Why does Redump exist? Because plastic rots.
Unlike a cartridge (which is essentially a solid-state ROM chip), optical discs are fragile. They suffer from: redump
Furthermore, preservation isn't just about the game's executables. It is about context. A soundtrack, a hidden CD audio track, a specific subchannel data error that triggers anti-piracy—these are artifacts of history. Redump captures all of it. They preserve the weirdness of the physical medium, not just the software.
Many PS1 games hide "redbook audio" (standard CD audio tracks) in the pregap index. To hear it, you had to physically rewind the CD from Track 1 into a negative time index. Redump was the first to systematically document and preserve these hidden audio tracks that most commercial ripping tools ignored.
Redump’s value extends far beyond simply allowing someone to play an old game on an emulator. The project has proven essential for understanding the material history of software production. By comparing dumps of the same game released in different regions or at different times, researchers can discover:
In one celebrated case, Redump’s logs allowed historians to recover the exact audio track order for a misprinted edition of Sonic CD for the Sega CD, proving that the manufacturing error itself—not the intended track order—was what millions of players actually experienced.
Redump isn't just theory. They have produced tangible wins for history.

Redump.org is a massive digital preservation project and community dedicated to creating a comprehensive, high-fidelity database of video games released on optical media. Unlike casual ROM-sharing sites, Redump focuses on archival accuracy, providing "blueprints" of original discs to ensure that software history is perfectly preserved. 1. Core Mission and Standards
The primary goal of Redump is to document every detail of a disc, including track offsets, subchannel data, and precise checksums.
Disc Integrity: Redump advocates for "clean" dumps that include the gaps between tracks, making them more accurate representations of the original factory-pressed media.
Verification: The community uses manual verification and cross-referencing of multiple dumps from different users to confirm a game's "correct" digital signature.
Strict Guidelines: To contribute, users must follow specific guides and often use approved hardware, such as certain Plextor drives, to ensure data is read without error or offset shifts. 2. Supported Platforms
Redump maintains records for a vast array of optical-media systems. While its database is constantly growing, it is particularly known for: Redump Wiki - Redump.org
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.
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: The Ultimate Guide to Optical Disc Preservation Redump.org is a dedicated disc preservation project and database aimed at archiving precise digital copies (dumps) of optical media, including games for consoles and PCs. Unlike other "ROM" sets that may prioritize small file sizes, Redump focuses on 1:1 accuracy
, ensuring that every bit of data—from the game files to the specific disc structures—is preserved exactly as it appeared on the original retail media. Why Redump Matters
In the world of digital preservation, not all copies are equal. Redump is widely considered the "gold standard" for disc-based systems because: Verification
: Every entry in the database is verified by multiple users or cross-referenced against known physical copies to ensure the data is "clean" and free of read errors. Completeness
: The project tracks regional variants, revisions (v1.0 vs v1.1), and even specific "ring codes" printed on the physical disc to distinguish between different manufacturing runs. Hardware Compatibility
: 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

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
