New replacement repair (or project) cable for Nintendo Entertainment system controllers and joysticks.
NES on one end, tinned wires on the other. Soldering required. 5 wire version which is used by most standard controllers and joysticks - not compatible with the Zapper.
Please see product images for wire color pinout
Honest review: These are cheap cables but they do work. There is really only one manufacturer producing these so options are limited. They require a little extra "oomph" at the end to seat in the controller port.
