Anamorphic widescreen
From Sega Retro
While the concept of 16:9 anamorphic widescreen is generally considered to have become a mainstream addition to games post-Sega Dreamcast, a number of older games support this mode, despite widescreen televisions not being readily available at the time.
In most situations, widescreen support only affects the 3D portions of a game - 2D areas such as menus are usually fixed at 4:3, and so will be streched on a widescreen display.
