IGN said: "To use Game Sharing in Namco Museum, the player with the game selects the transmit function from the game's menu, while the other player selects Game Sharing on the main menu of the PSP (it's the icon with two PSPs and arrows between them indicating sharing.) Once the systems recognize each other, a short download starts where the game-less player is sent the playable selection -- after that is complete, the gamer can go ahead and play without even having a UMD game in the system."
