01xx27D1 Let you fight a Pokémon of any level.
Just replace the xx's with any number you want.
05=level 5, 0A=level 10, 0F=Level 15, 14=level 20,1E=Level 30
28=Level 40, 32=Level 50, 4B=Level 75, 63=Level 99
(If you use too high a level before you get the right badge
you may have problems controling your high level Pokémon) 

01xx1ED1 Pick your starting Pokémon with this code
Change the xx's to a number from the list.

Pick your starting Pokémon from the 3 balls at the start of the
game. Pick Pokémon from list. All balls will have the same one.
It will ask you if you want the type of pokémon that is normaly
there but you will get what you picked. After you get the
Pokémon make sure you save the game and remove the code.
Note: Some pokémon will not be playable!

01xxD8CF Pick the Pokémon you want to fight and capture anytime.
Change the xx's to a number from the list. This code will cause you to always fight the same Pokémon. Thus you will be able to capture it.
Sometimes the picture of the Pokémon will be messed up, but you
can still get it without problems later on. Use my store codes to get some MasterBalls from anystore.(Master balls cost 0 and always catch even if you don't weaken the Pokémon.)

GameGenie codes
The codes that follow let you fight any Pokémon you want. In so doing you have the chance to capture it. I recommend that you have some master balls, which  have a 100% capture rate. (If you use a master ball you won't have to fight at all). You can find my store codes that let you buy master balls at my page and  other places. E-mail me if you can't find them. Replace the xx's with the same number from the list in this faq for the best chance of getting the Pokémon you want. You can put 3 different ones in if you want. Don't expect to get the pokémon you wanted right off the bat. You will  probibly have to fight a few fights before you get the one you wanted. 

RED only codes.
xx1-91A-7FC+
xx1-93A-F7E+
xx1-9BA-5DB

BLUE only codes.
xx1-91A-7FC+
xx1-93A-F7E+
xx1-9BA-6EB

This set of codes lets you fight any pokemon you want, in the grassy areas, just north of Pallet Town. They work on the red or blue USA versions. You will not always get the pokemon you want the first time you fight. You may have to fight awhile before the one you picked comes up.
