CIC

The CIC (Checking Integrated Circuit) is a chip designed as a method of copy protection for Nintendo cartridges, and to prevent third party companies from producing their own cartridges. There are two types of CIC chips for the SNES, the F41x, which was used for the console and several games that utilized special coprocessors, and the D41x, which was used for regular carts. The "x" part of the code was used to denote whether it was "1" NTSC or "3" PAL. Several revisions to these chips were made through the lifespan of the console.
