GBA-Nfo rented hosting from some company, and on that space they stored som roms. Now this was probably only private, not accessible for the public, but that doesn't make any more legal, so the hosting-company seized the domain and shut down the site. Domain is now up for offer on ebay, tho I doubt anyone really cares; if they decide to re-open the site it's probably cheaper to just make a new domain.
That said, I think it's a brilliant idea to host nfo's here, have always been annoyed about having to go to gba-nfo to read nfos. Gba-nfo also hosted ips-fixes and trainers so that could also be a thought.
