Hello everyone ^^
I'm building a bartop mamecab, I bought 2 ultrastick 360 with 7 buttons each.
I got a question about wiring the buttons
I took the harness with the joystick of course
here's how it looks

now there's an explanation but I'm not sure if I get it.
Apprently the black cable (2) is for the ground and I have to make a chain from this one to all the button I have?
thank you for your help
here's a link at the ultimarc site
