Sorry Troy, I should have been more precise in why I am looking for the program.
My loaders do have the ability to download the art files. However, just for example, USB Loader GX after downloading the disc art files will tell me that X number of files could not be found, (I have quite a few games and only want original, not custom disc art).
If it were the box art files it is easy to scan through the titles to see what, if any, art files are missing. The disc art is different because I cannot just scan through the titles. I would have to ‘open’ each title to see if it has the disc art or compare the ID names in the disc directory with the IDs of each disc. Either way it would be very time consuming.
That is why I am hoping there is a program that will, as I said before, look at the disc ID numbers on my HDD, compare them to the image files on the SD card and then save a file to the SD card showing what game images I am missing. This way I can do a manual search for the missing files if I want to.
If there is no program like that maybe someone can come up with one.
