It is a rare occurance. People beleive that if you use a gameshark then you wont be able to find a shiny Pokemon but that is a lie.At 1:10 today my friend Sho used the WPM and found a Pidgeotto and he caught it but realized it was a different shade of color.when he went to his PC he looked at it and it was shiny.Also with the Impossible HP Pokemon all you have to do is have max stat cheat turned on and then turn the gameshark off and switch to a Pokemon and when the battle ended it had 65495 HP in my Ruby.Thnx 4 l00kin'
