Super FX

The Super FX Chip refers to the added technology to the Graphics Support Unit (GSU) on Super Nintendo Entertainment System ROMs to support improved 2D and 3D graphics in game.

It was produced by the now defunct company Argonaut Software, and was formally known under the codename "Super Mario FX" (which contrary to some belief, does not refer to a cancelled game), and the backronym "MARIO" ("Mathematical, Argonaut, Rotation, & Input/Output").
