Namco Museum Battle Collection

 Battle Collection is a collection of Namco arcade games such as Dig Dug, Pac-Man and Galaga. It was released for the PlayStation Portable in Japan on February 25, 2005 and contained eleven classic games from Namco's game history. The game was developed by Namco Tales Studio Ltd. The North American version contained an additional ten games and was released on August 23, 2005. The Europe version, which 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 as Arrangements. 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 games can also be turned onto their side and the size of the screen can be changed as well. The game also takes advantage of the game sharing feature of the PlayStation Portable and allows other players without the game to play any of the original games' 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original modes, the "waiting for start" screens (occurring after inserting a credit, but before starting the game) have been replaced by modern "console-style" options rendered in the style (font, etc) of the original games.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". It also have the option that allow players to play any level that they already play. The only games that not have the two-player mode are The Tower of Druaga and Grobda. The reason is this because the former have the different option to continue the last game on any level reached and the latter already have the stage select feature.

The Game includes Pac-Man, Ms. Pac-Man, Dig Dug, Dig Dug 2, Galaxian, Galaga, Rally-X, New Ralley-X,

Xevious, Bosconian, Mappy & other games I don't know. It also has a 3D versions of classic games which are, Pac-Man Arrangement, Dig Dug Arrangement, Galaga Arrangement & Ralley-X Arrangement.
