I'm looking for existing tools and a file format spec to unpack data with filenames.

 Here file structure. It simple archive with zlib compressed data

import std.mem;

struct FileEntry{
    char path[while(std::mem::read_unsigned($, 1) != 0x0)];
    padding[1];
    u32 compressedSize;
    u32 uncompresedSize;
    u32 offset;
    // zlib compressed data
    std::mem::Bytes<compressedSize> data @ offset;
};

struct MNG {
    char magic[4];
    u32 filesCount;
    FileEntry files[filesCount];
};

MNG mng @ 0x0;

Here simple unpacker

mng_unpacker.py

Usage

python mng_unpacker.py <mng_file> [output_dir]
