Also, depending on what emulator you are looking to use it for, you are going to want to make sure to use a game pad that allows Analog Input as well. And again, depending on the input, you may have to enable it. For example, in ePSXe, you have to use a gamepad plugin that shows and allows you to configure the analog joysticks, as well as press F5 to enable the analog (I ran into a lot of trouble setting it up until I figured that part out).
