Would you be so kind to post your scripts here? I’ve found
$ xboxdrv \
--ui-clear \
--ui-buttonmap a=XK_a,b=XK_b,x=XK_x,y=XK_y \
--ui-buttonmap dl=XK_Left,dr=XK_Right,du=XK_Up,dd=XK_Down
and the --daemon option but can’t get them working together. By “a new config file that supports retropie (as seen on this forum” you mean method 3 from here, right?
