Most of the laser blasts during the DS attack you can see them as being mostly the same, but this one looks enhanced to me. Can see the old shape, but the new rounded front edge and that it's much thicker may mean this is a 1997 enhancement.

and I think this shot proves it as the double blast has changed it's relation from above to below the X-Wing top wing.

Another 2004 cosmetic change. During this whole shot, there is a hair above the TIE on the far right. Also that white blob which shows up for a frame is 2004 gonedalagoo. Second pic can see the hair better.
