PlayStation Portable
The PlayStation Portable is a handheld game console developed and marketed by Sony Computer Entertainment. It was first released in Japan on December 12, 2004, in North America on March 24, 2005, and in PAL regions on September 1, 2005, and is the first handheld installment in the PlayStation line of consoles. As a seventh generation console, the PSP competed with the Nintendo DS.
Development of the PSP was announced during E3 2003, and the console was unveiled at a Sony press conference on May 11, 2004. The system was the most powerful portable console at the time of its introduction, and was the first viable competitor to Nintendo's handheld consoles after many challengers such as Nokia's N-Gage had failed. The PSP's advanced graphics capabilities made it a popular mobile entertainment device, which could connect to the PlayStation 2 and PlayStation 3, any computer with a USB interface, other PSP systems, and the Internet. The PSP also had a vast array of multimedia features such as video playback, audio playback, and has been considered a portable media player as well. The PSP is the only handheld console to use an optical disc format—in this case, Universal Media Disc —as its primary storage medium; both games and movies have been released on the format.
The PSP was received positively by critics, and sold over 80 million units during its ten-year lifetime. Several models of the console were released, before the PSP line was succeeded by the PlayStation Vita, released in Japan first in 2011 and worldwide a year later. The Vita has backward compatibility with PSP games that were released on the PlayStation Network through the PlayStation Store, which became the main method of purchasing PSP games after Sony shut down access to the store from the PSP on March 31, 2016. Hardware shipments of the PSP ended worldwide in 2014; production of UMDs ended when the last Japanese factory producing them closed in late 2016.
The PSP had multiple versions over its initial release, including the PSP Street and the PSP Go.
History
Sony Computer Entertainment first announced development of the PlayStation Portable at a press conference preceding E3 2003. Although samples were not presented, Sony released extensive technical details. CEO Ken Kutaragi called the device the "Walkman of the 21st century", a reference to the console's multimedia capabilities. Several gaming websites were impressed with the handheld's computing capabilities, and looked forward to its potential as a gaming platform.In the 1990s, Nintendo had dominated the handheld market since launching its Game Boy in 1989, experiencing close competition only from Sega's Game Gear and Bandai's WonderSwan and WonderSwan Color in Japan. In January 1999, Sony had released the briefly successful PocketStation in Japan as its first foray into the handheld gaming market. The SNK Neo Geo Pocket and Nokia's N-Gage also failed to cut into Nintendo's share. According to an IDC analyst in 2004, the PSP was the "first legitimate competitor to Nintendo's dominance in the handheld market".
The first concept images of the PSP appeared at a Sony corporate strategy meeting in November 2003, and featured a model with flat buttons and no analog joystick. Although some reviewers expressed concern about the lack of an analog stick, these fears were allayed when the PSP was officially unveiled at the Sony press conference during E3 2004. Sony released a list of 99 developer companies that pledged support for the new handheld. Several game demos such as Konami's Metal Gear Acid and Studio Liverpool's Wipeout Pure were also shown at the conference.
The PSP's development posed several challenges for Sony and third-party developers, with battery life being a primary concern. To address this, Sony implemented power management strategies, including restricting the CPU to two-thirds of its full speed for the first few years. The Universal Media Disc drive was another significant hurdle, as it drained the battery and had slow read speeds. Developers had to optimize their game data layout to minimize disc access and reduce power consumption. These limitations sometimes led to performance constraints and long loading times, with some titles like WWE SmackDown! vs. Raw 2006 experiencing load times of up to two minutes for certain scenes.
