Ooooooooooooooooooooooooooooooooooooooooooo. I gets yet now.

Yeah the turbo button does help, but it tends to cut down the actual playing time of a game severely. Of course this allows you to get through games much more quickly than you would playing them traditionally. For me it can be a double-edged sword, since the faster I play them on emu, when I come to play them on a console they seem extremely sluggish by comparison.
