For the average user, a compressed or slightly altered file might work fine in an emulator. However, for historians and developers, bit-perfect copies are essential:

: The project accounts for factors like drive offsets and subchannel data, which are often ignored by standard burning software but are crucial for copy protection and metadata. redump

Redump (formally known as Redump.org) is an international disc preservation project and database dedicated to archiving precise digital copies of optical media. Unlike standard "piracy" groups that focus on accessibility or file size, Redump prioritizes , ensuring that the digital image of a disc is indistinguishable from the physical original. The Core Mission: Preservation Over Convenience For the average user, a compressed or slightly

: Each entry in the database includes detailed metadata, such as the disc's serial number, ring code (the physical text etched near the center of the disc), and version information. How the Redump Process Works Unlike standard "piracy" groups that focus on accessibility

The primary goal of Redump is to create a definitive record of every software disc ever released, including video games, operating systems, and application software. This is critical because physical optical discs—CDs, DVDs, and Blu-rays—suffer from "disc rot," a chemical degradation process that can make data unreadable over time.

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