CHD to ISO Converter (Batch Script)

This simple batch script converts all .chd files in the current directory to .iso format using chdman.

Features

• Converts multiple CHD files to ISO in a single run
• Fully offline and lightweight
• Ideal for converting CHDs from DVD-based games or data discs

Requirements

• Windows
• chdman (included with MAME)

Make sure chdman.exe is in the same folder as the script or added to your system PATH.

Usage

1. Download or clone this repository.
2. Place your .chd files in the same folder as the script.
3. Double-click convert_chd_to_iso.bat or run it via command prompt.

The script will generate .iso files with the same base name as each .chd.

Note

This script uses the extractraw command, which is only suitable for CHDs containing DVD or data images.
If your CHD contains a CD-ROM image (e.g., games with audio tracks like PS1), use extractcd instead.

To check CHD type:

chdman info -i yourfile.chd
