1G1R implies "One Game." But how do you handle Final Fantasy VIII (4 discs)?
Build a 1G1R set if:
Keep the full Redump set if:
For 99% of Sony PlayStation fans, the 1G1R approach is perfection. It respects the work Redump does to preserve revisions while acknowledging that playing the game is the final goal. You get one clean CHD file per game title, curated by region and revision, ready to load into DuckStation or RetroArch. 1g1r redump sony playstation
The Golden Rule: Document your choices. If you choose the USA version of Metal Gear Solid over the Japanese "Integral" version (which has first-person mode), write a readme file. The next archivist will thank you.
Now go rebuild your set, and enjoy the PlayStation library the way it was meant to be enjoyed: completely, without clutter.
Ultimately, the distinction between a raw Redump set and a 1G1R Redump set is the distinction between an Archive and a Library. 1G1R implies "One Game
The Archive (The Redump Database) seeks to preserve everything—every misprint, every revision, every localized German voice track. It is concerned with the raw history of the medium. It is the vault where the data lives, safe from disc rot and obscurity.
The Library (The 1G1R Set) seeks to organize that data for consumption. It values accessibility and sanity over total completeness. It says, "Here is the PlayStation experience, stripped of noise, ready to be played."
In the modern era of emulation, where a Raspberry Pi or a handheld device can emulate the PlayStation with near-perfect accuracy, the 1G1R Redump set has become the gold standard for the end-user. It is a testament to the maturity of the emulation scene: we are no longer scrambling to find any copy of a game; we are now debating the nuance of which specific copy deserves a spot in our digital library. It is a luxury born of decades of preservation work, ensuring that the legacy of the gray box remains not just intact, but playable. Keep the full Redump set if:
The PSX has hundreds of Japan-only games (Tobal 2, Racing Lagoon). A strict 1G1R set keeps these because no alternative region exists. But what about a game released in EU and JP, but not USA? Most 1G1R rules say: keep the English-friendly version (EU) over the Japanese version.
The 1G1R (One Game, One ROM) principle was born out of frustration. Standard "full sets" (e.g., a complete TOSEC or No-Intro pack) contain every single known variant of every game. For the PlayStation, that means:
A full Redump set for Sony PlayStation is over 6,000+ disc images (including multi-disc games counted separately). A 1G1R set reduces this to roughly 1,500–2,000 unique titles. It uses a prioritization system (usually: USA > Europe > Japan) to keep only the best, most playable version of each game.
