Converting CHD back to ISO/BIN is a straightforward process that restores your games to their original, uncompressed state. While CHD is the king of storage efficiency, having your files in ISO format ensures that no matter what new emulator or hardware mod comes out, your library will be ready to play.

Type the following command and press Enter: chdman extractcd -i "gamename.chd" -o "gamename.iso"

If you have dozens of games to convert, doing them one by one is impractical. You can automate the process using a simple script. For Windows (Batch Script): Open . Paste the following code into the document:
