3rd Gen Does this actually work?

But you still bound to run into it on that route. It's pretty much the same as the shard collector's house, as in you switch 'rooms' to move the Lati. If you want two routes, though, then it's like a twenty second surf south of Mossdeep to route 128. You can just keep switching between 127 and 128 until you find the Lati.

Are you sure?

This is what it says in the FAQ:


Requirements:
-Acro Bike
-At least 1 Defeat of the Elite 4
-At least 1 Max Repel
-Something hard and heavy that you can place on a single button of your GameBoy:P

Method:
Here's what you do. After you've defeated the E4, go to any patch of grass (really, it doesn't matter where) in Hoenn and use your Max Repel. Equip your Acro Bike. Then, place your heavy object on your Game Boy in such a way that it holds down only the B button. Watch the screen and make sure that your character is bunny hopping, but is remaining in the same spot. He is? Great. Now leave your Game Boy alone for an hour or two. No, I'm not kidding. Go away for a good long while, and then come back. Don't bother watching, 'cause this method usually takes time to work. Anyway, when you come back, you (Should) have run into Latios/Latias.

Here's why it works:
Latias/Latios works in much the same way that the Legendary dogs did in G/S/C. He/She changes regions frequently, and will do so even if you stay in one region all the time. This method works on the theory that, if you wait in one region long enough, he/she'll eventually meander into it, and then you'll encounter the wily Pokemon. The Max Repel will keep other Pokemon away from you, and the bunny hopping simulates walking through the grass without wasting steps and exhausting your Max Repel.

So now you should have run into the elusive Latios/Latias. What happens next is up to you. I always used a master ball, because I hate chasing them around. But if you want to do it the hard way, just remember that once you've run into Latios/Latias, you can track him/her but everytime you go to a different location the location for Lati@s will change - look at the area page for that Pokemon in your 'Dex. It'll show the current location of him/her. Of course, this is provided you don't make him/her faint. That's it, people. Happy hunting!

I've been doing it for 2 hours now, and they haven't come...

From what i have heard this is not quite right. Lati@s will only move locations if you change areas so standing there all day waiting for it to turn up will not work. I have no evidence that i can show you that this works but you can check it by watching Lati@s move over a number of areas as you move from place to place until you feel it is sufficent proof.

What you should do instead and what i have don to get enti is pick an area with pokemon that are much lowwer than lv 30. Then place at the front of your team a pokemon under lv 30. Repel will now stop any pokemon under the level of the front pokemon showing up. In the area use a max repel and bike round until it runs out then leave the area come back and repeat the process again this will force the pokemon you are after to move area. If you wait long enought you should find it. Other wise just walk every where and wait for it to turn up.
