TL;DR - unless you're lucky enough to find premade sets you're going to have to do the matching by hand. However since most of us are Completists you're also going to have to edit your ROM lists manually to filter out the stuff you don't want. -------------------------------------------------------- Unfortunately I had to do what tthurman mentioned but in the end it was completely worth it. I love my setup now and it's exactly how I want it. I edited every ROM set on my Arcade Cabinet for every system(except MAME - I use the Favorites feature for that) and matched the file names for box, cart, overlay, snap, etc as I downloaded them. When I started doing this though there wasn't much on the internet set up for this kind of thing. There were a few sets I acquired that were pre-matched and I just deleted the ROMs I didn't want but these are rare. Perfect example is Atari 2600. There are a couple thousand ROMs according to Good2600 but you don't need 7 versions of Asteroids. I deleted anything that ended with [a1], [b1], [R2-D2], had a European release under a different name, etc. One shortcut I used later on was finding Hyperspin-labeled sets and matching the ROM name to the set. Someone did all the muscle work so it took less time. Side note - There's some games I just can't find a video preview for so I downloaded a YouTube video of the game (there's a lot of them) then used a program to cut a section out as a video snap. It's on my cabinet so I'm not sure exactly what that program is called right now. Some video snaps also don't show how to play the game. You can tell the snap was made by someone who didn't know the game so this method also shows a better representation of game play on your cabinet. Hope all that made sense. I'm still tired this morning.
