I use No-Intro as well. And to be honest, I haven't updated my ROMs in probably 5 years. I'm still using an old/outdated version of MAME too. It just seems a tedious task to have to go through and make sure everything is up to date. For consoles, there's probably NOTHING new, just names changed as you noticed. MAME however is always being updated to provide emulation to games that were never supported, or somewhat supported. Plus, I don't believe MAME uses a naming format like No-Intro, I think they just have their own. So if I were to update ANY ROMs on my system, it would be the MAME ones. And with that, you also have to get a new version of MAME to go along with it, so that's why I haven't updated in so long. Why fix what ain't broken?
