CODES!!!!!

Use these codes at your own risk(Cheater!)

These are all glitches in the game there are no real codes known or released

Get 99 of an item: First press select on your item screen and change the item you want to multiply to the sixth space. Then go to Viridian City and talk to the man north of the city near Viridian forest who ask if you are in a hurry. Make him show you how to catch a Pokémon by saying no to his question. After his demonstration fly to Cinnabar Island and surf on the right side of the island where it is half water and half land. You will eventually see a pokémon name Missingno. Fight and knock out missingno. (its not that hard) and your sixth item should be garbled. Go into the Cinnabar Pokécenter and turn on Ash's computer. Deposit the sixth item (it should be garbled now) and deposit ninety nine of that item (you should be able to!) now withdraw from Ash's computer ninety nine of the item. There ya go! (cheater!)

How to catch over level 100 pokémon: Do the same trick as above until you get to the part where you surf for missingno. If you keep searching you will find over   level 100 pokémon (normally snorlax or golbat).
