That would mean a whole lot more gigs worth of downloads (not good). Unless the clones differ that much from the original. But most don't. There are exceptions though and the video snaps should reflect that. Most frontends will search for the original video snap if it can't find the clone snap. If they don't? Well, they should!
Anyone fixed this yet? Or have a work around? Sometimes the files will download, but most times it will not. Doesn't matter what system (Mame, Sega, Sony) I try and download. Running the latest version 2.52 on Windows 7 64-bit
