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.
Here is everything you need to know about Redump, how it works, and why it is critical for digital preservation. What is Redump?
Redump is not just a collection of files; it is a community.
| Feature | Redump | No-Intro | | :--- | :--- | :--- | | | Disc-based media (CD, DVD, Blu-ray, GD-ROM, UMD) | Cartridge-based media (ROM chips) and digital downloads | | Verification Logic | Multiple independent dumps; requires two unique submissions for "verified" status | Single verified dump from a good source; community consensus | | Data Complexity | Very high; captures subchannel data, lead-in/out, and complex disc structures | Relatively simpler; extracts raw binary data from a ROM chip | | Tools | Redumper, DIC, MPF, Aaru, specialized Plextor drives for CDs | Tools like ClrMamePro, ROMVault, and various dumping hardware | | Community | Smaller, more technically focused on the nuances of optical media | Larger, broader focus on all cartridge-based systems | redump
Redump is a project and community dedicated to preserving the original contents of optical-disc-based video games and software. Its goal is to create an accurate, verifiable archive of disc images and associated metadata so collectors, researchers, preservationists, and enthusiasts can access authentic copies of original releases for historical and archival purposes.

Within the world of game preservation, two major projects stand side-by-side: and No-Intro . While they share a common goal of accuracy, their domains and methodologies are different. Understanding the distinction is crucial for any serious archivist. Redump is not a product of a single

Every year, thousands of game discs degrade beyond recovery, taking their unique data—from a niche regional release to a developer's final patch—with them. Redump is a race against time to document these discs before they are lost forever. By creating a permanent digital blueprint, the project ensures that even if every physical copy of a game disintegrates, the knowledge of its data structure, copy protection, and precise version differences is not erased from history.
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. What is Redump
Redump.org is a massive, community-driven disc preservation project and database dedicated to archiving precise digital "blueprints" of optical media. Unlike standard game ripping, Redump focuses on creating high-quality, verified copies that match the original physical disc bit-for-bit to ensure long-term digital preservation.

The process of contributing to Redump is not for the faint of heart, but it has been made increasingly accessible. The project provides extensive, step-by-step dumping guides for a wide variety of systems and media types. The general process is as follows:
Tools like and Universal ROM Sorter (URS) have become indispensable for collectors. They are designed to take a chaotic, flat folder of disc images and automatically sort them into a clean, organized folder hierarchy based on the metadata in Redump's DAT files. These applications can flag incorrect dumps, identify missing files, and even rename images to match a standardized naming convention, making a large library navigable and consistent.
