C:\Users\goldenegg\windows>fpga-gnw-romgenerator.exe --mame-path e:\mametemp --output-path e:\output supported

Processing device gnw_ball

thread 'main' panicked at 'called Result::unwrap() on an Err value: Custom { field: "unknown variant collection, expected one of bounds, element, screen" }', src\layout.rs:139:80

Additional Context

Confirmed that the required ROMs and artwork are present. The required files can be extracted manually.

Interesting. Would you happen to be using an alternative artwork?

Could you please attach the default.lay file from your artwork zip?

Correction. It's a MAME 0.251 romset being used.

default.lay.zip

It's a standard artwork files from the 0.250 extras set.

I got an artwork set from another source and ROM generator worked. Not sure why the files from what's supposed to be the official set aren't working. I'll raise it with their team, but I'll leave it to you whether or not you want to close this ticket.

This is a really weird layout. It's completely different than all other's I've seen, and it even uses completely different "View" names (the different user-selectable ways of presenting the layers of the image) than the rest of the artwork, so my tool would be unable to accurately choose the correct view.

I should support this, but it's not going to be trivial work. It's probably not going to happen soon.
