@mitu Thank you very much! It works!

It depends how many roms you have and how many of them are part of the current mame set 0.201+202 if Progetto or scraping will be better. But a good option nonetheless.

@trailjacker I personally don't know a lot about scrapers. I usually use sselph's scraper and then manually add videos on my own, though I'm using an old version of the scraper.

Sorry I'm not more helpful here - maybe a separate thread with that particular question may help?
