The PlayStation TV launches today in North America boasting compatibility with a large number of PSP, PS Vita, and PS minis games, but users at NeoGAF point out that a last-minute compatibility update renders several major titles unplayable on Sony's new hardware.
Just prior to the system's stateside launch, Sony updated its PlayStation TV compatibility list, removing entries for notable PSP games like Twisted Metal: Head-On, Valkyria Chronicles 2, and WipeOut Pure. Several Konami-published PSone games are also no longer compatible with the PlayStation TV, including Metal Gear Solid, Silent Hill, and Suikoden.
The lack of omitted games that begin with the letters A through L suggests that Sony may be sorting out cross-platform rights issues alphabetically. While SNK-published PS minis games like Time Soldiers and Vanguard didn't make the cut, fellow SNK Arcade Classics 0 ports like Athena and Guerrilla War remain listed, hinting that further compatibility updates may be in store.
Positioned as a non-portable alternative to Sony's PS Vita system, the PlayStation TV plugs into any HDMI-equipped television and plays games and movies downloaded from the PlayStation Network. The system is available today as a $99.99 standalone package and bundled with a DualShock 3 controller and memory card for $139.99.
