  • Sometimes the LED light will just alternate between on and off. This means the game cartridge is loaded incorrectly. To fix this, simply take it out and put it back in. If this doesn't fix it, then try to clean it.
  • If you have a top-loading NES, simply put in the cartridge from the top and flip the red switch on. The grey button is the reset button.


  • Be careful when cleaning your cartridge. If it is too wet, it will break it.
