In a raw, unprocessed ROM collection, you might find dozens of copies of the same game. For example, a full set for a console could include the USA version, the European version, the Japanese version, a budget re-release (a “Platinum” or “Greatest Hits” variant), a later software revision, and sometimes even multiple revisions of the same regional release. While having all of these variations is great for historical preservation, it is not very practical for the average user or for a clean archival system.
For users who prefer a plug-and-play solution, pre-assembled 1G1R Redump PlayStation sets are available. Notable examples include the collections on the Internet Archive. These sets are meticulously curated using the described techniques and are divided into USA, Japan, and Europe collections, allowing users to build a custom regional library or download the complete 1.05 TB set for the ultimate archival collection.

Redump.org represents the antithesis of this anarchy. It is a disc preservation database dedicated to building accurate dumps (ISOs) of optical media. The name itself is literal: if a dump is found to be inaccurate, it must be "re-dumped." For the Sony PlayStation—a system that relied on the fragile, degradable medium of CD-ROMs—Redump is the gold standard of truth. It ensures that the ISO is a bit-perfect replica of the original master, including the correct "wobble" groove and subchannel data. : A ROM manager that uses the DAT
