3ds emulater?

I tried to get a 3ds emulater, and now I'm unsure if there really is one. I had to go through questionaires and such to get a feature for the 3ds emulater, which I don't want to have to go through.

Basically my question is, 'Is there an actual 3ds emulater, and where can I get it, without fuss. I wanna play the new professor Layton :(
