Games
This is a list of games that are available for the Playstation Portable, in which are both released and/or in development. To date, the top-selling game is Grand Theft Auto: Liberty City Stories.
top
Controls
Despite its movie and music playback capabilities, the PlayStation Portable has primarily gaming-oriented controls (as opposed to the controls typical to television remotes or MP3 players): two shoulder buttons, the PlayStation face buttons (triangle, circle, cross, square), start and select buttons, a digital 4-directional pad, and an analog stick. There is also a row of secondary controls along the underside of the screen, for controlling volume, music settings (either switching the audio off and on in games or selecting different equalizer presets), screen brightness, and accessing the system's main menu.
The PlayStation Portable's analog stick, often referred to as the analog "nub", is a circular disc which slides rather than tilts. The PlayStation Portable's analog stick can also be easily removed and replaced with a third party stick.

Multimedia and codecs
|
Because Sony's software is not the only toolset for getting music or movies onto a PlayStation Portable, a cottage industry has grown around offering useful tools for converting and copying files for use on the PlayStation Portable. Some popular alternatives include Media Boss,• PlayStation Portable Movie Creator,• PlayStation Portable Video Express,• Xcopy9,• PSPWare•, iPlayStation Portable,•PlayStation Portable Media Studio,• PlayStation Portable Video 9,• 3GP Converter, PlayStation Portable Multimedia Extender• - all simplify the task of converting and transferring files to and from the PlayStation Portable's Memory Stick. Additionally, some FOSS programs, such as FFmpeg can be used to convert video into a properly sized and formatted PlayStation Portable video file. Using these tools, nearly any digital video file (including movie files ripped from DVDs or digital video recorders like the TiVo) can be played on a PlayStation Portable, after conversion to AVC.

Video capture hardware
Alongside the numerous software applications devoted to PlayStation Portable video, there have been hardware devices specifically designed for various PlayStation Portable-centric applications. For example, the Neuros MPEG-4 Video Recorder 2 is an MPEG-4 video recorder specifically designed to put analog video, from standard A/V connections, into a format recognizable by the PlayStation Portable. Rather than simply convert the video file and leave it to the user to transfer the file properly, it records directly into the PlayStation Portable's native file and directory structure, on the memory stick itself. Another example of PlayStation Portable-dedicated hardware units are the various adapters designed perform a reverse process - display the PlayStation Portable's output on a television. These devices have various modes of operation, with some simply using the method of pointing a video camera at the screen. •
Video file sizes largely depend on the audio and video bit rates. With reasonable settings (a resolution of 320×240, a video bit rate of 500 Kilobits per second, and an audio sampling rate of 22050 kHz) a 22 minute movie file is roughly 55 megabytes. (This is enough for a 30 minute television episode with the commercials removed) This means that a 512 MB Memory Stick can hold approximately nine of these files. A hundred-minute feature film can fit on a 256 MB Memory Stick.
Many movie files, both free-to-distribute and pirated, have been encoded for the PlayStation Portable and are available on the internet. Game and movie trailers, in particular, are increasingly available, even from the studio's official site.

Camera and GPS
A camera and GPS attachment were first announced for the PSP in March 2006. More details are set to be released during Tokyo Game Show 2006.
The GPS receiver will feature support for GPS-enabled games such as a projected re-release or update of Hot Shot Golf, as well in Metal Gear Solid: Portable Ops. The GPS is set to be priced around ¥6,000, appx. $54 USD.
The “Chotto Shot” (Quick Shot) camera add-on will support a new video and VoIP chat service, as well as photo taking. Both the camera and service are slated for release in Japan in December 2006 for around ¥5,000, appx. $44 USD.*

