While playing Colloseum late last night, I noticed that two of my pokemon (Quilava and Noctowl) had more of a golden flash when they came out of their pokeballs rather than the light blue one that my other pokemon had.
It's about time, too. I see thousands of pokemon since GSC, and no shinies (Except for Red Gyrados, and that doesn't count). I go in the gamecube game, and run into two of them.
Yeah- different pokeballs.
Pokeball-Blue flash
Greatball-Gold flash
(I think it's this way around).
You'd know if you had a shiny because the pokemon would be a different colour than usual.
The flashes just show which ball was used like in the GBA games.
That's what I thought, until I was told that they were shiny by 2 diffrent people. Now it looks like my first guess was right, and I'm still shiny-less
