"Trace Memory: R, Gateway of Memory (known in the West as Another Code) plays very much like its DS-based predecessor. Playing as Ashley, players navigate areas solving puzzles and talking to people, attempting to gather information. The DAS (Dual Another System) returns but this time it's based off of the Nintendo DSi instead of the original DS.
One of the new features of the game is the ability to access a family tree using the DAS. Its main purpose is to provide players with background information of characters in the game. At the beginning of the game, only the Robbins' data is accessible, but as you meet new characters throughout the game, the tree will grow.
Interestingly enough, the Wii Remote is also used as a device in the game. Known as the RAS (Reboot Another System), it's used as a hacking device, allowing you to unlock doors and other objects. The player aims the Wii Remote at the lock and presses the corresponding buttons on the Wii Remote that appear on-screen."
