You can convert your own BIN/CUE files to CHD using chdman (part of MAME).
A standard "1G1R" (One Game, One ROM) set filters out duplicates, keeping only the best version of each title per region. A truly complete world archive contains thousands of titles, accounting for regional variants, revisions, and demos. Technical Specifications and Storage Requirements
Here’s where many newcomers face reality. A full PSX ROM set is massive .
Use an XStation ODE (Optical Drive Emulator) to play your full set off an SD card on a real PlayStation. psx full rom set
You will need a dedicated external SSD or a high-capacity microSD card (e.g., 1TB) to hold the entire library. Best Emulators to Use with a PSX Set
The set is the most popular starting point. However, the combined international set exceeds 1 Terabyte, requiring a sizable external hard drive for storage.

Developed by the MAME team, CHD is the gold standard for modern PSX archiving. It compresses optical disc images losslessly. Converting a BIN/CUE collection to CHD can reduce the total file size by 30% to 50% without losing a single byte of data or audio quality. Most modern emulators support CHD natively.
Compresses files by 30-50% losslessly; merges .BIN and .CUE into a single, clean file. Cons: Requires modern emulators (RetroArch, DuckStation). 3. PBP (The Best for Portability)
The most ethical way to build a personal digital library is to "rip" your own physical PS1 discs using a standard PC optical drive and software like ImgBurn. You will need a dedicated external SSD or
Unlike a cartridge-based console (like the SNES), the PlayStation requires a file to function. The BIOS is the console's onboard operating system. Without the correct .bin BIOS file, your emulator will sit at a black screen. These files are still copyrighted by Sony, so you are expected to dump the BIOS from your own console (or find a repository for the specific versions if you are in the preservation space). There are specific BIOS versions for different console models (SCPH-1001, SCPH-5501, SCPH-7001, etc.), though most emulators handle the common models fine.
Use automated scrapers to pull box art, game descriptions, and release years based on the database IDs inside your ROM set. This transforms a dry list of file names into an interactive digital museum.
