Namco Museum - Namco Museum: 50th Anniversary

This title refers to Namco's 50 years as a company which originally manufactured toys in 1955. It was the second "Namco Museum" compilation to be released on the PlayStation 2, Xbox, and the Nintendo GameCube (The scaled down version on Game Boy Advance was also the second "Namco Museum" compilation for the GBA). It was also released on the PC.

The versions on PS2, Xbox, NGC, and PC include sixteen games:

• Pac-Man (1980)
• Ms. Pac-Man (1981)
• Galaga (1981)
• Galaxian (1979)
• Dig Dug (1982)
• Pole Position (1982)
• Pole Position II (1983)
• Rolling Thunder (1986)
• Rally-X (1980)
• Bosconian (1981)
• Dragon Spirit (1987)
• Sky Kid (1985)
• Xevious (1982)
• Mappy (1983)
• Pac-Mania (1987) - locked initially
• Galaga '88 (1987) - locked initially

Both Pac-Mania and Galaga '88 are locked initially and require 15000 in Pac-Man, 20000 Ms. Pac-Man and then 40000 in Galaga to unlock.

This is the first edition of Namco Museum to feature true arcade game emulation using the original game ROMs. Also, the Nintendo GameCube version allows the player to insert a limited number of credits, about 5 or 6, by repeatedly pressing the Z button when the game first starts, but then players can only exit to the main menu during game play. The PS2, Xbox, and PC versions allow the player to exit a game at any time, but skips being able to add credits. For Dragon Spirit, Pac-Mania, and Galaga '88, the continue features from the original arcade versions have only been retained in the PC version of the collection.

This collection (except for the scaled down GBA version) also features five songs from the 1980s:

• Come on Eileen by Dexys Midnight Runners
• Working for the Weekend by Loverboy
• She Drives Me Crazy by Fine Young Cannibals
• Talking in Your Sleep by The Romantics
• Joystick by Dazz Band

These songs are played in the game selection menu. As in the previous collection, there is no actual "museum" content.

The PC version was negatively received because it contains StarForce protection, and it does not run on Windows 7.

In Japan, this was released under the title Namco Museum: Arcade Hits for PlayStation 2 only with Pac-Mania and Galaga '88 unlocked right from the start.

The scaled down version on Game Boy Advance includes five games:

• Pac-Man (1980)
• Ms. Pac-Man (1981)
• Rally-X (1980)
• Galaga (1981)
• Dig Dug (1982)

Like the original Namco Museum for the Game Boy Advance, this version does not save high scores.
