If anyone is trying to use the rom scraper, you won't have much luck right now. It can grab system and game info, but they haven't gotten their images back online yet. I have been toying with the idea of setting up our own database, but I would probably need to run a small kickstarter in order to be able to afford a decent host with adequate bandwidth/server space. Let me know what you guys think!
It appears to be down again. But I do get a message at the top of the screen saying: "This page (http://thegamesdb.net/) is currently offline. However, because the site uses CloudFlare's Always Onlineā¢ technology you can continue to surf a snapshot of the site. We will keep checking in the background and, as soon as the site comes back, you will automatically be served the live version"
