Pros: Maximum compatibility; used by the Redump preservation project.

Quantifying the exact number of PS1 games is a subject of debate among archivists, with numbers varying based on what is counted. The figures can range significantly:

Use a collage of 90s box art or a video showing a scrolling list of titles in a front-end like EmulationStation or LaunchBox. 1.5.1 , 1.2.6

The biggest question for anyone considering this endeavor is, "How much space do I need?" The answer is genuinely shocking.

It compresses BIN/CUE files losslessly, cutting file sizes by roughly 40% to 60%.

Emulators require the original system software (BIOS) to run games legally and accurately. You must place these files in your emulator's "System" directory. The most common BIOS files are: (North America) scph5500.bin (Japan) scph5502.bin (Europe) Legal and Ethical Considerations

Note: Emulators require these files to be placed in a specific "system" or "bios" directory before loading any ROM set.

The "raw" format. Every game consists of at least two files: the (data) and the

Games released outside of Sony’s official approval.

By utilizing Redump standards, efficient CHD compression, and modern emulators like DuckStation, you can curate a massive, playable archive of one of the most important consoles ever created. Just be sure to invest in a good hard drive—5 terabytes won't fill itself.

For most enthusiasts, the 1G1R set is the holy grail. This concept focuses on "One Game, One ROM." A perfect example of this approach in action is from a project update posted on August 7, 2025, for the MiSTer FPGA platform. The creator noted the set includes "USA, Europe, and Japan exclusives," "Add-ons, Bonus Discs, and Educational games," and that "All Multi Disc game discs have been combined into same folder."
