To combat this, Redump has extended its scope to include:
: A "clean" dump must be verified by multiple contributors. If two people in different parts of the world dump the same disc and get identical checksums (MD5, SHA-1), the entry is considered verified in the database.
Think of it as the Library of Congress for optical media, but instead of storing the books, they store the card catalog and the blueprint for how to rebuild the book perfectly.
First, a crucial distinction:
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

The Complete Guide to Redump: Preserving Video Game History with Bit-Perfect Precision redump
: Many discs contain hidden data, unused assets, or specific regional differences that are lost if the disc is not archived in its entirety.
Digital preservation isn't just about making a game playable; it's about authenticity. Many early "rips" of games were "bad dumps" that contained errors, were missing data, or had been modified by hackers.
Redump is an international group and website focused on archiving console games from platforms that used optical media, such as PlayStation 1, PlayStation 2, Sega Saturn, Dreamcast, Xbox, and more. To combat this, Redump has extended its scope
Nevertheless, the project exists in tension with copyright law, which in many jurisdictions (including the United States) prohibits the circumvention of copy protection, even for preservation. While Redump does not “crack” games, the act of reading subchannel data can technically violate the Digital Millennium Copyright Act (DMCA). Critics argue that Redump enables piracy by providing a perfect blueprint for reproduction. Supporters counter that the project’s strict verification standards and non-commercial ethos serve the public good, preserving digital culture that corporations have repeatedly shown no interest in saving—especially for obscure or commercially unsuccessful titles.
To create a Redump-compliant disc image, you need specific, high-quality hardware and software:
If you are using an FPGA device (like the MiSTer or a PSIO) or an ODE (like the Fenrir or MODE), Scene rips often fail because they rely on the original disc's specific sector layout. Redump images are the gold standard for hardware emulation. First, a crucial distinction: A massive project aiming
