Namco Museum: 50th Anniversary

Japanese version

The game's Japanese release, Namco Museum Arcade Hits, has a few differences from the original US/European releases: there's a different soundtrack for the main menu, and both Pac-Mania and Galaga '88 are unlocked right from the start.

Unlockables

After beating certain high score criteria, Pac-Mania and Galaga '88 become unlockable games, finalizing the console/PC roster to sixteen titles.
