Mac body: ECX (EDI) is the draw list (entry count at +0xea64, capped at 0xbb7, 0x14-byte entries, flags OR'd into +0); EDX is the cell whose +0x10 chain the new entry is appended to; [EBP+8] is stored as the entry's object and its +0x8/+0xc tile coordinates are scaled into the entry position, so it is the tile data; [EBP+0xc] is passed to the room-coordinates getter, so it is the room. Windows twin WALL2_AddRoofTile 0x004dd460 is void (pDrawList, pWall2Cell, pRoom, pTileData); the Mac stack order swaps the last two. The D2Wall2* structs do not exist in the Mac database, so those two are void * for now.
