I use 6.1.1 and the ipac2 works out of the box. nothing special to do... however, I changed my buttons to all alpha numeric keys, and no special keys other than the standard up, down, left, right arrow keys.

The trackball working is an entirely different story.. at least in x86_64 that is.. .

As the title reads, I am running recalbox 6.1.1 x86_64, using a trackball on an Ipac-2.
It is almost impossible to find this answer, but when I start up a trackball style game, I see the trackball pointer scroll across the screen, but it does not control the game at all.

What am I missing?
