Vanilla Conquer is a fully portable version of the first-generation C&C engine and can run both Tiberian Dawn and Red Alert on multiple platforms.
This is the Red Alert executable (formerly VanillaRA).
The focus of Vanilla Conquer is to keep the default out-of-box experience faithful to what the games were back when they were released and work as a drop-in replacement for the original executables while also providing bug fixes, compatibility and quality of life improvements.
