Still nothing. Occasionally I catch Mewtwo to test my skills and my best so far is half health and one pokeball. I hope he will reveal himself to me in his shiny form.
Oh and no luck on my other FireRed for Ponyta. Of course I could hunt for Mewtwo at the same time if one of my friends comes over. Then I might have double the chance of getting a shiny. Perhaps two, of one kind.
