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:  January – Silver  February – Yellow  March – Green  April – Pink  May – Dark Green  June – Purple  July – Aqua  August – Sky Blue/Blue/Dark Blue  September – Violet  October – Gold  November – Light Brown  December – Red 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. [edit] 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 2.81. Updates so far have added support for features such as:  WPA-PSK encryption for wireless communication  built-in web browser (NetFront)  ability to save audio and video from RSS channels  LocationFree Player  keyboard input mode for Web input  audio switch function  4:3 mode for Memory Stick video playback  AAC, ATRAC3plus, WAV and WMA audio playback from Memory Stick  AVC video playback from Memory Stick  GIF, BMP, PNG, and TIFF image viewing  custom wallpapers  image sharing  Chinese (simplified & traditional) fonts and encoding  higher security against various exploits and vulnerabilities Future updates are expected to add support for such features as: [20]  VoIP o voice chat  PSP EyeToy camera support o video chat  GPS receiver support  additional languages and supporting fonts  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. [21] Some of these programs encompass ISO loaders as well as emulators for older Nintendo [22] or Sega consoles. [edit] Homebrew development Main article: PlayStation Portable homebrew 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. [edit] Criticism [edit] Design problems  In March 2005 G4TV reported that several of the initial units were shipped with dead pixels and defective square buttons. They also declared that several of the features of the PlayStation Portable, such as mp3 playback, were weak offerings. Finally, they complained that the requirement of a larger memory stick to use the device's full capabilities was a large hidden cost. [23]  In March 2005 IGN cited battery life and load times as its primary criticisms of the PlayStation Portable. [24]  Report have emerged of broken Analog nub becoming common for early model PSP's [[3]] though It only seems to affect a small amount of PSP's [edit] 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."[4] 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 [5], and the other had the black woman dominant on top of the white woman. [6] Sony claims that the point was to contrast the white vs. black versions of their 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.
