Not really but my nes controller is dying or dead, idk it drops inputs and is getting unresponsive.
It's really nbd since I have a Hori dpad that works great with any console, but I like emulating on my laptop with the original console's controller. I use the Hori for handheld games and Sega.
I guess I just expect too much from an over 30 years old controller.
Its probably just dirty or corroded inside. Opening it up and cleaning the contacts with rubbing alcohol will probably fix it.
Not a bad idea.
