Redump

Redump's model of distributing checksums rather than files is a carefully considered legal strategy.

In practice, the two projects are complementary. A retro game collector building a complete software library would likely use No-Intro DATs for their NES, SNES, and Game Boy collections, and Redump DATs for their PlayStation, Saturn, and Dreamcast libraries. In some cases, their definitions of what constitutes a "game" also differ; for example, No-Intro may exclude bonus discs or video DVDs that came with a game that Redump will catalog. Together, they form a comprehensive, if unofficial, standard for the entire history of physical game media.

: The project aims for "bit-perfect" accuracy. It sets itself apart by requiring dumps to be made from original physical discs , never from internet-sourced images.

The primary tool utilized by modern Redump contributors is , a highly advanced command-line tool designed specifically for deep, low-level optical disc analysis. DIC bypasses standard operating system file systems to read individual sectors, analyze sub-channel information, and handle complex multi-track formats (such as mixed-mode CDs containing both game data tracks and red-book audio tracks). 3. Cryptographic Hashing redump

The Redump process is rigorous. A user doesn't just dump a disc; they contribute to a database.

Redump rejects this approach. The project operates on the principle of .

Modern emulators are increasingly built to support raw, uncompromised Redump images natively. Because these dumps preserve original copy-protection checks, developers of emulators can write software that bypasses or mimics the real hardware checks authentically, rather than relying on hacked, unstable game files.

As the video game industry continues to evolve, the Redump project remains committed to its mission of data preservation. With a growing community of contributors and supporters, Redump is poised to:

The resulting files are hashed (usually via HashTab or ImgBurn) to produce a unique signature. In some cases, their definitions of what constitutes

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

Most standard PC drives will intentionally misread or skip errors. Redump requires specific "readers" known to support "subchannel reading" and "overreading into lead-out." The most famous tools are old IDE Plextor drives (like the PX-760A or PX-755) or certain LG GDR-8164B DVD drives.

At its core, dedicated to a single, ambitious goal: to collect precise and accurate information about every video game ever released on optical media—CDs, DVDs, Blu-rays, and everything in between.
