Controller Ports Not working
Well I was playing my old Sega Genesis and whenever I try to use the controller I have to push down on the end plug where it goes into the port to get it to work. I know it's not the controller because I have used it on another console with no problems.

Try blowing real hard into the controller port, sometimes dust gets inside there
