Cheats #1. Get lots of items: To get almost infinite of any
item you want, first I recomend you
have beeten the game. First, go to your item list and have the
item you want alot of the sixth
item on your list. Then go to the guy who teaches you how to catch
a weedle in Viridian City
and say NO to have him teach you how to catch a Weedle. Once he's
done with the
demonstation, go fly to Cinnabar Islands and surf up and down
the right coast, half land, half
water. Then you will run into either a missingno. or a weird pokemon
thats all weird and crapy.
Run away from him. Once you've run away from him the item sixth
on your item list will be
weird, but once you use the item enough, youll have 99 of it.
You can keep doing this cheat as
much as you want.
Cheat #2. The fourth Moon stone: Go fly to Cinnabar Islands
and go into the pokemon mansion.
Once in there you will see a few pillars on each side of the main
hall. one of the pillars (I dont
remember which one exactly) on the right side you need to click
on it and you will get a moon
stone.
Cheat #3. Over lv.100 pokemon: Go to Viridian city and have
the Weedle guy demonstrate how
to catch a pokemon. Then fly to Cinnabar Islands and surf up and
down the right coast (half land,
half water) You will then eventually run into a over lv.100 pokemon.
You can use rare candies on
it until lv.255. After lv.255, it will go back down to lv.0. Once
you get into battle and kill a guy
with him, he'll go back down to lv.100
