Recently I bought Famicom clone from old things market for about 1 euro. Console haven’t had power supply and controls. But the problem was that this computer uses remote (Infrared) controls. Which I don’t own. So I thought maybe I can attach NES JoyPad. With logic analyzer I checked cables. And I found on internal cables is going NES JoyPad protocol data. So I attached them with NES JoyPad and now I can play games. Console comes with 20 preinstalled games.
