99 Items
How to get 99 of any item. REALLY WORKS.
SEAFOAM ISLANDS Poké Cheat
How to Catch any SAFARI ZONE Pokémon in the WILD!
Master Ball Cheat: Only you will know if it works
Using any Poké Ball, press up and B at the same time as soon as you see the ball flying toward the Pokémon. I've never really gotten this to work, but players say it does, and Nintendo's Ask Dan said it works with Ultra Balls.
Get Mew (this is a false rumor)
Get all of the Pokémon and beat the game. Then go to the mansion in Celadon and go to the computer room. Go to the guy who's not on a computer and he will give you Mew! Now go trade this top selection, and get it back. Go to your Pokédex and go all the way down and you'll see Mew's Biography!
Easy Ditto Catch
Put Magikarp at top of list and let Ditto transform into a Magikarp. Then switch Pokémon--Ditto is easy to fight and catch!
Cheap Trick: Standing on top of trees
Cut down a bush stand on the spot where the bush is save and restart the game and you on top and stuck there. (Why do this?)
Better Chance Catching Safari Pokémon?

When you throw a Safari Ball, the instant you see the ball materialize, start rotating the pad from the left in a counterclockwise motion at a semi-slow speed. I have been able to catch the most difficult Pokemon in the Safari Zone multiple times. It's not 100% effective, but it is in the 80% area, and the ones that escape the ball and run away, I usually catch the next Pokemon right away. I want to be sure this is a legitimate trick, so I call on everyone to try it on your GBs in the Safari Zone.
