As much as I would love to correct your grammar just to be an ass, I'll just tell you. I'm pretty sure that you need to purchase it through either e-mail, or Amazon. It's a CD ROM, and I'm pretty sure downloading it would be pirating it, aka illegal. Not to mention that you'd most likely get a virus from it. Sorry if this isn't the answer you're looking for.

Before you do, they don't mind you running the game on an emulator. So if you plan on running this game, you could probably just get dolphin.

You can get the GameCube version on emulator.
