Try to mix your Pokemon team around

EX; have all your Pokemon in your team a different element (fire, water, electric, grass, etc) that way you will have weakness on your side no matter who your fighting.

Another thing you should do is to make sure you level up each of you Pokemon equally. Tust me, it helps.

Fly to viridian city and talk to the man who teaches you how to catch Pokemon, and watch him catch or miss a Rattata, then fly to fuschia city and along the water that leads to the Cnnabar Islands, but keep to the very right of the screen until you get to an island.
Keep on surfing around the island until you bump into something called a M Lv0 or a Missingo Lv40. Defeat it and you will get over 100 master balls and over 100 rare candys and beats me what else but what ever you do, don't catch it. It will completly mess up your game.

P.S: my friend took about 20 minutes to find his.

P.P.S: this cheat works for blue and red users as well.[QUOTE]

Could someone please give me some help on this, been to Viridian, talked to the guy. Flew to Fuschia, went straight down, got in water, stayed right, but when I got to the bottom there was just rocks that you can't get over to get to Cinnabar island.

PLEASE HELP!!!!!!!

Okay,with this glitch you can catch any pokemon!!!First find a trainer you didnt battle.Next make sure they can see you with at least 1/2 of the screen.Stand in front of him but in a place where he don't appear in the screen.Walk to him but,when he appears,press start and fly teleport to somewhere else.Then battle someone else and go back to the place where the trainer is.When you enter in the area,the menu will appear and a Pokemon will batle u!The Pokemon depends on the special of the last Pokemon you battled.If you want,after you battle the trainer,fight a ditto and it will copy the special of you're pkmn(to battle Mew,special of 21,to battle mewtwo sp. Of 131,missingno there are a lot of sp. But I know that you can get by sp. Of 61,62 and 63).Believe,i got 3 mews with this!

I have absolutely no idea how I did this, and my Pokemon yellow was lost long ago. However there is definately a glitch.

It involved talking in the city where the water gym is and then flying to where the first gym is. Wonder around outside of the grass above the forest and enter. The music Stopped and my Pikachu stopped.

He had a blank face and would not follow me. Every few seconds my character dissapeared on screen and some japanese symbol replaced him, before going back to him. In this form I was able to walk THROUGH objects like trees and the signpost.

Unfortunately I freaked and switched off the game before exploring. I think this only occurres in the forest. (Memories of something to do with a 'bills secret garden' pop up in my head).

There IS a glitch in the game and hopefully someone can find it :)

Good luck Searching!!

To get the two rare Pokemon you need to battle players that you haven't fought before then just simply fly to lavender town go beside Pokemon tower and go directly t the left of it....
I'm not sure what Pokemon would come out but it is according to how strong the opponent that defeated....

You have 50% chance to get magmar or Mew and another 50% chance that you won't but there is a big chance if you defeat gary at the Pokemon league and go back to lavender town. There is a posibility that a magmar or Mew would appear....

PROVEN AND TESTED:
I HAVE COMPLETED MY POKEDEX..... Hehehehehehehehe byebye

All you have to do is make pikachu happy or put him on lvl 20 when you are
On cerulean city and go to that little girl that have pokemons on her house
And when she see that you pikachu is happy she will give it to you sounds easy hmm

OK. Anyone who has a Zapdos can proove this. It is true but I'm not exactly sure what it means. Do the MissingNo., or =+M'+= cheat and listen closely to it's cry. Then go look at Zapdos's stats and be amased. The cry Zapdos makes is the same. Ssuussppiicciioouuss. LOL!

OO Whoa!

All you have to do is get a simple potion and make sure Pikachu has full health,then keep giving him the potion,even though it has no effect.Do it about 6 to 20 times (that is what I reccomend) and click on Pikachu to check his status and if you see hearts above him he loves you! ^_^
