The optional PlayStation 3 software update, version 3.15, which was released in December, is now mandatory. Sony announced today that that the firmware, which includes support for minis and a feature that enables easier transfer data from one PS3 to another, is now available to download. If you haven’t downloaded it yet, you will be prompted to do so the next time you log on.
The update creates a minis emulator on your PS3, enabling you to play these smaller games on your console. Games you have already downloaded to your PSP will be available to download on to your PS3 for free through the PlayStation Store.
The other update includes a way to transfer data from one PS3 to another. If you have purchased a new PS3, it will make the process of transferring games, save game data, and videos much easier. You will have to delete the files from your old PS3. You can also copy personal media files to your new PS3 without having to delete them on your old system.
