Xbox’s new plan to let players digitise the discs they already own is not the first swing at physical-to-digital preservation. Emulation and archival communities have been ripping cartridges and pressing DVDs into 1:1 dumps for two decades. The trick is doing it in a way that survives verification: a clean rip matches a known good hash, so you can prove what you have is the original master and not a bit-rotted copy.
We looked at seven desktop tools people use to dump discs and carts across the last five console generations. Two are the standard for Wii and GameCube preservation, two are hardware-companion apps for cart dumpers, three cover the wider disc and metadata pipeline. All run on Windows, most run on macOS and Linux.
What to look for
- Redump-accurate output. Redump.org publishes hashes for every disc pressing; a dumper that matches those hashes is a dumper you can trust.
- CRC / SHA-1 verification built into the app, not as an afterthought.
- Format flexibility: RVZ or NKit for Wii and GameCube, CHD for arcade and CD-based consoles, XCI or ROM for cartridges.
- Hardware compatibility with the dumpers you own (a modified Wii, an ODE, a Sanni Cartridge Reader, a USB IDE bridge).
- A metadata pipeline so the ripped file lands in your library with the right name, region, and cover.

1. Dolphin – Best for Wii and GameCube disc dumping via a modded console
Dolphin is the Wii and GameCube emulator, but it doubles as a converter: point it at a raw ISO you dumped with CleanRip and it converts to RVZ (its own lossless compressed format), verifies against known hashes, and shows you exactly which pressing you have. The Verify tab in properties is the tool most people forget exists.
Where it falls short: Doesn’t dump discs itself — you need CleanRip on a Wii or a compatible drive. The interface is emulator-first, not library-manager-first.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Windows, macOS, Linux.
Download: dolphin-emu.org.
Bottom line: The verifier and format converter for every Wii or GameCube dump you make.
2. CleanRip – Best for Wii and GameCube dumping on-console
CleanRip is Wii homebrew that dumps discs on the console itself, over USB or SD. You install the Homebrew Channel, drop CleanRip on the SD, boot it, and it reads the disc, splits into 2 GB parts if needed, and calculates hashes on the fly. The output is a raw ISO plus a matching hash file.
Where it falls short: Requires a modded Wii or Wii U in vWii mode. Slow on stock drives; a modchip helps.
Pricing:
- Free: Everything.
- Paid: None.
Platforms: Wii / Wii U vWii; the output is read on desktop by Dolphin.
Download: Wiibrew.
Bottom line: The reference dumper for Wii/GameCube discs, universally accepted by Dolphin and Redump.
3. RVZ / NKit – Best for compressing Wii/GameCube dumps losslessly
RVZ (built into Dolphin) and NKit are the two lossless compression formats for Wii/GameCube dumps. Both strip the encrypted junk and dummy data that adds nothing to gameplay but bloats the file, and both convert back to a bit-identical ISO when you need one. A 4.7 GB dual-layer Wii disc typically drops to under 2 GB.
Where it falls short: NKit is not officially endorsed for archival by all communities (RVZ is preferred). Some verification workflows only accept the raw ISO.
Pricing:
- Free: Both.
- Paid: None.
Platforms: Windows, macOS, Linux.
Download: RVZ is built into Dolphin; NKit lives at gbatemp.net.
Bottom line: Convert your raw dumps to RVZ. You’ll save 40-60% of your disk without losing a bit.
4. DiscImageCreator – Best for Redump-standard PC-based CD/DVD dumping
DiscImageCreator (DIC) is the tool Redump.org uses to build their database. It handles CDs (PS1, Saturn, Dreamcast, TurboGrafx-CD) and DVDs (PS2 in some cases), dumps subchannel data, calculates every hash Redump wants, and outputs the bin/cue + accompanying files a dump needs to be accepted upstream.
Where it falls short: Windows only. Command-line first — the GUI is a wrapper.
Pricing:
- Free: All features.
- Paid: None.
Platforms: Windows.
