1.  CODE TO GET IFINITE ITEMS:
   First go to the old guy in Viridian City that teaches you how to catch pokemon.  Before talking to him put the item you want infinity of in the sixth position.  Then talk to him and say NO to his question and watch him teach you how to catch pokemon.  Afterwards fly to Fuchsia City and from there go to the edge of the Seafoam Islands.  Don't get on the island.  Surf up and down on the little strip where it looks like you are half on land and half on the water.  You will fight something called Missingno or "M". Run away from it and the sixth item will have a weird sign next to it.  That means you have abut 130 of it and once you are running low do it again.

2.  HOW TO CATCH MISSINGNO:
    Missingno is not a real pokemon.  Some say its a glitch. What ever it is it messes up your Pokemon Hall of Fame if you catch it so catch it at you own risk. Oh yeah also when you have it in with you (in your party) it'll mess up the fighting scene.  To learn how to catch it refer back to the first code.
3.  CATCH SAFARI ZONE POKEMON EASIER:
     Go to the Safari Zone and walk in the patch of grass the pokemon you want is in. Then fly to
Cinnibar Island and surf up and down the coast on the right side where it looks like you're on
land, but you're not. You'll come across some of the Safari Zone pokemon!  It will take a little while for the pokemon to show so be patient.
4.  CLONE A POKéMON:
   1. Make all the arrangements.
    2. Take the Pokémon you want cloned on one Game Boy, and on the
       other get a stupid, weak one that you wouldn't mind loosing
       (Pigdey, Rattata, Zubat, etc...)
    3. Now, the person with the to be cloned Pokémon, trade with the
       other.
    4. Whoever owns the to be cloned one, turn off your gameboy must time the thing very carefully.  Right before the game       says "transfer complete" the trainer that has the pokemon to be cloned must turn it off.  Then the other person can turn it off      too.  It might take a couple of tries but believe me it works.
    5. The ot. (original trainer) should have the original, and the
       other person will have the good one instead of the weak one!
    Now you both have the same exact one!

These are the only codes I have as of yet.  Remember I'm still working a lot on this site so be patient.  If you have a code then send it to me.  To send it click on the little dratini email sign.
Thanks.
