Dig Dug II is, of course, unchanged, as are all of the games in the collection-- that's kind of the point of Namco Museum (with the exception of the oddball Wii version). However, players have the option to change the method of presentation significantly. You can view the game in the normal DS orientation or turned sideways, with the screen rotated in either direction, depending on how you want to access the controller. You have the option for full-screen or the original aspect ratio in all of these configurations. There's also a softening filter that can be applied to the graphics. With so many options for displaying the games, it's slightly frustrating that there are only eight games in the collection. We want definitive DS versions of Bosconian and Metro Cross and The Legend of Valkyrie!
