Infinity Engine Structures Description Project

Infinity Engine Structures Description Project or IESDP is an effort to research the workings of the Bioware Infinity Engine, and act as a collective resource for those interested in such workings. This project began as the Infinity Engine File Format Hacking Project or IEFFHP and has evolved over time with many people dedicating their time in breaking down the structures of the Infinity Engine. This site showcases their work over time and how it has evolved into the current IESDP that is found at Gibberlings 3.
