Hi DosBox,
I am running a raspberry pi 3 with Retropie on it.
I have DosBox and two XboxOne wired controllers in it.

I am trying to use mapper to map xbox one buttons to actual keyboard events for an old game I'd like to play (One Must Fall 2097).
Specifically, I am trying to map the D-PAD to WASD

When I use Mapper, it seems to correctly map keys for the xbox's DPAD, but when I press the DPAD buttons outside of mapper, nothing happens. Other buttons map fine and work outside of mapper, but not the DPAD.

What am I doing wrong?
Any help would be appreciated.
