This is where 1G1R enters the chat. "One Game, One Rom" is a filter logic applied to massive datasets. It acts as a curator, stripping away the redundancy of regional duplicates to present a playable, distinct library.

What (Windows, macOS, Linux) are you running to process the files?
Ensure your Redump set is up to date, so you are filtering for the most recent revision of a game.
A complete, unfiltered global Redump set for the PlayStation requires multiple terabytes of data. By filtering out duplicate regions and minor revision clones, you can easily reduce the library size by 40% to 60% without losing a single unique video game. 2. Eliminating Frontend Clutter

For the Sony PlayStation—a console with over 7,900 licensed discs—the 1G1R Redump set represents the perfect balance between a hoarder's obsession and a player's practicality. It is the Linux ISO of retro gaming: lean, verified, and eternal.
A community-driven project that creates verified, perfect disc dumps (ISO/bin+cue) with error-checking CRCs. For PlayStation, Redump preserves the exact data from original discs, including copy protection, audio tracks, and subchannel data.
The philosophy of 1G1R is utilitarian. It prioritizes the experience of the player over the completeness of the archivist. In a 1G1R set, a tool (such as ROMVault or ClrMamePro) looks at the database of thousands of PlayStation discs and selects a single "winner" for each title.