Launch
On October 18, 2004, Sony announced that the PSP base model would be launched in Japan on December 11 that year for ¥19,800 while the Value System would launch for ¥24,800. The launch was a success, with over 200,000 units sold on the first day of sales. Color variations were sold in bundle packs that cost around $200. On February 3, 2005, Sony announced that the PSP would be released in North America on March 24 in one configuration for an MSRP of US$249/CA$299. Some commentators expressed concern over the high price, which was almost US$20 higher than that of the Japanese model and over $100 higher than the Nintendo DS. Despite these concerns, the PSP's North American launch was a success; Sony said 500,000 units were sold in the first two days of sales, though it was also reported that this figure was below expectations.The PSP was originally intended to have a simultaneous PAL and North American launch, but on March 15, 2005, Sony announced that the PAL launch would be delayed due to high demand for the console in Japan and North America. The next month, Sony announced that the PSP would be launched in the PAL region on September 1, 2005, for €249/£179. Sony defended the high price by saying North American consumers had to pay local sales taxes and that the Value Added Tax was higher in the UK than the US. Despite the high price, the PSP's PAL launch was a success, with the console selling over 185,000 units in the UK. All stock of the PSP in the UK sold out within three hours of its launch, more than doubling the previous first-day sales record of 87,000 units set by the Nintendo DS. The system also enjoyed great success in other areas of the PAL region; over 25,000 units were pre-ordered in Australia and nearly one million units were sold across Europe in the system's first week of sales.
Hardware
The PlayStation Portable uses the common "bar" form factor. The original model measures approximately and weighs. The front of the console is dominated by the system's LCD screen, which is capable of 480 × 272 pixel display resolution with 24-bit color, outperforming the Nintendo DS. Also on the unit's front are the four iconic PlayStation face buttons ; the directional pad, the analog "nub", and several other buttons. The system also has two shoulder buttons, a USB 2.0 mini-B port on the top of the console, and a wireless LAN switch and power cable input on the bottom. The back of the PSP features a read-only Universal Media Disc drive for access to movies and games, and a reader compatible with Sony's Memory Stick PRO Duo flash cards is located on the left of the system. Other features include an IrDA-compatible infrared port and a two-pin docking connector; built-in stereo speakers and headphone port; and IEEE 802.11b Wi-Fi for access to the Internet, free online multiplayer gaming via PlayStation Network, the ability to purchase games from PlayStation Store, and data transfer.The PSP uses two 333 MHz MIPS32 R4000 R4k-based CPUs, as a main CPU and Media Engine, a GPU running at 166 MHz, and includes 32 MB main RAM, and 4 MB embedded DRAM split between the aforementioned GPU and Media Engine. The hardware was originally forced to run more slowly than it was capable of; most games ran at 222 MHz. With firmware update 3.50 on May 31, 2007, however, Sony removed this limit and allowed new games to run at 333 MHz.
The PSP is powered by an 1800 mAh battery that provides between about three and six hours of gameplay, between four and five hours of video playback, or between eight and eleven hours of audio playback.
To make the unit slimmer, the capacity of the PSP's battery was reduced from 1800 mAh to 1200 mAh in the PSP-2000 and 3000 models. The original high-capacity batteries work on the newer models, giving increased playing time, though the battery cover does not fit. The batteries take about 1.5 hours to charge and last for between four-and-a-half and seven hours depending on factors such as screen brightness settings, the use of WLAN, and volume levels. In March 2008, Sony released the Extended Life Battery Kit in Japan, which included a bulkier 2200 mAh battery with a fitting cover. In Japan, the kit was sold with a specific-colored cover matching the many PSP variations available. The North American kit released in December 2008 was supplied with two new covers; one black and one silver.
Revisions
PSP-2000
The PSP-2000, marketed in PAL countries as the "PSP Slim & Lite", is the first redesign of the PlayStation Portable. The PSP-2000 system is slimmer and lighter than the original PSP, reduced from and from. At E3 2007, Sony released information about a slimmer and lighter version for the device, which was first released in Hong Kong on August 30, 2007, in Europe on, in North America on, in South Korea on, and in Australia on. The UK release for the PSP-2000 was September 14.The serial port was modified to accommodate a new video-out feature, making it incompatible with older PSP remote controls. On the PSP-2000, games only output to external monitors and televisions in progressive scan mode. Non-game video outputs work in either progressive or interlaced mode. USB charging was introduced and the D-Pad was raised in response to complaints of poor performance, and the responsiveness of the buttons was improved.
Other changes include improved WLAN modules and micro-controller, and a thinner, brighter LCD screen. To improve the poor loading times of UMD games on the original PSP, the internal memory was doubled from 32 MB to 64 MB, part of which now acting as a cache, also improving the web browser's performance.
