# CSVM: a Crimson Skies engine built from game-data and executable analysis

> CSVM reimplements the Crimson Skies (2000) engine in Godot and reads game data from the player's own install or disc. Its C# readers handle original formats, while format and behavior notes draw on data inspection, comparison with the game, and static analysis of crimson.exe. The build covers campaign, Instant Action and multiplayer modes.
