Background
PSP game sharing allows you to wirelessly share and play games with other PSP users. One PSP with the game disc can transfer a portion of the game via an inter-PSP wireless connection, allowing other players to play a multiplayer game without additional discs of their own. The game software is transferred wirelessly and loaded onto the additional PSP's RAM. The feature is available on certain PSP titles.
Function
In order to activate game sharing, you must be in ad hoc mode, which allows you to communicate with other PSP systems wirelessly. The individual PSP systems must be set to "automatic" or to the same channel and be within close proximity (50 to 100 feet) to initiate communication. The game's menu should include a game sharing selection to begin the process--refer to individual game manual(s) for more information specific to the game.
Identification
Games that allow for game sharing have the game sharing symbol or specify that they support game sharing.
Types
Different games have different types or levels of game sharing. Regular game sharing allows 2+ players to share and play a portion of the actual game. Mini-game allows 2+ players to play mini-games that are separate from the actual game. Demo allows only one player to play a demo game.
Considerations
Game sharing is a way to play demos or multi-player games, but not a way to exchange games. Once the PSP with game sharing version of the game is turned off, the game is lost and cannot be accessed again without re initiating a game share. The download process can be very slow.
