October 05, 2004 - According to development sources working with the system, the Nintendo DS will feature a very intuitive start-up menu system that will give players easy touch-screen control to choose the game to play.
This menu system will enable gamers to boot a Nintendo DS or Game Boy Advance title, load up Picto-Chat, download a wireless program from specific sources, as well as other features
Also of note: each Nintendo DS game will be represented by its own graphical icon created by the developer of the game, similar to the graphic on a GameCube memory card file
As we get closer to the release of the Nintendo DS system, more details are beginning to surface on the device. One of the more interesting aspects of the Nintendo DS is its "sleep mode," an advanced version of the Game Boy Advance's own battery-saving mode where players can pause the game and power down the system without turning the system off.
On the Nintendo DS, however, it can simply be activated by closing the system.
