Thanks hap, it's been really fun learning all this stuff
You are correct that other group segments work (btw I have grouped all segments, including single object segments). I can also get the segment that isn't lit up to show up if I change the id to another id that I know is working. It could be that I haven't located the correct pin number for the missing segment but I have tried all possible pins and still haven't found the correct one and therefore I'm starting to think that it could be an emulation problem but it can also be something as simple as bug in my script that assign segment id:s.
The posted image is from the game running in MAME. The SVG:s are looking better and I've done my best cleaning them up. This is a better rendering: [img]https://imgur.com/a/WN6ABHx[/img]
I'll keep you posted on my progress with this and if you are interested in looking into this I'll be happy to send you the files.
Update: The segment ID for the messing segment _should_ be H4A5
