3H Dual Arcade Joystick - Left and Up not working in Retroarch

Hi All,

I need your help to sort out a problem with Retroarch and my Arcade controller.

I recently bought a big Arcade dual controller with Pandora Box installed inside, but can work also as a normal controller via USB. When I connect the controller (3H Dual Arcade) via usb to my Macbook (new Macbook 12) and try to bind the input on Retroarch, everything is working fine apart from UP and LEFT that are not recognised. I tried the controller with Openemu and everything is working fine, so I guess it is a problem with Retroarch. Reading some other forums I found out that is a common problem using the same controller with Retropie and Raspberry. In that case, people solved the issue writing usbhid.quirks=0x16c0:0x75e1:0x040 at the end of /boot/cmdline.txt.

Do you have any idea how to solve this problem on a mac?

Thank you very much! Stefaxxx
