PSOne theme now available on the PS4 and PS Vita

Happy 20th Anniversary, PlayStation! Thanks for twenty years of fun, Sony. After the announcement of the 20th Anniversary PS4 Edition earlier today, Sony added a theme to celebrate the occasion in the North American and European PlayStation Networks. The latest PSOne theme on the PS4 brings the look and feel of the original PlayStation console, including the original PlayStation startup music fans have loved for years. It’s time to go retro, especially if you’ve played and enjoyed PS1 games.
