Looks like when the seller tested the controller last, the plug broke and stayed in the console that's also for sale. Seller probably didn't notice. Technically not lying. http://www.ebay.com/itm/TurboGrafx-16-Black-Console-TESTED-CONSOLE-ONLY-/272066712569
I was thinking that as well. You have a controller and a system, selling them separately is a dick move.
