Being from another country you might have a LED DMD in your spiderman, why are you trying to change it out? If its the old plasma types I don't know of a modification to make the lower powered ones (LED) work. If you have a plasma they tend to show shadows better as that is what was designed for that particular game.

Just bought a white Xpin from Brett this morning for our Spidy (and also a blue and red dmd cover so I can go with either blue or red on the display). As you mention, the DMD from Xmen is the newer low voltage style whereas the ones in SM are the normal / high voltage. You'll find that you won't be able to simply plug the Xmen DMD into SM as the connections aren't the same. As far as modifying it that's a good question, it would definitely have to be modified to possibly make it work, wonder if it would be worth the effort?

I'd send Brett at Xpin your question, I'm sure he'd be able to answer it. He's XPinPinball on here.

The red definitely looks nice in SM. I took the white Xpin out of our Tron and plunked it into SM with a red cover and I like it much better than the stock orange look (I also put a blue cover in SM and it looks awesome in blue).

Would be nice if you could find a way to make that red low voltage one work in SM, would look great!
