This is both docked and undocked, in OG and Turbo. I'm not going to say it's unplayable or anything, but it sure as hell isn't a pleasant experience. There are better ways to play the 6 NES games, like on 3DS Virtual Console. The lag is at least 5 or 6 frames. It feels sluggish and unresponsive. You can literally hear the delay between a button press and a buster shot going off. MMLC2 is fine, it's just the first one.
