The PlayStation Portable system software is the official firmware for the PlayStation Portable. It uses the XrossMediaBar (XMB) as its user interface, similar to the PlayStation 3 console. Updates add new functionality as well as security patches to prevent homebrew applications and plugins from being executed 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. See also List of PlayStation Portable system software compatibilities.
• 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. The battery must be at least 50% charged or else the system will prevent the update 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 current version of the software, 6.61, was made available 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.

Technology

Graphical shell

The PlayStation Portable uses the XrossMediaBar (XMB) as its graphical user interface, which is also used in the PlayStation 3 (PS3) console, a variety of Sony BRAVIA HDTVs, Blu-ray disc players and many more Sony products. XMB displays icons horizontally across the screen that be seen as categories. Users can navigate through them using the left and right buttons of the D-pad, which move the icons forward or back across the screen, highlighting just one at a time, as opposed to using any kind of pointer to select an option. When one category is selected, there are usually more specific options then available to select that are spread vertically above and below the selected icon. Users may navigate among these options by using the up and down buttons of the D-pad.

The basic features offered by XMB implementations varies based on device and software version. On the PSP console, the XMB had top level icons for Photos, Music, Videos, Games, Networking (which allows the use of the web browser), Settings and Extras. Also, XMB offers a degree of multitasking. With the PSP, using the Home button while playing music would allow users to browse photos without stopping the music. While XMB proved to be a successful user interface for Sony products such as PSP and PS3, the next generation Sony video game consoles such as the PlayStation 4 and the PlayStation Vita no longer use this user interface. For example, the XMB is replaced by the LiveArea interface on the PS Vita.

Web browser

Web browser on a PSP-1000

The PlayStation Portable comes with a web browser for browsing the Internet. The web browser is a version of the NetFront browser made by Access Co. Ltd. and was released for free with the 2.00 system software update. The browser supports most common web technologies, such as HTTP cookies, forms, CSS, as well as basic JavaScript capabilities.

The version 2.50 upgrade added Unicode (UTF-8) character encoding and Auto-Select as options in the browser's encoding menu, and also introduced the saving of input history for online forms.

Version 2.70 of the PSP's system software introduced basic Flash capabilities to the browser. However, the player runs Flash version 6, five iterations behind the current desktop version 11, making some websites difficult to view.

There are three different rendering modes: "Normal", "Just-Fit", and "Smart-Fit". "Normal" will display the page with no changes, "Just-Fit" will attempt to shrink some elements to make the whole page fit on the screen and preserve layout and "Smart-Fit" will display content in the order it appears in the HTML, and with no size adjustments; instead it will drop an element down below the preceding element if it starts to go off the screen.

The browser also has limited tabbed browsing, with a maximum of three tabs. When a website tries to open a link in a new window, the browser opens it in a new tab.

Parents can limit content by enabling Browser Start Up Control which blocks all access to the web browser and creating a 4-digit PIN under [Settings] in [Security]. Additionally, the browser can be configured to run under a proxy server and can be protected by the security PIN to enable the use of web filtering or monitoring software through a network. Recently, TrendMicro for PSP was added as a feature that can be enabled via a subscription to filter or monitor content on the PSP.

The PSP browser is slower compared to modern browsers and often runs out of memory due to limitations put in place by Sony. Alternatively, Homebrew has allowed a custom version of the browser to be released that utilizes all 32/64 MB of the PSP's RAM, which allows the browser to load pages faster and have more memory for larger pages. Opera Mini can also be used on PSP through PSPKVM, a homebrew application which is a Sun Java Virtual Machine. It was claimed to provide much faster loading times than the default browser and provides better web page compatibility.

Other features

Like many other video game consoles, the PlayStation Portable is capable of photo, audio, and video playback in a variety of formats. However, unlike Sony's home consoles such as the PlayStation 3 and the PlayStation 4, it is not possible to play Blu-ray or DVD movies on the PlayStation Portable directly since it lacks of a standard Blu-ray or DVD drive. While it does have a UMD drive and there exist UMD movies, the UMD format never saw implementation on any device other than the PlayStation Portable and as a result the market is very limited compared to those for other optical media formats. There have been no more movies released on UMD since 2011, and the final Harry Potter movie was one of the final releases on the format.

