No-Intro Screenshot Archive - These use the No-Intro naming system and they are all named via CRC. They have a renamer application that you can use to go from CRC name to No-Intro name pretty quickly.
Thanks. Any reason not to go with the videos? I imagine it slows things down a bit and takes a lot more space.
It really depends on the front end that you are going to use... Most use either video(avi) or screenshots. It doesn't really slow things down unless you are on a really old computer. They do take up a lot more space than a screenshot though. They also look much better than a simple screenshot.
I checked the site and those files have the (U)'s and (EU)'s and what nots at the end of the file. They are much easier to clean up than the ones I got, though. Now I'm wondering if my roms are poorly named. Should my roms have those denotations at the ends of the file names?
A lot of the old emumovies are named using the old No-Intro system (U), (EU) etc... Circo is working on auditing all of his sets and converting them to the new No-Intro system (USA, Euro) etc.
It doesn't sound like your roms are part of any set... It sounds like you just downloaded from various rom websites. Most of those do not use any of the naming systems available. Using one of the naming systems (No-Intro or GoodTools) allows you to quickly audit your roms against dat files and look for missing games, incorrectly named roms and other things.
