Recently downloaded Dolphin (Gamecub)... Can't get games to run though!

[Memnoch]

Ok i recently downloaded Dolphin, i can't seem to get Mario Kart Double Dash to run. This is the only game i've downloaded so far, so i'm thinking it could just be the game itself that doesn't run? but i doubt that because the error i get is one of the "send or don't send" errors... Any idea on this?

I'm using a Geforce 7900GS Running HAL with a 2.0 Shader

That game probably isn't playable with Dolphin yet:
