To celebrate the release of Atelier Sophie: Alchemist of the Mysterious Book, Koei Tecmo launched two free themes dedicated to the game on the North American PlayStation Store.

You can find them here and here, and at the moment of this writing they're not available in Europe: I suspect they might come tomorrow, but if you cannot wait, you can always use a North American account to download and install them.

Below you can check out a few screenshots. Unfortunately they're static and lack any custom music, but they do include custom sounds.
