Redump May 2026

If you want to preserve your own physical discs, follow the guides on Redump.org. If you want to find verified disc images for software you own, you will need to look elsewhere (e.g., the Internet Archive), then use the Redump database to confirm their integrity.

If you are a casual retro gamer who plays Super Mario World on a hacked SNES Classic, you might never need a Redump. But if you are a historian, a developer working on an emulator, or a hardware tinkerer building a MiSTer FPGA—Redump is your oxygen.

They are the silent guardians, the archivists with soldering irons, the people who spend 14 hours configuring a DOS driver for a Plextor drive just to verify a single track index on a copy of Myst.

Redump proves that the internet is not just for cat videos and arguments. Sometimes, it is for saving the pixels and audio samples of our childhood from the great silent void of bit rot.

So the next time you see a ".cue" and ".bin" file that works flawlessly, tip your hat to the dumpers. They are the librarians of the apocalypse, and they are winning.

: They aim for perfect, error-free copies that match the original manufacturing metadata. Verification Database

: You can use their database to verify your own dumps by comparing SHA-1 hashes to ensure they are authentic. Community Preservation

: The project is maintained by volunteers who have preserved over 50,000 PC discs and thousands of console games for systems like PlayStation, Sega Saturn, and GameCube. Redump Forum How to Use Redump Information: So how do I compare my dump vs. redump.org ? (Page 1)

Redump (specifically redump.org) is a specialized disc preservation project and community database dedicated to cataloging and verifying optical disc data. Its primary goal is to ensure that backups of physical media—such as CDs, DVDs, and Blu-rays for video games and software—are bit-perfect "1:1" copies of the original retail versions. Core Purpose and Methodology

The project maintains a massive database of "DAT" files, which contain metadata like file names, sizes, and unique cryptographic hashes (CRC32, MD5, SHA-1) for specific tracks and sectors of a disc.

Verification: Users can use a rom manager like Clrmamepro or dedicated CLI tools to compare their own game dumps against the Redump database. A match confirms the dump is authentic and uncorrupted. redump

Preservation Standards: Redump sets strict guidelines for dumping. For example, it requires specific hardware, such as certain MediaTek-based Blu-ray drives, to accurately read subchannel data or lead-out sections that common drives might miss. Key Components of a "Redump" Set

When you see files referred to as "Redump-compliant," they typically follow a specific structure:

Redump.org is a digital preservation project and community dedicated to creating an accurate, verified database of every video game ever released on optical media (CD, DVD, Blu-ray, etc.). Core Purpose

The project focuses on "redumping" games to ensure they are preserved with 1:1 accuracy. Unlike early scene groups that might have removed copy protection or modified files, Redump aims for perfect replicas that include original disc offsets, subchannel data, and exact checksums. Key Methodology

Standardized Tools: The primary tool is redumper, a cross-platform CLI program that handles the complex task of reading optical media.

Verification: A "clean" dump must be verified by multiple contributors. If two people in different parts of the world dump the same disc and get identical checksums (MD5, SHA-1), the entry is considered verified in the database.

Detailed Metadata: Submissions require more than just the game files; they often include ring codes (physical numbers on the disc), barcodes, and logs that detail the drive used. Dumping Process by System

The complexity of a dump depends on the system's hardware and disc type: Redump.org

Preserving History: Understanding Redump.org Redump.org is a disc preservation database and internet community dedicated to collecting precise and accurate information about video games released on optical media. In the world of digital archiving, it is considered the "gold standard" for disc-based games, much like No-Intro is for cartridge-based systems. What is a "Redump"?

A "dump" is a digital copy of a physical disc. A "redump" refers to the process of verifying or re-copying a disc to ensure it matches the original perfectly. The goal of the Redump project is to create a definitive database where every game has a verified, 1:1 digital representation. Why Precision Matters

Digital preservation isn't just about making a game playable; it's about authenticity. Many early "rips" of games were "bad dumps" that contained errors, were missing data, or had been modified by hackers.

Verification: Redump uses checksums (like MD5, SHA-1, or CRC32) to verify that a file exactly matches the original retail disc.

