# Dolphin RVZ disc images

The [github.com/bodgit/rvz](https://github.com/bodgit/rvz) package reads the [RVZ disc image format](https://github.com/dolphin-emu/dolphin/blob/master/docs/WiaAndRvz.md) used by the [Dolphin emulator](https://dolphin-emu.org).

* Handles all supported compression methods; Zstandard is only marginally slower to read than no compression. Bzip2, LZMA, and LZMA2 are noticeably slower.

How to read a disc image:

```golang

package main

import (

	"io"

	"os"

	"github.com/bodgit/rvz"

)

func main() {

	f, err := os.Open("image.rvz")

	if err != nil {

		panic(err)

	}

	defer f.Close()

	r, err := rvz.NewReader(f)

	if err != nil {

		panic(err)

	}

	w, err := os.Create("image.iso")

	if err != nil {

		panic(err)

	}

	defer w.Close()

	if _, err = io.Copy(w, r); err != nil {

		panic(err)

	}

}

```

## rvz

The `rvz` utility currently allows you to decompress an `.rvz` file back to its original `.iso` format.

A quick demo:
