Before CHDMAN can compress the data, the files must be in their unzipped, native disc states (such as .bin/.cue , .iso , or .gdi ). Select all the ZIP files in your ROM folder.

Extracts the contents using 7-Zip (ensure your 7-Zip installation path matches the path in line 4 of the script). Automatically detects the .cue , .iso , or .gdi file.
