I ID'ed the segments on ML102. Because of the broken corner, I couldn't turn on all of the segments, but by driving all the commons in the other 3 corners together, the ones that I couldn't turn on showed up faintly, so I could at least tell what segment (An/Bn) they are on. And I could positively ID some because I had already ID'ed the other 3 commons for that segment.

I cut out the middle of my LCD PCB so I could light the LCD from below and milled a piece of aluminum to hold the panel in place. I wound up using my laptop's screen as a polarized backlight. I didn't work too hard on the all-segments-on pic since this panel is broken and you already have a good SVG, but I need to clean everything better and use a tripod so I can get better focus with the macro lens I'm using.

I identified the remaining segments with help from ml102lcd10khc.jpg:

The game looks fine in MAME, but there are problems when you move the player on the elevator. Do you have ml102metalrom.jpg? to make sure none of the bits were 'washed' away.

Thanks, the bits look same as on the acidrom.
As a last try, I compared the visual dump against your partial electronic dump. Of the correctly dumped pages, one bit was different. I changed it and now the game works. The wrong bit looks like a "1" on both the metal and acid rom, very weird. See section at x=4900, y=4100:

The specific bit In ml102.bin:
offset $12C change $2F to $2B

That is weird! I looked at the original pics to make sure it wasn't a stitching glitch, but they look the same.
