1. Introduction The Casio SDK (Software Development Kit) allows developers to create native "Add-ins" ( .g1a for fx-9860G series, .g3a for fx-CG series) for Casio graphing calculators. These are not BASIC programs; they are compiled C/C++ binaries that run directly on the calculator's CPU, offering maximum performance and hardware access.

Build:
