You go to ROUTE 111. If this doesn't help, then give up. Also, u have 2 use a match bike. THAT IS ALL.
In Pokemon Emerald, The Mirage Tower appears randomly. All you have to do to make it appear is keep going back-and-forth from Fiery Path to the Desert and it should appear. Just make sure you have the Mach Bike, You'll need it inside the tower to get past the fragile sand floors. And at the end of the Mirage Tower, you'll get a nice suprise! :)
Beat the Elite Four, then go to the house to the left of lavaridge town, then go into the now-completed tunnel. there should be plenty of ditto in there, as well as what ever fossi you did not pick up in mirage tower.
It is not available in Sapphire, but it is in Emerald. It's in the desert region on route 111. If you come up from Mauville City the Mirage Tower will be close to the entrance of the desert area. Sometimes you can see it, sometimes you can't so just keep going back and forth until you do.

You go into the battle tower in the battle frontier and go to the left then a little up and talk to him.
You can catch Rayquaza at Sky Pillar after you summon Rayquaza to break up Groudon and Kyogre (you don't have to wait until after you beat the Elite 4). Make sure you have the Mach Bike because you will need to go over holes in the mirage tower,
