ISO files contain "padding" data (empty sectors on the disc). While necessary for the physical media, this is wasteful for digital storage. CHD compresses this padding effectively but can restore it perfectly if ever needed. This ensures that the "Digital Artifact" remains pristine for future generations, unlike CSO which may alter the binary structure permanently.
Date: October 26, 2023 Subject: Evaluation of CHD (Compressed Hunks of Data) as a superior standard for PSP archiving.
The Internet Archive hosts numerous user-uploaded collections of PSP games converted to CHD format. While CHD offers lossless compression and saves storage space, current collections often suffer from inconsistent metadata, missing checksums, incomplete cover art, and poor organization. This report outlines actionable improvements to make these collections better — for preservation, emulation accuracy, and user experience.
