My conusin caught a Kygore at the first turn with a pokeball i was amazed on gameboy

type this code 82005274 0001 this is masterball gameshark code or codebreaker and go to
market and talk to the seller and they will show masterball

it's not hard catch legend pokemon with pokeball.i catch all pokemon with pokeball except
safari zone

its possible(very possible)without a master ball...trust me

First use false swipe on it then make it asleep and use a ultra ball and keep pressing a,
if it did not work keep doing it and you will catch it, it worked for me!
