By PC you mean PC, but you connected the video output of the Wii to the... video output of the computer? Because... your TV is broken? and... just... what? This makes no sense at all.
Thank you other people for informing this guy that dolphin is the wii. Thank you extremedude2 for seeing the funny side of this (It is difficult for me as I am so exasperated by cheesynutz). Thankyou for restoring my faith that some people do, in fact, have minds.
Now don't get me wrong it IS possible to "play" the wii on the PC screen (with the proper equipment of course

), but it has NOTHING to do with dolphin

, just posting this so the OP doesn't feel like a total n00b XD
I said that, but I think he'd stopped reading what I'd written by that point.
I know. This thread is going to keep getting bumped forever with the stupidity and me losing my temper, which in turn will get me warning points for being slightly unhelpful and very rude.
