Hey peeps! I know u may be thinking what are weird codes?
Well these codes are very very strange. I meen very fery very strange. Check 'em out!

Weird Gameshark Codes:

NickName:
Note: Really works!! I tried it!


Nickname lets you go over fences and through walls.
You will be able to go behind bill's house, and around the grassy areas of Pallet! Kewl huh?
To do this enter the Gameshark code- 01a47ccf. Then go to Pewter City and buy it!!!
After u buy it, go to a fence and stand beside it. (So that Ash's head is facing the screen) Then go to items and use nickname on any pokemon. It should say that it has no effect and when it does get out of the screen and u should see something weird. You should see faces of pokemon and Ash on the screen. When it does, move the column of faces over a fence, press start, go to pokemon, cancel and go back to the main screen. Ash should be on top of the fence.
From there turn right or left which leads to the other side.
Vooala!!!

Bring memory back (Not very weird but very rare to find!!!)
Note: I have never tried this code.

If a code erases your memory and deletes your game, just enter this code- b123d7cf and it will bring back your memory.
Warning!!
Do not press "Memory Erase" on the gameshark and try this code, It will mess it up big time!

Missigno:
Enter the code 0120d8cf. Then fight in a grassy area and you'll fins him.


Missingno turn into Ditto:
To do this enter the code for Missigno. Weaken it and
catching him with a masterball. When caught the battle will still go on and when u catch it again, it will be a ditto.


Missigno turn into Rydon:
Enter the code for Missigno and then put him via pc. It will turn into a Rydon.


Weird code:
First enter the code for any pokemon, like for growlithe, and if you fight him but he isn't in his usual form, catch it and u might get another pokemon rather then Growlithe.


Invincible Pokemon:
To do this enter this code- 0100d8cf. Then fight a battle and you will fight a pokemon with no name and no picture.
Catch it and you will have a no-pic, no-named pokemon.
This pokemon will have sky attack and water gun. This code can also work with the weird code above.
Note: Put him via pc and he will then turn into a Rydon. He will have sky attack and watergun too!!!
