OpenClaw Runtime

A modern C++17 reimplementation of the 1997 Monolith Productions engine designed to run Captain Claw natively on Linux, Windows, and macOS.

OpenClaw replaces the aging DirectX 5 codebase with a portable SDL2-based runtime that loads original .WAP and .PID game files without modification. It eliminates legacy hardware bottlenecks (supporting 4K resolutions and 144Hz displays) while maintaining the precise physics of the original side-scroller. Developers can leverage the modular C++ architecture to extend gameplay features or port the title to new platforms while preserving the core 1990s experience.
