Redump | Hot!

The project stands at the center of this movement. It is the gold standard for optical disc preservation. What is Redump?

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

By utilizing rigorous dumping standards, the Redump community ensures that:

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.

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. redump

In the US, the Digital Millennium Copyright Act (DMCA) makes it illegal to circumvent copy protection, even for archival purposes. The Librarian of Congress grants exemptions every three years, but the language is narrow.

Hidden metadata sectors on the disc that contain sub-code tracking data (such as CD-Text, track timings, and regional copy protection flags).

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"?

Back in the 1990s and early 2000s, many game backups were made using simple ripping software that produced ISO files. These files frequently omitted crucial audio tracks or scrambled data sectors that helped combat piracy.

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

Redump approaches archiving through the philosophy of the . The project stands at the center of this movement

For many retro systems—particularly CD-ROM-based platforms like the PlayStation, Sega Saturn, and PC—Redump dumpers are required to use specific, highly accurate optical drives. Legendary drives like the series are highly sought after because they allow low-level access to subchannel data and support precise read offset configurations. 2. Standardized Extraction Software

A massive project aiming to catalog everything —including every firmware version, bad dump, hack, and homebrew software, primarily for vintage home computers like the Amiga, Commodore 64, and early PCs. How to Get Involved and Contribute

By utilizing strict hardware requirements, standardized software workflows, and mathematical verification via cryptographic hashing, Redump ensures that our digital history remains permanently uncorrupted and accessible for centuries to come. The Philosophy of "Bit-Perfect" Archiving
