Hello friends. I have a PlayStation 1 that I received as a gift when I was 6 or 7 years old. It's been sitting in a corner for 25 years. I bought a new analog stick and Oddworld Abe's Exodus to use it. The console and the game work. The game's splash screen appears, but I can't use the stick to play commands. The joystick's light is on. Could there be a problem with the console? Does anyone have any suggestions?
