Redump

If the hash matches an existing entry, the dump is verified.

If you are looking for specific dumping instructions for a console like the Sega Saturn or PS2, I can provide more detailed information. Share public link

The community "dumps" discs (CDs, DVDs, Blu-rays, GD-ROMs, UMDs) using specific, rigorous hardware and software techniques. They then calculate cryptographic hashes (like MD5 or SHA-1) and submit the disc’s metadata (track layout, pregaps, offsets) to the database. If two people in different countries dump the same game and get the exact same hash, the disc is confirmed as a "good dump."

: Preservation must include hidden data tracks, audio offsets, and sub-channels required for emulation. redump

The act of redumping games walks a fine line between preservation, legality, and personal ethics. If you are considering digitizing your own game collection:

Redump is a project and community dedicated to preserving the original contents of optical-disc-based video games and software. Its goal is to create an accurate, verifiable archive of disc images and associated metadata so collectors, researchers, preservationists, and enthusiasts can access authentic copies of original releases for historical and archival purposes.

Once your dump is complete, submit the generated logs and cryptographic hashes to the Redump staff. If your data matches someone else’s unverified dump, you’ve just helped officially certify a piece of gaming history. The Bottom Line

ImgBurn is the most common tool used.

This article provides an in-depth look at what Redump is, how it works, why it matters, and how you can participate. 1. What is Redump?

By documenting the exact structure, data tracks, and audio sub-channels of these discs, Redump ensures that if a digital backup matches their database, it is a 100% accurate, uncompromised replica of the original factory press. The Core Philosophy: "Bit-Perfect" Preservation

Sony PlayStation, Sega Saturn, Sega CD, TurboGrafx-CD, 3DO

The hash is compared against the Redump.org database. If the hash matches an existing entry, the dump is verified

Not all disc drives are created equal. Redump requires specific optical drives—most notably certain models of Plextor, Asus, and LG drives—that can read sub-channel data and accurately report read offsets. 2. Drive Offset Calibration

Adjusting for the minute internal calibration differences between laser hardware brands to guarantee that data bytes map to their exact, original positions. Why Redump Matters: The Threat of Digital Decay

: Because these are exact copies, they are essential for developers working on emulators or hardware clones that require 100% accurate data to function correctly. How to Get Started with Redump Share public link The community "dumps" discs (CDs,

Redump cross-references these hashes across multiple independent dumps of the same game disc. When multiple preservationists across the world submit identical hashes for the same title, the dump is verified and marked as a "true" match in the database. The Redump Dumping Workflow
