## LUCA System

This page describes the various file formats used in the LUCA System visual novel engine made by Prototype.

A few programs which are capable of manipulating these files include LuckSystem by wetor, GARbro by morkt, GalgameReverse by YuriSizuku, and lbee-utils by G2.

### CZ Images

Images in LUCA System are stored in files which are known as CZ# files (eg. CZ1, CZ3) due to the magic bytes in the file header. These formats are proprietary, and cannot be read or manipulated by regular image viewing or editing software.
