Hi everyone,
I'm new to this realm, and tried to tackle a MAME project. I had a Howler 4P PCB I wanted to use and tried that. I have a 2P config, and I wired everything up. For some reason though I cannot get JOY UP nor DOWN to work. I've tried swapping out the cables, daisychain, and even used a different joystick. Nothing seems to be helping. I have nothing plugged into either 3V3 ports. And I did unscrew and tighten to each wire coming in.
Any advice? Thank you!
