Daad System

Technical reference for the DAAD (Disenador de Aventuras AD) text adventure authoring system. Use when working with DAAD interpreters, compilers, game databases, or adventure source code. Covers: DDB binary file format, all 128 condacts, system flags (0-63), object model, DSF source format, DRC compiler, MALUVA extensions, engine architecture (parser, process tables, game loop, indirection, windows, save/load). Use for: (1) implementing or modifying a DAAD interpreter, (2) writing or debugging DAAD adventures in DSF, (3) understanding DDB binary layout, (4) looking up condact behavior or system flag semantics, (5) working with DRC compiler or MALUVA extensions.

DAAD System Reference

DAAD (Disenador de Aventuras AD) is a multi-platform text adventure authoring system created by Tim Gilberts in 1988 for the Spanish company Aventuras AD. It evolved from The Quill -> PAW -> SWAN -> DAAD. Adventures are written in DSF source files, compiled to DDB binary databases by DRC, and executed by platform-specific interpreters.

Supported platforms: ZX Spectrum, Amstrad CPC, C64, MSX, MSX2, PCW, Atari ST, Amiga, PC (DOS).