Download: github.com/saramibreak/DiscImageCreator.
Bottom line: The tool if you’re contributing back to Redump. Also the most rigorous choice for personal PS1/Saturn/Dreamcast archives.
5. GameCube Memory Card Recovery – Best for save-file preservation
GameCube Memory Card Recovery does what the name says: reads a real memory card through a modified reader (GC Loader, GCMM on Wii, or an adapter) and writes out a .gci file per save that Dolphin and every emulator can import.
Where it falls short: Requires reader hardware. Won’t help for cards that have physical damage.
Pricing:
- Free: All features.
- Paid: None.
Platforms: Windows.
Download: github.com/suloku/gcmm for the on-console version, plus desktop tools that import the output.
Bottom line: The way to keep 20-year-old memory card saves before the batteries and the corrosion win.
6. Sanni Cartridge Reader – Best for cart dumping across the retro catalogue
Sanni Cartridge Reader is an open-source hardware project — an Arduino-based dumper that reads N64, SNES, NES, Game Boy, Game Boy Advance, Genesis, Master System, and more. The desktop side is the firmware flasher and the GUI that browses dumps off the reader’s SD card. Complete kits are around $100; built units run $150-200.
Where it falls short: You have to buy or build the hardware. The firmware moves fast, so keep an eye on updates.
Pricing:
- Free: Firmware and desktop tools.
- Paid: Hardware costs $100 kit or $150-200 built.
Platforms: Windows, macOS, Linux (for firmware flashing and SD reading).
Download: github.com/sanni/cartreader.
Bottom line: The universal cart dumper for the retro shelf. Buy or build once, dump everything you own.
7. Redump Verification Tool – Best for verifying dumps against the database
Redump Verification Tool (and its cousins like Rebuild DAT-o-Matic and rvhash) takes a dump and checks it against the Redump database of known-good hashes. Green means your rip matches the master; red means something’s off — a bad drive, a scratched disc, or a pressing variant.
Where it falls short: Only as good as Redump’s database. Newer or rare releases may not be catalogued yet.
Pricing:
- Free: All features.
- Paid: None.
Platforms: Windows, macOS, Linux (JVM).
Download: redump.org.
Bottom line: The final step of any archival session. If it doesn’t verify, redump the disc.
How to pick the right one
- If you own a modded Wii and want to dump your GameCube collection: CleanRip to rip, Dolphin to verify, RVZ to compress.
- If you’re contributing to Redump: DiscImageCreator, always.
- If your collection is mostly cartridges: Sanni Cartridge Reader, then verify.
- If you’re saving memory cards: GameCube Memory Card Recovery first, everything else after.
- If you already have dumps and want them clean: RVZ / NKit to compress, Redump Verification Tool to check.
FAQ
Is it legal to dump my own console games? In most jurisdictions, making a personal backup of media you own is legal or falls into a grey area. Distributing the dumps is not. Rules vary by country — check yours before you post anything.
What’s the difference between a Redump dump and a No-Intro dump? Redump handles optical media (CDs, DVDs) with exhaustive verification including subchannel data. No-Intro handles cartridges and ROMs. Both aim for bit-perfect archival; they just cover different formats.
Can I dump a PS3 or Xbox 360 disc on a PC? Not with a standard drive. You need specific drives that expose raw sectors (Blu-ray drives with modified firmware for PS3, LG Bluray drives with 3K3Y firmware for Xbox 360). Same tools, different hardware.
How much space does a full archive take? A single-layer Wii disc compressed to RVZ is around 1-2 GB. A dual-layer Xbox 360 disc in raw form is 6-8 GB. A cartridge dump is 8-64 MB. A serious collection lives comfortably on a 4 TB drive.
Do these tools work on macOS or Linux? Dolphin, RVZ conversion, Sanni Cartridge Reader firmware, and Redump Verification Tool all run cross-platform. DiscImageCreator and CleanRip’s desktop wrappers are Windows-first, though DIC has been reported to work under Wine.
