# Guild Rebrew: C89 reconstruction of Europa 1400 binaries

> Guild Rebrew reconstructs Europa 1400: The Guild as C89 source built with the original MSVC6 toolchains. Rebrew workflows compare functions, data and layout against a server DLL and two client executables. The author reports a byte-identical server build; the two client reconstructions remain incomplete.