Standardization: The community follows strict dumping methods, often requiring specific hardware like compatible Blu-ray or DVD drives and specialized software like DiscImageCreator.

Completeness: Unlike some formats that compress data, Redump sets prioritize keeping the original content, including subchannel data and system-specific partitions, even if it results in larger file sizes. The Redump Database | Aspect | Summary | | :--- |

The project maintains a massive searchable database of thousands of titles across dozens of systems. Redump.org

Redump.org is a massive, community-driven disc preservation project and database dedicated to archiving precise digital "blueprints" of optical media. Unlike standard game ripping, Redump focuses on creating high-quality, verified copies that match the original physical disc bit-for-bit to ensure long-term digital preservation. Redump Wiki Core Principles and Philosophy Verification Through Redumping:

The project's name comes from its central rule: a disc must be dumped at least twice by different people to be marked as "verified" in the database. If two independent users get the exact same checksum (hash) from their physical copies, the dump is considered a perfect digital replica. No ROM Hosting:

Redump does not host game files or ROMs on its website. Instead, it provides a metadata library (in the form of

files) that users use to verify their own local files against the official community standard. Archival Integrity:

The goal is to preserve "original" data, including regional variations and different print runs (revisions) of the same title. Redump Wiki Redump.org

Redump is a community-driven project focused on creating precise, 1:1 backups (dumps) of optical media games (CD, DVD, Blu-ray) for preservation and emulation purposes. Unlike standard ISO rips, Redump ensures the entire disc structure—including audio tracks, pregaps, and subchannel data—is perfectly captured. 1. What is Redump?

Goal: To preserve video game data by creating accurate, verified "blueprints" of console and PC game discs.

Method: Multiple users dump the same game to verify checksums against each other, ensuring the data is identical to the retail master.

Database: Redump.org acts as a repository for this data, providing datfiles, guides, and a "miss list" of games still needed for preservation.

Scope: Supported systems include PlayStation 1/2/3, Xbox/360, Sega Saturn/Dreamcast, GameCube, and various PC CD-ROM titles. 2. Key Components of Redump

BIN/CUE: The standard format for Redump dumps, where .bin contains the data and .cue describes the track layout.

Redumper/DIC: Specialized software (redumper CLI, DiscImageCreator) is used to read discs accurately, including those with tricky copy protection.

Subchannel Data: Crucial for games with libcrypt (PS1) or specialized ring protections, stored in .sub files. For a disc to be marked "Verified" in

AccurateRips/Offsets: The process accounts for the drive's read/write offset to ensure perfect byte-for-byte matching, which is especially important for audio tracks. 3. How to Perform a Redump

Preparation: Use a capable optical drive (e.g., specific LG, Plextor, or Optiarc models) and download the necessary tools from the wiki.

Dumping: Use redumper via command line to read the disc. It handles the raw reading and automatically generates the necessary files.

Verification: Compare the checksums of your dump (.bin) against the Redump database using the provided .dat files.

Submission: If the dump is new or missing, you can submit the dump along with the log file, ring code, and barcode to the Redump forum for verification. 4. Common Conversions & Tools Redump.org

For a disc to be marked "Verified" in the Redump database, two separate users with different hardware configurations must dump the disc and produce identical hash values. High-value or obscure discs often require a third or fourth dump to ensure no read errors.

To understand Redump, you must understand how they organize their database.

You cannot use a standard DVD drive to dump certain disc types accurately. You need specific hardware to bypass disc protection.

For years, the Sega Saturn port of Shrek was "undumpable." Every copy failed hashing. Redump investigators discovered that the subchannel data on the official disc contained uninitialized gibberish that varied from minute to minute. They had to develop a new method to "ignore" the dynamic subchannel while validating the static data.

We are losing the war against entropy. CD-Rs from the early 2000s are already becoming coasters. Pressed discs from the late 80s are delaminating.

Redump has shifted its focus in recent years from "collecting" to "racing." It is now a race against disc rot.

To combat this, Redump has extended its scope to include:

In short: If you rip an audio CD to MP3, you lose data. If you rip it to a Redump-verified BIN/CUE, you have a perfect archive of the original disc.
