This is probably a hardware-related question.
I have recently bought a total of 7 (seven) different original SNES controllers from different sources, all of them being somewhat used but mostly appearing in very good condition.
All of them, with no exception, exhibit some kind of problem with the shoulder button's input registration (L/R). Mostly, the button is clearly pressed but sometimes the input does not get registered, and/or I need to apply an uncomfortable level of force for it to be registered.
The unlikelihood of this happening for every single controller I bought drove me to try some other solutions including:
- A full controller cleanup, plus alcohol treatment for the button pads
- Full replacement of all rubbers
- Homeopathic remedies
None of the above worked. So my question is: what the hell is wrong with original SNES controllers' shoulder buttons? Were they just badly designed, or am I experiencing a 100% rate of bad luck at getting a non-faulty controller?
