First, beat the Elite Four 12 times. Then, after you beat them the 12th time, go straight to a PokeCenter and look at the Pokemon League website. You will see a bunch of pictures of strange pokemon and other pokemon that are over level 100. Mew will be one of them. You can't use Mew or capture it, you just see it on the computer.

You need the Itemfinder to actually start this code. Then, walk around Mt. Moon and use the Itemfinder on different areas. Do that 100 times.

To capture a PokeGod, read this!!
I heard about this on another site, and I just couldn't believe that it really was true. So I tried it out for myself. Here's what I got... First, I advise you build your pokemon levels. Get them up to level 100 before you start. Stock up on supplies, like Max Potion, Full Heal, Full Restore, etc. Now, go to Indigo Plateau and defeat the Elite Four 26 times. On the 26th time, Professor Oak will say, "I'm tired of this." He will let you walk around the Pokemon Hall of Fame which leads to another city. I've heard it called Air City, but I'm not really sure about the name. In this city, people swap PokeGods. Now, if 26 times doesn't work for you, keep going at it. My friend tried the code and he had to beat the Elite Four 32 times. It's probably different in each Game Pak.
To easily build your pokemon to level 100

Here is a code to catch Missingno.

Then, FLY to Cinnabar Island and trade with any person in the Pokemon Lab. Then, SURF along the right coast of Cinnabar Island and you will run into Missingno. the "missing number" pokemon. It is number 000 and WILL NOT be recorded on Pokedex. It has strong attacks such as Water Gun and Sky Attack. Even though it has strong attacks, its defense is really low, so use a weak pokemon.
A code to capture Porygon
First, get 199 nuggets and then sell them all. You will have 999,999 dollars. Now, go to the Rocket Game Corner and talk to the guy that gives you 50 coins for 1000 dollars. Keep buying from him until you get 6400 coins. Then exchange your coins for a Porygon. This trick works for any prize you want to get.
Capture pokemon level 100+
