Yesterday I downloaded some art packs (marquees, flyers, etc) and downloaded the DATs for them to clean them up to current using ClrMamePro. It's been quite an ordeal. I'll just highlight the flyers for example. I downloaded the 4 flyer packs from arcadeflyers.net and downloaded the DAT file from clrmame.com, so as to have the latest version of both. I put the 4 flyer zip files into one folder, and loaded the DAT into CMP. I then set the ROM-Path to the folder in which the 4 zips are. I then went to scan, thinking that CMP would be able to check the individual files inside the zip files. It reported missing sets 1 of 1, missing ROMs 0 of 2578. I thought that was rather odd, so on a hunch I removed one of the zip files from the folder and scanned again. Much to my surprise, it still said missing ROMs 0 of 2578. At that point I knew something was wrong. I searched the forum here and discovered that apparently according to the two "scanmodes", either all the files would have to be in a single zip file, or all the files have to be unzipped into a single folder. So I tried unzipping them all into that same folder, and moved the original zip files out, and scanned again. Now CMP reports missing sets 1 of 1, missing ROMs 2578 of 2578, and unneeded files 2578 of 2578. I read some more on the forums, and saw that the folder name should be the same as the set name. So I renamed the folder "flyers", and scanned again; same result.

I know there's something I'm doing wrong, but I'm just not sure what. Any assistance would be appreciated. Thank you!
