for /r %i in (*.cue) do chdman createcd -i "%i" -o "%~ni.chd" For Mac/Linux:
You’ve probably seen .bin/.cue files, maybe .pbp files for PSP emulation, and more recently, files.
Unlike zipping a .bin file (which most emulators can’t read), CHD is a compression format. PSX CHD vs. Other Formats | Format | Compression Ratio | Multi-track Audio | Emulator Support | Best for | | :--- | :--- | :--- | :--- | :--- | | .bin/.cue | None (100%) | Yes | All | Archival, but wasteful | | .pbp | High (70-80%) | Tricky | PPSSPP, some cores | PSP on-the-go | | .chd | Very High (65-85%) | Perfect | DuckStation, RetroArch, PCSX2 | The winner |
So, what is CHD, why is it suddenly everywhere, and should you convert your library? What is a CHD File? CHD stands for Compressed Hunks of Data . It was originally developed for MAME (arcade emulation) to compress large hard drive and CD-ROM images.
