Redump

A cyclic redundancy check to detect accidental changes to raw data.

Redump is not a product of a single company or a small team in a lab; it is a monument built by a global community of volunteers. Getting started is a deliberate process, designed to ensure new members understand the project's high standards before they contribute. redump

In an era dominated by ephemeral cloud storage and automatic updates, the physical video game disc or cartridge of the 1990s and 2000s represents a fragile archive. These discs—pressed with CD, DVD, or Blu-ray technology—are susceptible to “disc rot,” a chemical degradation of the reflective layer and polycarbonate substrate that renders data unreadable. As millions of optical media disks approach their projected lifespan limit of 20 to 50 years, one volunteer-driven initiative stands as the most meticulous archivist of our interactive heritage: .

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.
