The support for DirectB2S and DMDs is still very limited (and very experimental, but since all of VPVR is very experimental, I don't have to mention it here again).
Copy the DirectB2S file to your tables folder and rename it, so it has the same name as the table (e.g. Table Name(1998).vpx and Table Name(1998).directb2s). Lights, 7-segs and reels are not supported yet. Only the backglass image and the DMD.
As you can see in the Video, some tables just work (like Indy), but others need some rework. For the Addams I had to remove the part of the backglass with the THING text and relocate the lights. I also changed the height of the table glass to 500, because the backglass is put right on the top of the table glass.
So there is still a lot to do, but it is a start.
