Level 100 code for U.S.!
NOTE: This code could cause some items in your game to be deleted. I take no responsibility for any damage caused to your game.

01282AD3
01632BD3
You should be able to go into the game and then you will have (in your items) rare candy. You've got unlimited of these, so keep on using them on your Pokémon as much as you want.

Surf without teach it to a Pokémon!
This code is a little strange so please try to follow alone

01072AD3

After entering this code, go into the game and find some water to surf on. Go into your items and there should be an item called "?????". Select this and a box should come up that says "(Name) got on ?????!". Then exit all those screens and walk into the water. You should now be surfing without using a Pokemon! This is very useful because you don't have to delete powerful abilities on a water Pokemon just so they can surf.

Mew for the US!

First, enter this code.
0115D8CF

Then go into a bush and fight a Pokémon. It should appear all screwed up. Capture it. It should be a Mew. Once you use it in battle, it should look normal. Then you can save the game (it shouldn't cause any trouble) and then you have Mew! The PokéDex even updates data! Have fun with this one.

Mew for the US!

No this is not an error, there's two ways to get Mew I think, here's the second one: To get Mew for US, start a new game (it is required that you save the game in order to do the code). Start playing through the game until you get to Vermillion city. When you get there, go to the nearest Pokémon Center. Trade a weak Pokemon with someone who has a Pokémon that has the "cut" ability. After the trade, keep playing through the game. Get 7 out of 8 badges and get the "Surf" and "Strength" HMs. Teach them to some Pokémon and go back to Cerulean city. Get the SS Anne ticket from Bill and go to the SS Anne (Vermillion City). Then, after flashing the ticket to the guard go on until you see the boat. Do not go on the boat, but instead swim on the water to the right. Swim on it until you see a platform. On that platform there is a truck. Use "Strength" to move the truck. After you move the truck, there should be a PokéBall. Inside the PokéBall is Mew! NOTE: This code does't work!

Missingno. for the US!

This code will give you a Pokémon that has no idenity at all! No picture or anything! He can't even be recorded into the PokéDex!

First, enter this code:
0120D8CF

Then go into a bush a fight a Pokémon. The screen should go dark for a couple of seconds, then a screwed up Pokémon should show up. This Pokémon is Missingno.! He doesn't have a picture and he starts off very weak. Please train with extreme care!
