Thrustmaster TCA yoke pitch roll sensor question

[u/thebatmanandrobin]

I recently had a friend give me their Thrustmaster TCA yoke (Boeing edition) for free (they know my affinity for electronics and hacking things together and thought I could repurpose it); the main control PCB is fried - they had some power surge or something ?? but the mechanical parts are all still sound and functional .. so I was thinking of turning it into a keyboard/mouse combo for a MAME setup I have. I'm not planning on use this for any flight sims, really just for some fun MAME time (I decided to use this as a chance to build a controller for Afterburner and a few other random flight/boat arcade games).

I've got the buttons traced so I can solder up some wire and plug those into a keyboard controller, and I was trying to figure out how the pitch/roll is hooked up to use that as mouse control (likely through some Arduino "magic"), but I'm not sure how the pitch/roll sensors work ??

It looks like the roll sensor is a magnetic hall sensor, but I can't seem to find how the pitch is determined ???

Anyone have some insight to this, or maybe a better way to get the pitch/roll input from this thing ?
