Hello. I’m making my first arcade stick, and I’m having some difficulty with the Sanwa JLF. When wiring the controller, I can get the stick to respond properly. See, left and usually right work fine. But most of the time when I try up or down, It won’t read unless I’m also pushing left or right, which then reads as a diagonal. I’m using the 5 colored wires it came with, and I’m assuming the black is the ground. It’s also NOT the PCB, as the directions work fine when I wire them to buttons. I searched before I posted, but could not find a similar problem. Any advice?
