# Novluno: parsing Redmoon Online data for a modern client

> Novluno investigates Redmoon Online data files and builds a Rust client that reads the original files. Its core_compat crate parses LST lists, RLE sprites, RMD data, RMM maps and RMI information files; format notes trace references between map, data, list and sprite files.
