I am looking to make a pretty front end for the emulators that show the cover art/screen shots for games before they are loaded. But the problem I am currently facing is that not all roms for the same game are titled the same. For Wii ISOs, they have the game ID at the beginning of the file, so it doesn't matter what they are called on your PC, SMASH BROS BRAWL will be easily identifiable as that game and an image can be matched to it. So, is there any specific spot in each rom that is always different? If this is the game ID, it will help out a bit, but I really don't care as long as this can be used to identify games regardless of the filename.