Wireless networking
The PlayStation Portable can connect to a wireless network through Wi-Fi IEEE 802.11b which allows it to surf the web or connect to other PlayStation Portable units for multiplayer gaming world-wide. Use of wireless network features increases the power consumption and lowers the battery life of the system by 30%.
Firmware 2.00 was released on July 27, 2005 for Japanese PlayStation Portables, and August 24, 2005 for North American PlayStation Portables. The update included a web browser and support for connecting to networks with WPA and WEP encryption.
top
Gamesharing
Some titles for the PlayStation Portable support a feature dubbed "gamesharing", which facilitates a limited set of multiplayer features between two PlayStation Portables with only one copy of the game UMD. A reduced version of the game being shared is transferred to the PlayStation Portable without a UMD via the PlayStation Portable's Wi-Fi connection, whereupon it is loaded into RAM and runs.
Such "gameshare versions" of titles usually have their feature set reduced because of technical limitations. This is mainly due to transfer times since data for the game must be transferred to the second PlayStation Portable wirelessly, at a rate of 11 megabits per second. Also, since the game data is stored in the PlayStation Portable's RAM, there is a storage limit of 32 MB.
top
Ad-hoc networks
Ad-hoc wireless networking allows for up to 16 PlayStation Portables within range to communicate directly to each other (typically for multiplayer gaming). One unit acts as the host for a game, which is available to other PlayStation Portable units within that system's range, and appears in a list when the client PlayStation Portable searches for available hosts. Hosting a game in this manner increases power consumption and reduces battery life by as much as thirty-five percent, depending on the complexity of data transfer. With the update of 2.00 or higher the PlayStation Portable can use the Ad-Hoc technology to digitally send pictures from one PlayStation Portable to another by use of the "send" and "receive" functions that appear in the "PHOTO" menu.
top
Infrastructure networks
The PlayStation Portable's main menu allows the user to configure the system for use across the internet or an intranet via a wireless connection, known as infrastructure mode. The PlayStation Portable's menu can recognize protected and non-protected wireless networks within its range.
Use of infrastructure networks in PlayStation Portable software began with a small number of titles at the U.S. launch, supporting online play. South Korean PlayStation Portables have shipped with software providing web browsing and multimedia streaming features, but only through company-owned Wi-Fi hotspots, and with a monthly fee.•
Sony's Location-Free Player allows users to watch television on their PlayStation Portable over the internet. Through the Location-Free Player, users can view and control their TV from anywhere they have access to a wireless network.

Infrared
The PlayStation Portable features an IrDA port located on the top left of the device; however this is not currently used by any games.

Technical specifications
The PlayStation Portable was designed by Shin'ichi Ogasawara 小笠原伸一 for the Sony Computer Entertainment company. Early models were made in Japan but in order to cut costs, Sony has farmed out PlayStation Portable production to non Japanese manufacturers, mainly in China.
The unit measures 170 mm (6.7 in) in length, 74 mm (2.9 in) in width, and 23 mm (0.9 in) in depth, and has a mass of 280 grams (a weight of 0.62 lbs) including the battery. The TFT LCD screen measures 110 mm (4.3 in) diagonal with a 16:9 ratio and sports a 480×272 pixel resolution capable of 16.77 million colors.
The PlayStation Portable's main microprocessor is a multifunction device that includes a MIPS R4000-based CPU, hardware for multimedia decoding (such as H.264), as well as a vector unit dubbed "Virtual Mobile Engine". The MIPS CPU core is globally clocked between 1 and 333 MHz. During the 2005 GDC, Sony revealed that it had capped the PlayStation Portable's CPU clock at 222 MHz in software. Its reasons for doing so are unknown, but are the subject of some speculation. Various homebrew tools enable users to operate at 333 MHz, generally leading to a higher framerate at the expense of battery life.
The system has 32 MiB main RAM and 4 MiB embedded DRAM. There is no memory management unit for the CPU. No evidence of a TLB has been found to date. The Coprocessor 0 that normally manages the TLB-based MMU seems to be a custom effort by Sony and has no integrated memory.
The 166 MHz graphics chip has 2 MiB embedded memory and through its 512 bit interface provides hardware polygon and NURBS rendering, hardware directional lighting, clipping, environment projection and texture mapping, texture compression and tessellation, fogging, alpha blending, depth and stencil tests, vertex blending for morphing effects, and dithering, all in 16 or 32 bit colour, along with handling image output. Specifications state that the PlayStation Portable is capable of rendering 33 million flat-shaded polygons per second, with a 664 million pixel per second fill rate.•
Unlike Sony's PlayStation 2 console, the GPU (PS2 Vector Unit equivalent) is not programmable, meaning that many effects that the PS2 can resolve in hardware must be implemented in software on the PlayStation Portable. Nonetheless, the implementation of a GPU in the PlayStation Portable is still a significant technological advance, in that it implements robust hardware-rendering for 3D graphics in the handheld market. The PlayStation Portable was preceded in this regard by the Tapwave Zodiac and the Nintendo DS.

