Add Serial port to a Action Replay 4-in-1 Cart

Hello guys, some time ago i bought a brand new Action Replay 4-in-1 Cart for Sega Saturn, but it doesn't has the serial port on the top. looking at his PCB and thinking, i believe that is possible, because on the top of the PCB there is some contacts that seens to be used to plug the port.
Unfortunely, looking at the board, i saw that is a component that connects to the port missing, if you guys could send me photos of cartridges PCBs that contain the serial port, it would help alot :thumbsup:

Thanks

PS: At now i don't have a camera, but soon i will post a photo of my PCB.
