Consolidates multi-track files (like .bin/.cue) into one tidy file.

If you fall into one of the categories above and need to extract an ISO from a CHD file, you can do so easily using the official tool created by the MAME team called . Step 1: Download chdman

The Compressed Hunks of Data (CHD) format is an incredible tool for retro gaming emulation. It dramatically shrinks raw disc data for consoles like the PlayStation 2, Sega Saturn, and Dreamcast. However, if you are moving your library back to original hardware—such as loading games onto a hard drive for an actual PS2 using Open PS2 Loader (OPL)—the console will require the standard, uncompressed ISO format.

Note: If you are converting CD-based games instead of DVDs, change extractdvd to extractcd and .iso to .cue in the script above. Click . Change the "Save as type" dropdown to All Files ( . ) . Name the file convert.bat and click Save . Double-click convert.bat to run it.

The official, gold-standard tool for CHD manipulation is (CHD Manager). It comes bundled with MAME. You can find it in the latest MAME release zip file ( mame.exe folder contains chdman.exe ).

For those who prefer the control and transparency of the command line, here is the manual method.

Which are these game files originally from?

If you manage a large library of retro game disc images for emulation, you have likely encountered (Compressed Hunks of Data) and ISO (International Organization for Standardization) files.

The chdman.exe tool is bundled automatically with any desktop download of the MAME emulator. Download the latest MAME release and extract the files to find the application. Step 2: Use the Command Prompt

If you have dozens of games to convert, processing them one by one is tedious. You can automate the process by creating a text file in your folder, pasting the following code into it, and saving it as extract.bat :

Create a new text file in your CHD folder. Name it convert_chd_to_iso.bat . Paste the following:
