Examples include the second and fifth stage of Contra III: The Alien Wars, the second and fifth stage of Jim Power: The Lost Dimension in 3-D, the introduction screen of Tiny Toon Adventures: Buster Busts Loose, when a player falls off the stage in Super Mario Kart, some cinematics in Super Metroid, and in some boss battles in Super Mario World. The effect enables developers to create the impression of sprawling worlds that continue toward the horizon.Ī particular utilization technique with Mode 7 allows pixels of the background layer to be in front of sprites. This graphical method is suited to racing games, and is used extensively for the overworld sections of role-playing games such as Square's popular 1994 game Final Fantasy VI. Īll arithmetic is carried out on 16-bit signed fixed point numbers, while all offsets are limited to 13 bits. The 2D affine transformation is specified for each scanline by 6 parameters: a.

Mode 7 graphics are generated for each pixel by mapping screen coordinates to background coordinates using an affine transformation and sampling the corresponding background color.

In this way, pseudo-perspective, curved surface, and distortion effects can be achieved.

However, many games create additional effects by setting a different transformation matrix for each scanline. Two-dimensional affine transformations can produce any combination of translation, scaling, reflection, rotation, and shearing. The last one (background mode 7) has a single layer that can be scaled and rotated. The Super NES console has eight graphics modes, numbered from 0 to 7, for displaying background layers.
