The cockpit is divided into three rows. The top and bottom row using all 16 colors for the cockpit image.
The middle part only uses four colors while the remaining 12 colors are reserved for the 3D content.
The upper 2/3 of the cockpit can be removed to conserve oxygene. Since this is a memory snapshot, it shows both parts separately. In game the top part snaps over the lower part, filling the gap between them.
