PlayStation Portable system software

From Wikipedia, the free encyclopedia
Jump to: navigation, search

PlayStation Portable System Software is the official, updatable firmware for the PlayStation Portable. Updates add new functionality as well as security patches to prevent homebrew applications and plugins being run on the system. Updates can be obtained in four ways:

  • Direct download to the PSP over Wi-Fi. This can be performed by choosing [Settings], [System Update] from the XMB.
  • Download to a PC, then transfer to the PSP via a USB cable or Memory Stick.
  • Included on the UMD of some games. These games may not run with earlier firmware than the version on their UMD.
  • Download from a PS3 to a PSP system via USB cable. (Japanese and American version only)

While system software updates can be used with consoles from any region, Sony recommends only downloading system software updates released for the region corresponding to the system's place of purchase. System software updates have added various features including a web browser, Adobe Flash Player 6 support, additional codecs for images, audio, and video, PlayStation 3 connectivity, as well as patches against several security exploits, vulnerabilities, and execution of homebrew programs.[1] The battery must be at least 50% charged or else the system will prevent the update code from installing. If the power supply is lost while writing to the system software, the console will no longer be able to operate unless the system is booted in service mode or sent to Sony for repair if still under warranty.

The latest version of the system software is 6.60 (as of August 10, 2011).[2] The latest reported firmware version shipping pre-installed on new PSP systems is 6.39 (as of August 27, 2011).[citation needed]
