SuperCIC cart "key" is based on a PIC12F629 microcontroller which replaces the CIC in SNES (Super Nintendo Entertainment System, Super Famicom) game cartridges. This will effectively remove the region protection of an original game cart (not the console). SuperCIC is a project by ikari_01 where the code is free and open source. In honor of this concept we only charge a small fee for programming and packaging to keep the price low.
NOTE: This product is not required for the SuperCIC SNES kit "lock" version, but it can be used in conjunction to enable "SuperCIC pair mode" which allows region switching from the cart side of the bus.
You can find installation diagrams and code here. If you need help installing this chip you can find more info this forum topic.
