Old Wiimote + Motion-plus extension

[Cat Eyed Link]

I don't event know if this possible but is there a way for me to get a yaw reading from a Motion-plus extension in FreePIE. If not can anyone point me in the direction of program that can get that and pitch / roll, i pretty much want all of the motion data given to me over joystick axis from multiple wiimotes, as i am working on a Wii sports resort BR game that i need split-screen for.

pls am desperate
