|
|
|
Library for traversing & reading Nintendo Optical Disc (GameCube and Wii) images.
|
|
|
|
Originally based on the C++ library [nod](https://github.com/AxioDL/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)
|
|
- GCZ
|
|
- TGC
|
|
|
|
## CLI tool
|
|
|
|
This crate includes a command-line tool called `nodtool`.
|
|
|
|
Download the latest release from the [releases page](https://github.com/encounter/nod-rs/releases),
|
|
or install it using Cargo:
|
|
|
|
```shell
|
|
cargo install --locked nodtool
|
|
```
|
|
|
|
### info
|
|
|
|
Displays information about a disc image.
|
|
|
|
```shell
|
|
nodtool info /path/to/game.iso
|
|
```
|
|
|
|
### extract
|
|
|
|
Extracts the contents of a disc image to a directory.
|
|
|
|
```shell
|
|
nodtool extract /path/to/game.iso [outdir]
|
|
```
|
|
|
|
For Wii U VC titles, use `content/hif_000000.nfs`:
|
|
|
|
```shell
|
|
nodtool extract /path/to/game/content/hif_000000.nfs [outdir]
|
|
```
|
|
|
|
### convert
|
|
|
|
Converts any supported format to raw ISO.
|
|
|
|
```shell
|
|
nodtool convert /path/to/game.wia /path/to/game.iso
|
|
```
|
|
|
|
### verify
|
|
|
|
Hashes the contents of a disc image and verifies it.
|
|
|
|
```shell
|
|
nodtool verify /path/to/game.iso
|
|
```
|
|
|
|
## Library example
|
|
|
|
Opening a disc image and reading a file:
|
|
|
|
```rust
|
|
use std::io::Read;
|
|
|
|
// Open a disc image and the first data partition.
|
|
let disc = nod::Disc::new("path/to/file.iso")
|
|
.expect("Failed to open disc");
|
|
let mut partition = disc.open_partition_kind(nod::PartitionKind::Data)
|
|
.expect("Failed to open data partition");
|
|
|
|
// Read partition metadata and the file system table.
|
|
let meta = partition.meta()
|
|
.expect("Failed to read partition metadata");
|
|
let fst = meta.fst()
|
|
.expect("File system table is invalid");
|
|
|
|
// Find a file by path and read it into a string.
|
|
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);
|
|
}
|
|
```
|
|
|
|
Converting a disc image to raw ISO:
|
|
|
|
```rust
|
|
// Enable `rebuild_encryption` to ensure the output is a valid ISO.
|
|
let options = nod::OpenOptions { rebuild_encryption: true, ..Default::default() };
|
|
let mut disc = nod::Disc::new_with_options("path/to/file.rvz", &options)
|
|
.expect("Failed to open disc");
|
|
|
|
// Read directly from the open disc and write to the output file.
|
|
let mut out = std::fs::File::create("output.iso")
|
|
.expect("Failed to create output file");
|
|
std::io::copy(&mut disc, &mut out)
|
|
.expect("Failed to write data");
|
|
```
