nod-rs

Library for traversing & reading GameCube and Wii disc images.

Originally based on the C++ library nod, but does not currently support authoring.

Currently supported file formats:

• ISO (GCM)
• WIA / RVZ
• WBFS (+ NKit 2 lossless)
• CISO (+ NKit 2 lossless)
• NFS (Wii U VC)

CLI tool

This crate includes a command-line tool called nodtool.

info

Displays information about a disc image.

nodtool info /path/to/game.iso

extract

Extracts the contents of a disc image to a directory.

nodtool extract /path/to/game.iso [outdir]

For Wii U VC titles, use content/hif_000000.nfs:

nodtool extract /path/to/game/content/hif_000000.nfs [outdir]

convert

Converts any supported format to raw ISO.

nodtool convert /path/to/game.wia /path/to/game.iso

verify

Hashes the contents of a disc image and verifies it.

nodtool verify /path/to/game.iso

Library example

Opening a disc image and reading a file:

use std::io::Read;

use nod::{Disc, PartitionKind};

fn main() -> nod::Result<()> {
    let disc = Disc::new("path/to/file.iso")?;
    let mut partition = disc.open_partition_kind(PartitionKind::Data)?;
    let meta = partition.meta()?;
    let fst = meta.fst()?;
    if let Some((_, node)) = fst.find("/MP3/Worlds.txt") {
        let mut s = String::new();
        partition
            .open_file(node)
            .expect("Failed to open file stream")
            .read_to_string(&mut s)
            .expect("Failed to read file");
        println!("{}", s);
    }
    Ok(())
}
