You only need the color red for BSD lol.
Haha I can only tell you that color dmd looks awesome in a Shadow, never seen a BSD with color dmd so can not compare.

You know if you buy just one, you can try the same one in both machines, and see how you like each, it's just a software update. Or just leave it in one for a while, then switch it. They're both WPC games.

If I had to choose, Shadow is a better upgrade...

Both look great, but I’d give the edge to Shadow.

That’s an lcd color dmd in the that shadow. I believe you have to use an led color dmd in bsd, due to the love never dies flashers...
I also heard you can strip the red tint off of your original display panel w/ acetone I think it was? I never ended up doing it to mi e when I had but was very tempted. Miss my bsd

Looks like LCD will work in BSD too, there's some special mounting instructions

Special Mounting Instructions

** INSTALLATION OF A COLORDMD IN BSD PINBALL MACHINES REQUIRES REMOVAL OR REPLACEMENT OF THE ORIGINAL FACTORY SPEAKER PANEL PLASTIC **

Reproduction speaker panel plastics with clear windows can be obtained from Classic Arcades website or ebay store.

LCD must be mounted alongside LOVE NEVER DIES flashers using lowest set of mounting holes on the bracket. LCD will stick above the speaker panel and obstruct opening/closing backbox door. Speaker panel must be lowered to open/close the door.

I stand corrected then. Still a good conversation to have as it may have saved some headache. The dots in BSD are far superior to the shadow. I loved the Dripping effect.
