Lib GCM is a low level API, and PSGL is a higher level API, but most developers preferred to use lib GCM due to higher levels of performance.This is similar to the later Play Station 4 console which also has two APIs, the low level GNM and the higher level GNMX.Apart from those appearing in the PSP console such as category icons for Photos, Music and Games, the PS3 added Users, TV and Friends to the XMB. In-game XMB features were added to the PS3 properly with firmware version 2.41 after causing early implementation problems.While XMB proved to be a successful user interface for Sony products such as PSP and PS3, the next generation Sony video game consoles such as the Play Station 4 and the Play Station Vita no longer use this user interface.Furthermore, they can use a service called Cross-Buy which allows them to buy certain games that support this feature one time, and play them in both Sony platforms.Not only that, but in the case of most such games, their saved games actually transfer back and forth between devices, allowing players to pick up from the moment they left off.) covering any Play Station Vita software title that can interact with a Play Station 3 software title.
XMB displays icons horizontally across the screen that be seen as categories.
Danish, German, English (United Kingdom), English (United States), Spanish, French, Italian, Dutch, Norwegian, Portuguese (Brazil), Portuguese (Portugal), Russian, Finnish, Polish, Swedish, Turkish, Japanese, Korean, simplified Chinese, traditional Chinese.
The process of updating is almost identical to that of the Play Station Portable, Play Station Vita, and Play Station 4.
All other later models, such as the PS3 Slim are not PS2 backwards compatible, though users can still enjoy PS3 and PSone games on them.
According to Sony, when they removed backwards compatibility from the PS3 they had already been at a point where they were three years into its lifecycle; by that time the vast majority of consumers that were purchasing the PS3 cite PS3 games as a primary reason, meaning that the PS2 compatibility was no longer necessary.
