You are right. Looking at the ZXDB, it is a very sophisticated but complex setup. If you are willing to get help from AI that could cut down the time substantially or create a temporary DB + website in Lovable?

I wouldn't want to spread the data across different websites, because it would only make things more confusing... Ideally, I'd update the ZXDB. It would be even better to update the information on the official website specnext.com. But honestly, I don't even know when I'll get around to it, because I'm still finding games and utilities. And this is just a collection of data and files, I haven't even started studying them yet...
