CHD (Compressed Hunks of Data) is a lossless compression format originally developed for MAME (which in turn originally stood for Multiple Arcade Machine Emulator), for the hard-drive contents of certain arcade machines. It has since been used in several other emulators as a means of storing CD-ROM game data. For CD-based games, it compresses the contents of a disc image (e.g. .cue + .bin files) to a single .chd file.[2]
Examples
Create a chd from cue file (bin file must also be accessible):
chdman createcd -i example.cue -o example.chd
