Advice Please?

This is my first mod. And my knowledge on this is very basic. Everything I know is basically thru YouTube help videos. I am trying to connect an NES classic mini to an arcade cabinet with arcade buttons and Joystick. I have managed to get the buttons working. A,B, Start, Select are all working with the buttons. I’m having issues getting the Joystick to work. I’ve tried a few option on hooking up the joystick to the Dpad but nothing has worked. I can start a game and shoot or punch thru the A, B buttons. But I cannot move any of the players or switch thru games on the Home Screen with the joystick. So my questions are. Do I have to use the 5pin connector? Or can I wire the Dpad straight to the joystick? I have added a few pictures to show where I am at now. Thank you.
