Namco Museum DS is just like your old regular, standard Namco Museum. Although this time, there are some new games. It features Pac-Man, Galaxian, Dig Dug II, The Tower of Druaga, Galaga, Xevious, and Mappy. There are also two secret games; Super Xevious and an older version of Dig Dug II.
There is also a downloadable multiplier wireless game called Pac-Man V.S., previously a game on the GameCube.
The games have been slightly modified from their original versions. Each of the games originally suffered from bugs, but in this version they have been fixed. However, the player is given the option to play a bug-fixed mode of each game, or turn off the bug fixes and retain the original functionality of the game. The collection also features virtual DIP switch modes where the switches can be turned on and off using the stylus, although not nearly as many of the original switches are programmed. A diagram is listed on the top screen showing the various switch positions and functions.
There is also a music jukebox that allows the player to sample the original game tunes of the arcade games included. There are also a few unused tunes and sound effects in this mode for the various games in this collection. This is the first Namco Museum compilation title on a Nintendo handheld that allows high scores to be saved.
You can also wirelessly send any one of the arcade games to another Nintendo DS by selecting "Demo" from the main menu. The receiving Nintendo DS can then play the game via the Download Play option, and can play the full game until the system is shut off.
