# Zeliard: DOS engine analysis and an SDL2 source port

> Reconstructs Zeliard's DOS engine and resource handling as documented C code and an SDL2 port that reads the user's original game files. Its tools extract SAR archives, decode compressed payloads and regenerate disassembly; technical notes map the boot chain, overlays and driver interfaces.
