Raptor: Call of the Shadows: 6 Open Source Clones Compared
DOS Raptor isn't a reimplementation at all -- it's a release of the game's own original DOS source code (v1.2), with the proprietary DMX audio library swapped for an open replacement (APODMX), so it needs an actual DOS-era Watcom/TASM toolchain to build rather than running as a modern native app. Raptor (the SDL2-based project) is a separate reverse-engineered codebase that runs natively on Windows, Linux, macOS, and Android, but still needs the original shareware or v1.2+ GLB asset files copied in. Raptor (JS) is a from-scratch, assets-free remake limited to just the game's first level, and it specifically requires Internet Explorer 6 to run.
