"Let's say you wanted to select Downloadable Games. You'd cycle through the boxes on screen with the D-pad or left joystick and click X when the Downloadable Games box was highlighted. Once inside, the left side of the screen would have the subcategory title along with some other Sony Store ads, and the right side would break the downloadable games up even further -- Games, PSP Games, PS3 Eye, PSone Classics, Top Downloads, View Genres, and View All A-Z."
