Namco Museum Battle Collection is a 2005 video game compilation developed and published by Namco for the PlayStation Portable. It is the first Namco Museum title since the original PlayStation series to be developed in Japan. It includes 21 games - four of these are brand-new "arrangement" remakes of older Namco games, while the rest are emulated ports of Namco arcade games from the 1970s and 1980s. These ports include an options menu that allows the player to modify the in-game settings, such as the screen orientation and number of lives. Players can send one-level demos to a friend's console via the "Game Sharing" option in the main menu.
