Right, I have a 2 player arcade controller. I'm trying to configure it to work with zsnes. A, B, X, Y, L, R appear to be the buttons for the zsnes. But it gives no indication what these are, nor does it indicate which are the primary buttons used. There is also something called TURBO, which I don't understand. There is also Start and Select, which as far as I am concerned are the same thing. I really need some guidance on key mapping here. Any help much appreciated.
