Cave where Mewtwo is, you have to obtain the national dex from oak(after beating elite 4) and both the Ruby and Sapphire Gems.
To catch Mewtwo:
Make sure you buy lots of Ultra Balls before you go into the cave. Save before you fight/catch him. Work its health down and put it to sleep(putting him to sleep wont work if it uses safeguard though). Then start using ur Ultra Balls. Or if u want, use your masterball. But, I would save it for your dog or Ho-oh/Lugia.
