 #   ROUTINE: TRY GET UNIT MISC DATA BY UNIT ID
 #       Parameters:
 #           r4 = (ptr_UnitID) Pointer to a Unit ID (for events?)
 #               Referenced value is overwritten by the corresponding Unit Misc ID, if:
 #                   (*ptr_UnitID) != 0) and (*ptr_UnitID) < 0x100, and misc unit was found for the specified ID
 #           r5 = (ptr_State) Pointer to write state value to
 #               State =    (*ptr_UnitID) - 0xFE,   if (*ptr_UnitID) > 0x100
 #                           1,                      if (*ptr_UnitID) == 0
 #                           0,                      Otherwise
 #
 #       Returns:
 #           r2  =   0,  if (*ptr_UnitID) != 0) and (*ptr_UnitID) < 0x100, and no misc unit could be found for the specified ID
 #               =   1,  Otherwise
