Using a CHD file instead of traditional BIN/CUE files offers several technical advantages. First is the massive saving in storage space. CHD uses lossless compression, meaning you lose zero game data while shrinking the file size significantly. Second is simplicity. Because a CHD file consolidates the data and audio tracks into a single file, you no longer have to manage messy multi-file folders. This makes it much easier for frontend launchers like RetroArch, LaunchBox, or EmulationStation to scrape metadata and display box art.

For many, this single disc contains more character development and world-building than most full games. Second is simplicity
The beauty of the .chd extension is its widespread support. You do not need to extract the file.
