Ok, I'm just gonna lay it all out there, full disclosure: I know very little about GameEx and the ROM scene in general.
Now that we have the painful disclaimer out of the way, let's get down to business. I'm trying to figure out the best route to add images, such as box art and title screens, to the previews of games. I understand that there's a particular folder set aside for each emulator that's labeled "box art" and "manuals" and so forth, but I don't understand how to populate those folders. I downloaded a screenshot zip from the main GameEx site to which I realized that the naming convention corresponded to the GoodSets nomenclature. That's all well and good, but what if you use a different set, like no-intro? Or if you're an idiot, like me, and scrubbed all the unwanted symbols and icons ([!], [h1], etc) out of names? Is there a way to scrub those out of the display name, but keep the original name intact? Also, what's up with this EmuMovies site? I just don't really understand it. How do I download things from them? I see there's a separate download service utility for EmuMovies, but do I need that to download box art databases from them?
I apologize for the myriad of questions, but I just get a bit flustered when I search for answers and I come up dry. Trust me, I'm definitely not the kind of guy to start a thread without thoroughly exhausting the "search" button. Generally, my problem comes in the form of not knowing how to funnel down my question (as you can see in the long winded paragraph above), but I try and try until I find the right combination of words. However, in this situation, I feel as though I can't find a single, straightforward answer.
So please, help a fellow game nerd out here. Throw me a bone, point me in the right direction, give me some words of wisdom, I humbly kneel at your feet.
