[Snes] Mysterieux PCB

This invention from the people at Argonaut is a special chip that is implanted in a SNES cart, like the ones above and is called the Super FX chip. It was specialized to help the SNES to create 3D worlds made by shaded polygons and texture mapping and light source shading. The Super FX chip is a RISC type mathprocessor and a supplemental CPU to the real SNES CPU. With the FX chip in a game the SNES´s speed goes up from 3.58 Mhz to 10.5 Mhz. This is a truth with modifications though. The 'real' speed never exceded the SNES CPU's 3.58Mhz, but with the Super-FX certain difficult graphic calculations could be done faster. Developed by Argonaut Software, the Super FX chip is a supplemental RISC CPU that was included in certain game cartridges to perform functions that the main CPU could not feasibly do. The chip was primarily used to create 3D game worlds made with polygons, texture mapping and light source shading. The chip however could also be used to enhance 2D games. This chip went through three revisions, first starting out as a Chip-on-Board epoxy glob-top in the earliest Star Fox cartridges, labeled as Mario Chip-1. Within a year, the chip was given a more conventional surface-mount package and labeled as the Super FX GSU-1, which was used in various games.
