Namco Museum Battle Collection is a collection of Namco arcade games such as Dig Dug, Pac-Man and Galaga and was developed by Namco Tales Studio Ltd.. It was released for the PlayStation Portable in Japan on February 24, 2005 and contained eleven classic games from Namco's game history. The North American version contained an additional ten games and was released on August 23, 2005. The Europe version, which was published by SCEE, was released on December 9, 2005 and was again as a Platinum and PSP Essentials hits on May 6, 2009 and April 8, 2011 respectively.
The compilation also contains four variants of several of Namco's more well-known properties, known asArrangements. These games (Pac-Man, Dig Dug, Galaga and New Rally-X) have an updated presentation and also introduce a number of new gameplay concepts to each arranged title.
The classic games have the option to rotate the screen by ninety degrees to display the original arcade resolution alongside other size options typically not found in the Namco Museum series. The game also takes advantage of thePlayStation Portable's game sharing feature to allow other players who don't have a copy of the game to play any of the classic titles' first levels.
Additionally, the games in this collection are ports, rather than true emulations, denoted by the fact that in the original modes, the "waiting for start" screens (occurring after inserting a credit, but before starting the game) have been replaced by modern "console-style" options rendered in the style (font, etc.) of the original games. The options include "1P PLAY", 2P PLAY", and "OPTIONS". Also added is the ability to select any level that the player has already played. The only games without an added level select feature are The Tower of Druaga and Grobda due to the former's option to continue the last game on any level reached and the latter already possessing a stage select feature.
