I'm using an Xbox360 Hori fightstick with the mame2016_libretro.dll core and 0.183 roms.
The Xbox360 controller i have does work but the fightstick doesn't register "up", it works with other cores and emulators and in the Windows joy.cpl test.
I've configured the stick manually in Retroarch but no luck, i've als tried to configure the stick in games but this also doesn't work.
I can navigate though Launchbox and retroarch with no problems.
Help:(
