Frequently Asked Questions

What is RVZStudio?

A cross-platform desktop application that batch converts GameCube and Wii disc images to the RVZ format, verifies RVZ integrity, and extracts RVZ files back to ISO, WBFS, GCZ, WIA, CISO or TGC.

Which platforms are supported?

Windows, Linux and macOS on both x64 and ARM64. See Getting Started for installation instructions.

Is RVZStudio free?

Yes. It is open source under the GNU General Public License v3.0 (see LICENSE.txt).

Do I need Dolphin or DolphinTool installed separately?

No. RVZStudio's primary engine (RVZSharp) is built in. Release packages bundle 7za as an archive fallback on every platform, and Windows packages also bundle DolphinTool as an optional conversion/verification fallback; RVZStudio looks for them in its own folder and works without them.

Which input formats can I convert?

.iso, .gcm, .wbfs, .gcz, .wia, .ciso, .wbi, .tgc, .nfs, .nkit.iso and the archives .zip, .7z, .rar containing any of those.

Can I convert RVZ back to ISO?

Yes — use the Extract from RVZ tab. Supported outputs are ISO, WBFS, GCZ, WIA, CISO and TGC.

Can I browse the files inside a disc image?

Yes — the Explorer tab opens any supported image (ISO, RVZ, WIA, GCZ, CISO, WBFS, TGC, NFS) and shows its file system. You can expand folders, copy individual files or whole folders out, and compute per-file SHA-256 hashes without converting the image.

What compression should I use?

zstd at level 5 with a 128 KB block size is the recommended default. See the Settings Reference for presets.

Is conversion lossless?

Yes. RVZ is a lossless container: no game data is discarded. RVZSharp decodes RVZ back to the original ISO byte-for-byte.

Does it work without an internet connection?

Yes. Internet access is only used for the optional update check and anonymous error/usage reporting.

What data does RVZStudio send?

Where are the settings stored?

RVZStudio does not persist UI settings between sessions; each batch uses the defaults unless you change the controls for that run. Logs are stored in the platform-specific locations listed in Troubleshooting.

Can multiple conversions run at once?

No. Only one operation (conversion, verification or extraction) can run at a time; the other actions are disabled until it finishes. Click Cancel to stop the current operation.

Where can I report bugs or request features?

Open an issue at https://github.com/purelogiccode/RVZStudio/issues. Include your OS, RVZStudio version and the relevant log output.
