As you know I recently pick up my DS and there're a few questions I'm unsure. How can I return when I'm in a game, to the main screen the DS startup screen where I can pick Pictochat, or the Game. How do I Shut Down the DS? I do I just switch the Power Button off at any time? These questions might sound dumb but I just wanna make sure I'm doing the right thing. How can I adjust the screen brightness as well?
