Mac body: ECX (ESI) is the unit (null-tested, unit type at +0 and class at +0x4 read, passed to the state-transform lookup); EDX (EDI) is kept as the second input for the COF component load; no [EBP+n] reads anywhere and a single plain RET (0x00069b99). Windows twin GFX_LoadMonsterModeCof 0x0046e8d0 is void (D2UnitStrc * pUnit, uint32_t nComponent); same order on Mac.
