For Dreamcast users, the CHD format has become a saving grace—and Sturmwind is a perfect case study why. : Because CHD files are smaller and optimized,

CHD is a lossless compression format specifically designed for disc images. Unlike traditional ZIP or RAR files, CHD is optimized for emulation, offering a unique set of advantages:
.
These are heavily optimized, often “downsampled” versions of a game. Because many Dreamcast games exceeded the 700MB capacity of a standard CD-R, CDI files typically compress audio or video to fit. For Sturmwind —a game originally pressed on a 1.2GB GD-ROM—early CDI releases were problematic, often removing the game’s high-quality soundtrack or FMVs.
