With there being quite a few new parts/mods for Data East Batman recently, I figured it was about time for a club. An underrated Data East game with a ton of ramps, a good skillshot, and who doesn't love Flugelheim Museum Multiball?

Replacement Joker Ramps: Freeplay40 is currently making the Joker ramp, as well as a few other locations where it is sold right now.
Color DMD has a color display out: https://shop.colordmd.com/h-led-128x16-replacement-display-for-batman-pinball-machine/
The new Pinsound is awesome: https://www.pinsound.org/en/pinballs/data-east-r3/batman/
Replacement playfields: pantherpinball has been working on getting playfields swapped.

There's quite a few Batman restoration guides here: (as well as hi-res pictures)

I'm also looking to get a Batman main ramp reproduced by one of the ramp guys here- as they were designed wrong and all of them have shattered at the same spots! Please DM me or reply if you're interested in them.

I have not.... yet. Working on rounding up all the parts to do a full restoration. As far as mods go I have a buddy working on a Batman signal that projects under/behind the cabinet. Also a potential new code in the wings! Data East code guy has it on the shortlist

I'd love to see that. I don't have a Data East batmobile but I heard that you can find diecast models that are better anyways.

That certainly isn't correct, there shouldn't be two pins hanging out there but I don't think those two pins have any wires coming out so you should be in the clear. It would be an obvious issue (not just a sound problem) if that affected anything. For sound issues I always go to the sound ROMs first, any issue in that region of the mpu?
