Reproduction NES controller PCB+cable
This generic reproduction PCB and cable will fit in an original Nintendo Entertainment System game controller case, when there is no longer any other way to save your vintage hardware, except to change the PCB. At least it will still LOOK original on the outside.
You may of course choose to mount your original cable onto this reproduction PCB if you feel like it. Only basic soldering skills are needed if you choose to do this, but beware that the cable's lead colours may NOT match the ones in your original cable, so please make sure to check for continuity in order to connect the correct leads to the correct solder pads.
