Power Player Super Joy III - Second Player Controller Repair

The Power Player Super Joy III is a famiclone plug-and-play video game console that is built into a controller shaped like an N64 controller, and can be extended with a second controller in the shape of a Sega Genesis 3-button controller and a light gun resembling a Walther PPK pistol.

This specific device is the Player 2 controller, resembling a 3-button Sega Genesis controller, and it's meant to be plugged in to the top of the N64 look-a-like controller. It has a D-pad (which can be optionally extended using a custom joystick pole screwed in the middle), six buttons on the side, with three pairs of them labelled as A, B and C respectfully, and a Start button in the middle on the top. It has a 9-pin DB-9 female connector, although it's been customized to enlarge only five of the pins, suggesting that the cable only has five connectable wires and other four pins are not used. It can only connect to the top of the famiclone controller; it cannot be used on any other video game console like the Sega MegaDrive/Genesis or the Atari 2600.
