SNES Controller R bumper not responsive
I received a North American version of the Nintendo brand SNES controller where the right bumper does not respond. I opened it up and cleaned out all the contacts and I also can't find any sort of wire break or pin problem. I read that this may have to do with how the controller interacts with the CPU with pulse clock cycles, but other controllers I've tried don't have this issue. Is there any way to fix this problem, or am I stuck without a shoulder button to lean on?
