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 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. Some regions have modified versions of this pack that include different accessories. Many limited edition versions of the PSP that include various accessories, games, or movies have also been released.
