trumank/uesave

uesave is a Rust library and CLI tool for reading and writing Unreal Engine save files (GVAS format). It provides a library for developers to work with these save files programmatically and a command-line utility for converting between binary save files and JSON format, useful for manual editing. The project is primarily aimed at game modders, developers working with Unreal Engine games, and players of games like Deep Rock Galactic who want to modify their save files.
