Originally created for MAME, the .chd (Compressed Hunks of Data) format is the gold standard for PSX compression today. It compresses the data losslessly, merges .bin and .cue files into a single file, and is natively supported by DuckStation, RetroArch (Beetle PSX and SwanStation cores), and PCSX Rearmed. How to Convert Games to CHD Using CHDMAN: Download to get the chdman.exe utility. Today, the scene has evolved
Original PlayStation game discs typically hold up to 700MB of data. However, many games use "dummy files" or padding (data added to fill the disc without actual game content). An emulator needs the game data, not the padding. This is why a 700MB BIN file can be compressed to a few hundred MBs or less.
You don't need to hunt for pre-compressed files, which can sometimes be unreliable. You can convert your own backups safely. Using CHDMAN (Recommended) chdman is a command-line tool included with MAME/MESS. Download the latest CHDMAN tool.
