* init, func_809B1120, and func_809B11C0 OK Also migrate data to c * Match Destroy, func_809B142C, func_809B1524, func_809B15CC Start on func_809B16AC, but float register diffs :( * Everything OK but func_809B16AC and what a devil it is... * Work on func_809B16AC What an ugly function * Do some documentation * More documentation * Run formatter * Rename a few things * Address PR comments * Missed a couple angle macro opportunities * Update src/overlays/actors/ovl_En_Anubice/z_en_anubice.c Co-authored-by: mzxrules <mzxrules@gmail.com> * Anubice OK * Deleted the wrong part of the spec * A curtain was missed * Forgot a comment I changed the declaration but not the reference :I * More PR comments Co-authored-by: mzxrules <mzxrules@gmail.com>