Interface
The PlayStation Portable's main menu interface is the "Cross Media Bar" (XMB) used by recent Sony TVs, the PSX (DVR) hardware, and the upcoming PS3. It consists of a horizontal sequence of icons (Settings, Photo, Music, Video, Games, and Network which, when highlighted, show a vertical sequence of sub-icons (for example, selecting Games allows the memory stick or a UMD to be selected).
The main menu system allows the user to, amongst other things, adjust settings such as date, time, and the PlayStation Portable's nickname for wireless networking, play video or audio files from the memory stick, load games or movie UMDs, check on estimated battery life, and set the PlayStation Portable into a "link mode" which makes the inserted memory stick available to a PC via USB. The XMB may be accessed at any time in a game by pressing the "Home" button on the console.
The PlayStation Portable's default background color is defaulted to change depending on the current month of the year, as follows:
Firmware 2.00 and greater allows the user to manually pick a color theme (though one can still set it to change color by month) or specify a background image from any stored photo on the PlayStation Portable memory stick. A variety of homebrew programs allow users of older firmwares to change the PlayStation Portable's background image but only of a limited dimension.
User skins for the UI may also be made available through online downloads or on UMDs as extras.

Firmware
Each PlayStation Portable runs a particular version of the PSP firmware, which comprises the device's operating system and additional core functionality. Firmware updates can be obtained in three ways:
Direct download to the PSP over Wi-Fi. This can be performed by choosing "Settings" "Network 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.
While firmware updates can be used with PlayStation Portables from any region, Sony recommends only downloading firmware updates released for the corresponding region. The current firmware version is 2.82 .
Updates so far have added support for features such as:
WPA-PSK encryption for wireless communication
Macromedia Flash Player 6 support added with firmware 2.70
Ability to save audio and video from RSS channels.
Keyboard input mode for Web input
4:3 mode for Memory Stick video playback
To play AAC files, Firmware 2.70 was required. AAC files ending in .3gp requires 2.82.
AVC video playback from Memory Stick
Chinese (simplified & traditional) fonts and encoding
Higher security against various exploits and vulnerabilities
Future updates are expected to add support for such features as:•
Additional languages and supporting fonts
An official PlayStation emulator
One of the possible reasons for an increase in firmware updates is to prevent homebrew programs for the PlayStation Portable from being executed.• These programs are often harmless home-made games and applications which might add new functionality to the PSP, although they include ISO loaders, which allow users to run pirated PSP games, and emulators for older systems, such as Nintendo• or Sega consoles.
top
Homebrew development
In May 2005, it was found that PlayStation Portables using the 1.00 version of the firmware (meaning original, first launch Japanese-only PlayStation Portables) could execute unsigned code. What this meant in practice was that these PlayStation Portables could run homebrew software, as the mechanism for checking to make sure that software has been approved by Sony had not yet been activated. Later exploits have allowed for PlayStation Portables using later versions of the firmware to run homebrew applications, and development of both new exploits to bypass restrictions and new restrictions to limit unauthorized programs is ongoing.

Design problems
In March 2005, the cable TV program G4TV reported that several of the initial units were shipped with dead pixels and defective square buttons. It also declared that several of the features of the PlayStation Portable, such as mp3 playback, were weak offerings. Finally, it complained that the requirement of a larger memory stick to use the device's full capabilities was a large hidden cost.•
In March 2005, the Internet gaming site IGN cited battery life and load times as its primary criticisms of the PlayStation Portable.•

Controversial Ad campaign
On July 5, 2006, news spread out that an ad released in the Netherlands showed a white woman holding a black woman by the jaw, saying "PlayStation Portable White is coming."* Some found this to be racist because of the physical violence and portrayal of a white woman subjugating a black woman in the ad, reminiscent of slavery. There were two other variants of this ad, one had the two women facing each other on equal footing in fighting stances *, and the other had the black woman dominant on top of the white woman. * Sony claims that the point was to contrast the white vs. black versions of its machine available for sale. Critics claim that these alternative advertisements were created for plausible deniability, and that Sony was counting on the free publicity the "racism" charges would stir up. Sony had stated that these ads will not be released in the rest of Europe nor North America. Sony has recently announced that the controversial ads that have so far only been released in the Netherlands will now be pulled from that country. •
