The Dreamcast controller was the primary input device for the Sega Dreamcast console. It featured a unique design with an ergonomic shape and layout optimized for comfortable gameplay. The controller had a directional pad on the left side for movement, and a large analog stick in the center for precise control. On the right side, it had four main action buttons (labeled A, B, X, and Y), arranged in a diamond pattern, along with two triggers (L and R) on the top edge for additional input options. Additionally, it included a Start button and a smaller button for accessing the console's menu functions. The Dreamcast controller also featured a slot on the top for inserting the Visual Memory Unit (VMU), which served as a memory card and mini handheld gaming device.
