It's not possible to do something like that.
Its literally impossible you must be out of your mind if you think it is possible to get a code that gives you shadow the hedgehog because he is from another game.
you can't unless you have game shark or other cheat codes

You cant because I tried. But you might be able to if you find a cheat engine code.
You'll need a game-shark or other cheat code device. The game itself does not have cheat codes. A game-shark (or game-genie, or whatever) replaces the games original programming with the cheat code data. when the game-shark is inserted into the console, the console will jump to the code screen before actually starting the game.
No, you are unable to get a Zapdos in Pokemon Crystal. The only possible ways are if you cheat with game shark codes or if you trade it from Pokemon red, blue, green or yellow
