Play Station Portable
The PlayStation Portable is the first handheld video game console to use an optical disc format, Universal Media Disc (UMD), as its primary storage medium. Other distinguishing features of the console include its large viewing screen robust multi-media capabilities and connectivity with the PlayStation 3, other PSPs, and the Internet. The first concept images of the PlayStation Portable appeared in November 2000 at the Sony Corporate Strategy Meeting and showed a PSP with flat buttons and no analog stick, although some expressed concern over the lack of an analog joystick. These fears were allayed when the PSP was officially unveiled at the Sony press conference during E3 2004. In addition to announcing more details about the system and its accessories, Sony also released a list of 99 developer companies that had pledged support for the new handheld. Several PSP game demos, such as Konami's Metal Gear Acid and SCE Studio Liverpool's Wipeout Pure were also shown at the conference.
The PSP is sold in three main configurations that differ in which accessories are included. The basic unit package or Base Pack (called the Core Pack in North America) contains the console, a battery, and an AC adapter. The Value Pack includes everything in the Base Pack as well as a 32 MB Memory Stick Pro Duo, headphones with remote control, a carrying pouch, and a wrist strap. Sony added TV output to the PSP Slim through Firmware update 3.60. It can output in a conventional aspect ratio (4:3) or widescreen (16:9), and offers a screensaver if the PSP is inactive for a set amount of time. It is able to output games, videos, and other media. To achieve TV output on the slim model, Composite, S-Video, Component and D-Terminal cables are sold separately by Sony.
The PSP Go was revealed on May 30, 2009 The PSP Go features Bluetooth functionality, a smaller 3.8 inch screen and weighs 43% less than the original PSP. Instead of the UMD drive as found on previous models, the PSP Go has 16 GB of internal flash memory and a Memory Stick Micro port that accepts cards up to 16 GB as opposed to Memory Stick Duo. Currently, the PSP Go has a max memory of 32 GB, but the M2 memory can be increased in firmware updates. Games must be downloaded from the PlayStation Store. The sliding mechanism on the screen hides the main face buttons and the analog 'nub' when not in use. With the release of the PSP Go, all future PSP games will also receive a PlayStation Store release, whereas only a handful of games were available before
