Anybody knowledgable on these things?
Today I picked up a spare NES Advantage, and found that it isn't 100% functional. The joystick is fine, as are the start & select buttons, but I get no in game response when pressing the A & B buttons. I would guess the rubber contact pads would be worn out, but the A button LED still lights up everytime I press the button (couldn't tell you about B, seems the LED blew out). Any guesses at what might be wrong? I hate throwing out cool controllers...
