It works on a US system but the features are limited. The remote is designed to work with Japanese SCPH-18000 and newer models with DVD Driver 2.0, the latest US DVD Driver is 1.30U. You\'ll be able to use the standard buttons on the remote such as R1/R2/R3/L1.. X, circle, square, triangle, basically all the buttons you find on the Dual Shock 2. What you won\'t be able to use are the nifty slow motion buttons and various menu shortcuts such as "audio setup", "chapter select", "angle select".
