Some old notes I have from around October 2008:

 

Replace XXXX with any value
81400866 XXXX - Body tilt angle (left/right)
81400864 XXXX - Body rotation (sideways)
81400862 XXXX - Body tilt angle (forwards)
81400860 XXXX - Head tilt angle (left/right)
8140085E XXXX - Head rotation (sideways)
8140085C XXXX - ? (didn't notice anything)
8140085A XXXX - Legs/entire body tilt angle (forwards)
81400858 XXXX - Body rotation (sideways, again)

XXXX is the rotation value (signed) so C000 = -90, 8000 = -180, 4000 = 90, etc.

 

The memory addresses are for Majora's Mask (U) version, they work for any area if I remember correctly.
