fldtools

This set of tools supports unpacking and authoring FLD data files from the game Magical School Lunar! (Sega Saturn, 1997).

Aside from the commandline tool, this project also contains a Rust crate with a few helpers to let you write your own tools for working with FLD files.

Installation

On Mac:

brew install mistydemeo/lunar/fldtools

Building manually:

Clone this repo, and then

make

Usage

fldunpack

fldunpack FILENAME.FLD

The chunks will be extracted to a set of numbered files with filenames based on the filename from which they were extracted. By default, chunks will be extracted with the file extension "chunk"; use the --extension option to choose a custom file extension. This is useful when extracting data from the MSLM.FLD file, which contains FMVs, since other apps will expect a .cpk extension from its contents.

fldpack

fldpack output.fld <input files>
