Redump (Desktop)

Redump’s methodology focuses on capturing the entire disc structure. By following the Redump dumping guides , volunteers use specific hardware (often specialized Plextor or LG drives) and software (like DIC—Disc Image Creator) to ensure every single bit is captured. Redump vs. No-Intro

: Once a disc is ripped, its hashes (MD5, SHA-1) are compared against other submissions in the Redump database. If two different people dump the same disc and get the same hash, it is considered "verified." If a user finds a different hash, it may indicate a new revision or a bad dump. Why Bit-Perfect Dumps Matter

Furthermore, if a preservationist wants to recreate a physical disc decades from now, a Redump file provides the exact structural map necessary to burn or manufacture an authentic replacement down to the individual sector. How to Explore or Contribute

Furthermore, preservation isn't just about the game's executables. It is about context . A soundtrack, a hidden CD audio track, a specific subchannel data error that triggers anti-piracy—these are artifacts of history. Redump captures all of it. They preserve the weirdness of the physical medium, not just the software.

In the early days of emulation, optical disc ripping was the Wild West. Users would grab a standard CD-ripping tool, burn an .ISO or .BIN/.CUE file, and upload it to the internet. While these files were often functional enough to boot on early emulators, they were riddled with microscopic flaws, including:

Redump’s methodology focuses on capturing the entire disc

is the world’s premier, community-driven optical disc preservation project. Founded in the mid-2000s, Redump operates not as a piracy hub, but as a meticulous data-archiving initiative dedicated to creating a flawless, bit-perfect catalog of every video game, software application, and multimedia disc ever manufactured.

Video game history is fragile. Optical media is notoriously susceptible to damage from scratches, heat, and humidity, a process often called "bit rot" or "disc rot" that can render a game unplayable. Without a reference like Redump, there is no way to know if a backup is corrupted or complete. Redump provides this vital standard, ensuring that when a game is dumped, it can be verified against a known, perfect copy.

Both groups also publish "DAT files," which are essentially text files containing all the checksum information for a given set. These DAT files are used by ROM management software (like clrmamepro) to organize and verify game collections.

Every physical optical drive reads discs with a slight physical displacement (offset). Standard rips baked these hardware discrepancies directly into the data image, altering the final cryptographic hash. No-Intro : Once a disc is ripped, its

How data is physically laid out on the disc surface.

The Redump project offers several benefits to the gaming community:

: Discs are "dumped" (copied) multiple times by different users to verify that the resulting hash (digital signature) is identical across different physical copies.
