This is a list of PlayStation Portable games that support the gamesharing feature. This feature allows the player to share a portion of a game with another player, without the need of another disc.
Regions available refers to the regions of that game which have gamesharing. For example, Twisted Metal: Head On only contains gamesharing in the European version, therefore only Europe appears in its available regions column.
Gamesharing type refers to the type of gamesharing which the game has. Acceptable types for the gamesharing category are:
Regular denotes the ability to play, with two or more players, at least a portion of what would be considered the "main" game.
Mini-game denotes the ability to play mini-games with two or more players but not the "main" game.
Demo denotes a single player demo, unable to play multiplayer.
Gamesharing types are non-exclusive, meaning a game can have more than one type, separated with commas. However, they do not have to be separated by commas. Games for which the main content is composed of mini-games are listed as "Regular/mini-game". If the demo included is for another game then that game is listed in the gamesharing type column.
This incomplete list is frequently updated to include new information.
