Spatterlight at Mac App Store analyse

In previous versions, the library used a game's IFID to keep track of games. This meant that if several games shared the same IFID, they would also share all metadata such as title and cover image. This is no longer the case. Spatterlight now uses checksums calculated from the game file contents instead. This means that every variant of, say, Adventureland, in your collection can have its own name, cover image and release year in Spatterlight, as long as the game files are not exactly the same. Although I've worked hard to maintain backward compatibility, old autosaves and game libraries may break. Also, a ton of bugs have been fixed and no doubt a couple of new ones added.
