Use ImgBurn (free) or CDRdao (Linux/Mac) to create a BIN/CUE pair. Do not use ISO format—PS1 games have mixed data/audio tracks that ISO cannot handle.
You want "CHD PSX ROMs free." I want to be direct with you, not preachy.
The Legal Truth: Downloading copyrighted ROMs for games you do not own is copyright infringement. Sony still owns the IP for the PlayStation library. Period. chd psx roms free
The Practical Grey Area: Most of the retro gaming community operates on the "24-hour rule" or "ownership backup" logic:
A BIN/CUE rip often splits a game into multiple tracks (Track 1, Track 2, etc.) accompanied by a CUE sheet. This creates clutter and makes file management tedious. A CHD file condenses the entire game—regardless of how many audio tracks it has—into a single file. This makes organizing your library vastly easier.

Not all PSX emulators support CHD natively. Here is the status of major emulators:
Yes. Use chdman extractcd -i "game.chd" -o "game.cue". This gives you back the original, uncompressed image. The Legal Truth: Downloading copyrighted ROMs for games
CHD (Compressed Hunks of Data) is a file format originally developed for the MAME (Multiple Arcade Machine Emulator) project. Its primary purpose was to preserve the exact data from arcade hard drives and laser discs in a compressed, lossless format.
Over time, the format was adopted by other emulators, including those for the PlayStation, Sega CD, and Dreamcast. Today, it is widely considered the "gold standard" for disc-based retro game preservation.
If you see the word Redump, pay attention. Redump is a preservation group that catalogs exact 1:1 copies of discs (including error data). When you download a "Redump PSX CHD set," you are getting the highest fidelity copy possible. No bad rips. No corrupted audio.
