The primary appeal of the CHD format lies in its remarkable compression ratios without any loss of data integrity. PS1 games were stored on CD-ROMs with a capacity of roughly 650 to 700 megabytes, yet many titles only utilized a fraction of that space. Traditional disc images often preserved the "empty" padding, resulting in large files that quickly consumed hard drive space. CHD uses advanced compression algorithms to strip away this redundancy, frequently reducing the footprint of a game by 30% to 60% compared to a standard BIN/CUE set. For collectors maintaining hundreds of titles, this efficiency translates into hundreds of gigabytes of saved storage.
Warning: This will create much larger files. You will need the matching .cue sheet. You can generate a .cue automatically using a tool like CUE Maker or extract it specifically using chdman extractcd (different command). epsxe chd files
CHD is a lossless disk image compression format originally developed for MAME (arcade emulation). It compresses disc-based games (bin/cue, iso, ccd, etc.) significantly—often saving 30–50% space—while keeping all subchannel data intact. ePSXe, one of the oldest and most popular PS1 emulators, does not natively support CHD files.

If you are a fan of PlayStation 1 emulation, you have likely heard the gospel of files. For years, the standard for PS1 emulation was the .bin/.cue pair or the single .iso file. While functional, these formats are relics of the 90s—inefficient, bulky, and prone to organizational headaches. CHD uses advanced compression algorithms to strip away