The PlayStation Portable also supports a feature known as Remote Play, which allows the PSP to access many features of a PlayStation 3 console from a remote location using the PS3's WLAN capabilities, a home network, or the Internet. However, unlike the later Remote Play feature between the PlayStation Vita and the PlayStation 4, the Remote Play capabilities between the PSP and the PS3 are much more limited. Although most of the PS3's capabilities related to its main user interface are accessible with Remote Play, playback of DVDs, Blu-ray Discs, PlayStation 2 games, most PlayStation 3 games, and copy-protected files stored on the PS3's hard drive are not supported. Actual Remote Play between the PSP and the PS3 games are only supported by a "select" very few PS3 titles.

Furthermore, PSP-2000, PSP-3000 and PSP-N1000 can use the Skype VoIP service starting with system software version 3.90. The service allows Skype calls to be made over Wi-Fi and on the PSP Go over the Bluetooth Modem feature. It is not possible to use the VoIP service on the original PSP-1000 console due to hardware limitations. There also existed other services for the PSP such as the Room for PlayStation Portable, similar to the PlayStation 3's online community-based service known as PlayStation Home.

Custom firmware

Homebrew development was very popular during the time of the PlayStation Portable. Besides the official firmware (OFW) made by Sony, custom firmware (also written as Custom Firmware, or simply CFW) is also commonly seen in the PlayStation Portable handheld consoles. Custom Firmware allows the running of unsigned code such as homebrew applications and UMD backups, emulators for other consoles as well as PSone games when the disc images are converted into PSP format, unlike official system software which usually only allow signed or retailed copies of software to run. Famous Custom Firmware include the M33 Custom Firmware by Dark_AleX as well as those made by others such as the Custom Firmware 5.50GEN series, Minimum Edition (ME/LME) CFW and the PRO CFW. Since from the early days hackers working on the PSP discovered exploits in system software 1.00 and 1.50 that allowed them to run unsigned code on the PSP, many PSP-1000 users had downgraded their consoles to these versions in order to install a Custom Firmware corresponding to a higher version of the system software. Later exploits were discovered in some more recent versions of the system software too allowing the installation of homebrew content. Sony had put significant effort into blocking Custom Firmware and other third party devices and content from their PSP consoles, but their effort was not quite successful for the PSP. In July 2007 Dark_AleX officially stopped his work on the PSP, citing perceived problems with Sony as one of the reasons for his departure, but other Custom Firmware continue to be developed or updated. However, this would be very different for its successor, the PlayStation Vita. Unlike the PSP, there is currently no native CFW for the PS Vita, as the modding scene of the PS Vita is almost non-existent. There only exists eCFW for the PS Vita, meaning Custom Firmware for PSP running in the PSP emulator of the PS Vita, but the features of eCFW are expected to be much more limited than a real CFW for the PS Vita.

Version	Date Released	Description
2.82	October 26, 2006	System Changes Revisions to strengthen security have been added.
2.81	September 7, 2006	System Changes Support for memory sticks with a capacity greater than 4GB. Revisions to strengthen security have been added. Patched a libtiff exploit (2nd of 3).

2.71	May 30, 2006	Network Changes Support to download Game Demos from the Internet Browser.

2.60	November 29, 2005	Network Changes Support for Audio RSS feeds. System Changes Revisions to strengthen security have been added. First attempt at patching the 2.00-2.50 GTA exploit. Security update was later found not to work correctly in every version through 3.03 (Grand Theft Auto: Liberty City Stories exploit). An overclock bug (or limit?) was introduced with this update preventing the CPU from going above 222mHz while WiFi is activated. This is a predictable and reproductive behavior where if the CPU is overclocked (such as 266-333) before activating wifi, the behavior is nullified until the next complete shutdown. This is still present in the latest firmware. This could have been an attempted limit by Sony to anticipate the lower voltage of the battery in the PSP-2000 to prevent drawing too much power at once.
