If you are a retro gaming enthusiast using emulators like RetroArch, MiSTer FPGA, or MAME, you have likely encountered files. CHDs are fantastic for saving storage space, as they compress large optical disc images (like CD-ROMs or DVD-ROMs) into a smaller, more manageable file size.

Command Syntax:

Converting a large collection of games one by one can be tedious. Batch processing is the way to go. Here's how to automate the conversion of an entire folder full of CHD files.

convert_chd() local input_file="$1" local output_file="$OUTPUT_DIR/$(basename "$input_file%.chd.iso")"
