Mangetsu 満月

A collection of tools for reading/writing the data formats packaged in the Nintendo Switch version of the Tsukihime Remake.

Building

To build all tools, you will need at least the following

sudo apt install -y build-essential cmake zlib1g-dev libssl-dev

If you also wish to build the graphical tools, you will need some additional dependencies

sudo apt install -y libopengl-dev libglfw3-dev

To actually build the tools:

git clone git@github.com:rschlaikjer/mangetsu.git
cd mangetsu
mkdir build && cd build
cmake ..                # No UI programs
cmake -DBUILD_GUI=On .. # With UI programs
make

Tool Overview

MRG files

The MRG files operate on the mrg/hed/nam file triplets. MRG files are archive formats, and can be unzipped / zipped using the tools with the mrg_ prefix. Nam files are optional - when found, they will be used.

• mrg_info: Print the file list contained in a mrg. May optionally output in machine readable format
• mrg_extract: Unpack all files in a mrg. If a nam file is present, filenames will include the nam entry.
• mrg_pack: Construct a new mrg/hed/nam from individual files. Files will be packed in the order they are specified.
• mrg_replace: Given a base mrg/hed, create a new mrg/hed with archive entries at certain offsets in the original file replaced by new files.
• nam_read: Print the names in a nam file.

MZP files

Like MRG files, MZPs are archive formats that contain multiple sections. Unlike MRG, these files are self-describing and do not have a separate HED file.

• mzp_info: List information about existing mzp file
• mzp_compress: Combine multiple files into an mzp archive
• mzp_extract: Extract all sections from an mzp archive

MZX

MZX is a basic LZ-adjacent compression format. It is purely a compression format, with no archive capabilities.

• mzx_decompress: Decompress a MZX-compressed file
• mzx_compress: Compress a raw file using MZX compression. NOTE: This program currently does not attempt to actually do useful compression - it will generate a valid MZP output, but the output will be larger than the input file.

NXX

NXGX / NXCX files are GZIP / LZ compressed data formats with a small header. Note that NXCX support is not tested due to lack of sample files.

• nxx_decompress: Given a file in either NXGZ or NXCX format, uncompress the data to a new file.
• nxgx_compress: Given a raw file, compress in NXGZ format.

GUI Programs

If GUI support is enabled, the data_explorer file will be built. This UI allows reinterpreting a file as any of the formats above on the fly, as well as recursively extracting and displaying sub-archives of those files. It also features a hex view and other tools designed to make analysis of raw formats easier.
