How do I fix my retrolink usb n64 controller's d-pad?

Question

I bought a usb controller on ebay a few months ago, and it works fine except it takes a lot of pressure to make the d-pad work. Is there a way to configure this and make it more sensitive? this makes the d-pad unplayable and I have to remap the controls to the analog for games requiring it.

Here is a picture of mine to make sure you know what one I have:

Answer 1

The only thing I can think of is that the contacts are dirty and therefore would require opening it and cleaning. Otherwise, possibly tapping the D-pad buttons repeatedly may break them in faster. I never had one, but from experience of normal N64 controllers, one of these methods should work.

Answer 3

He necesitado un joystick especial para la consola y porque el joystick que compre en los sitios web, para el ordenador, ha sido tan bueno, para la consola también lo compre de sitios web, el joystick ha merecido todo el dinero, que no ha sido mucho, funciona muy bien, tiene una buena precisión y además no se mueve en el juego, seguramente una compra excelente.
