So I recently acquired a roller controller in pretty bad shape (it was filthy), anyway I got it all cleaned up and amazingly the optical sensors still work fine, the buttons on the other hand do not. I managed to open the buttons (you can remove the black piece by snapping it out of the top) and found that all they are is little grey rubber contact buttons (like you would find in say a SNES controller). It looked like the rubber domes had become worn/brittle with time, two of them were torn.
1. Does anyone know of a replacement for the button contacts? (the grey rubber piece)
2. Does anyone know of a complete replacement for the switch? (as in de-soldering the old switch, putting a new one in).
(I can post pictures if needed)
