Redump -
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.
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

: Unlike older formats that might compress or strip data, Redump focuses on "perfect" dumps. This leads to better compatibility with emulators and more reliable long-term storage. Verification System
: A game is only marked as "verified" in their database after multiple independent users provide matching hashes (checksums) from different discs, which eliminates errors caused by scratches or bad drives. Comprehensive Metadata
: Beyond just the game data, they document regional variants, revisions, ring codes, and even specific languages found on the disc. Standard for Archivists
: Because of its strict guides and verification, Redump is the preferred source for digital archivists and serious collectors. Redump Forum Potential Drawbacks Why are verifications checked manually? (Page 1)
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

Ethical Tightropes and Legal Gray Zones
No essay on Redump can ignore the legal and ethical complexities of disc image preservation. The project itself does not host or distribute game files; it maintains a database of checksums, logs, and metadata. To actually obtain a Redump-verified image, a user must either dump their own disc (the preferred method) or find a copy from a third party. This careful distancing allows Redump to operate in a legal gray area, protected by the same logic as a card catalogue in a library that does not contain the books themselves.
Nevertheless, the project exists in tension with copyright law, which in many jurisdictions (including the United States) prohibits the circumvention of copy protection, even for preservation. While Redump does not “crack” games, the act of reading subchannel data can technically violate the Digital Millennium Copyright Act (DMCA). Critics argue that Redump enables piracy by providing a perfect blueprint for reproduction. Supporters counter that the project’s strict verification standards and non-commercial ethos serve the public good, preserving digital culture that corporations have repeatedly shown no interest in saving—especially for obscure or commercially unsuccessful titles.
What is Redump?
Redump is a collaborative, global project dedicated to creating accurate, verifiable, and complete disc image dumps of optical media (CDs, DVDs, Blu-rays, HD-DVDs, and even some console cartridges and tapes).
Its primary goal is software preservation. Unlike simply copying files from a disc, Redump aims to capture the entire physical and logical structure of the original medium, including subchannel data, error correction codes, and mastering information. This ensures the digital copy is a perfect 1:1 replica (a "bit-perfect" dump) of the original disc.
The Gold Standard: LG (Hitachi) "Orange" Drives
For systems like the Sega Saturn and Sega Dreamcast, these drives are mandatory.
- Model Series: GH1, GDR-8081N, GDR-8082N, GDR-8083N, GDR-8084N.
- Why? These drives have a specific firmware bug that allows them to read the "Lead-in" and "Lead-out" areas of discs that other drives physically skip.
- Identification: Look for the orange colored slider mechanism inside the drive tray. These are increasingly rare and expensive.
