CHD, which stands for "Compressed Hunks of Data," is a file format originally developed by the MAME (Multiple Arcade Machine Emulator) project to compress the hard drive images of arcade games. Since then, its use has been expanded to cover many disc-based systems, including the PSP. At its core, a PSP CHD file is a compressed version of a PSP ISO (the raw, uncompressed disc image). It uses like LZMA and Zstandard, which can significantly shrink file sizes without losing a single bit of game data.

As SSD prices drop, you might ask: "Why compress at all?" Because the "better" experience is not just about space—it's about (one file per game), integrity (built-in checksums), and speed (less I/O bottleneck).
Some compression formats achieve smaller file sizes by degrading the quality of the game—such as compressing video cutscenes or lowering audio bitrates (often seen in .PBP or heavily modified CSO files). CHD, which stands for "Compressed Hunks of Data,"

CHD solves this. It organizes data into "hunks," allowing the PPSSPP emulator to read and decompress small packets of data instantly. Playing a PSP game in CHD format gives you the exact same smooth, lag-free performance as a raw ISO, but at a fraction of the file size. 3. It is 100% Lossless
