They mention using L and R for mouse clicks, but I wonder how the rest of the controls are? Stick and maybe Dpad for cursor seems obvious. But what are the B, Y, X and A buttons doing?
Looks like Select enables Fullscreen... that just confuses the heck out of me. Why wouldn't it be Fullscreen?
Dang, I don't like heavy use of the shoulder buttons as those tend to be the first to go. I do want to check it out. As far as fullscreen goes, not sure, but maybe it's two different resolution options like with Virtual Console games?
