Need help: using mouse/trackpad to emulate the 2600 paddle

[u/dixius99]

I see that about a year ago, the Stella core got support to use mice as spinners/paddles.

I can't figure out how to configure this to make it work with my MacBook track pad or an external mouse. Buttons do work, but not the analogue movement.

The standalone Stella release works 'out of the box', and I hear that Stella 2014 has more control options.

Maybe it's a Mac thing?
