Some guys on another forum started using the Wii emulator Dolphin a few weeks ago. Originally it's because they're American but they want to play Xenoblade.
But now they're loving it. Basically it lets you play your Wii games in HD. You still use your Wiimote (with a bluetooth USB adapter) and sometimes your PC can even read your Wii discs. If not, you'll have to download an ISO (I don't plan on using this to pirate, just to play my games in HD).
So now I'm also looking into using it, especially for when Zelda SS comes out.
Do you have any experience with it?
