PlayStation Portable System Software is the official, updateable firmware for the PlayStation Portable. Updates add new functionality as well as security patches to prevent Homebrew (games) applications 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", "[[Network Update]]" from the [[XMB]]. (with the exception of 3.60, 3.96, 4.20, 4.21, 5.05, 5.55, 5.70, 6.36, and 6.50)
* Download to a PC, then transfer to the PSP via a [[USB]] cable or [[Memory Stick]]. (with the exception of 3.60, 3.96, 4.20, 4.21, 5.05, 5.55, 5.70, 6.36, and 6.50)
* 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 version only) (with the exception of 3.60, 3.96, 4.20, 4.21, 5.05, 5.55, 5.70, 6.36, and 6.50)


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 support, additional codecs for images, audio, and video, PlayStation 3 connectivity, as well as patches against several [[Known Exploits and Vulnerabilities|security exploits]], [[Known Exploits and Vulnerabilities|vulnerabilities]], and execution of homebrew programs. If the power supply (Battery/AC) is disconnected while updating the [[Firmware|system software]], the console will be [[Brick|bricked]]. The system will have to be booted from a different source such as a [[Pandora|battery in service mode]] with which it can be restored.

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 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. If the power supply (Battery/AC) is disconnected while updating the system software, the console will be bricked. The system will have to be booted from a different source such as a battery in service mode with which it can be restored.


The current firmware version is 6.61 and was released on January 15, 2015. It is a minor update released more than three years after the release of the previous version 6.60 in 2011.
The latest reported firmware version shipping pre-installed on new PSPs is 5.50 (confirmed by a few people who buyed a PSP-3000 Special Edition (Harry Potter Version).


To see detailed information about the security changes throughout the system software updates, see [[Security Updates]].
The current firmware version is 6.61.
