Once you have your CHD files, organization is key. The Sega Saturn BIOS is still required (you need sega_101.bin , mpr-17933.bin , etc.), but the CHDs themselves are plug-and-play.
Sega Saturn emulation has been revolutionized by the format, which offers a high-performance, space-saving solution for the console's notoriously bulky CD-based library. The CHD Advantage for Saturn ROMs sega saturn chd roms hot
The Sega Saturn remains one of gaming’s most intriguing systems: technically ambitious, notoriously complex, and home to a library that’s part cult classic, part obscurity. For preservationists and enthusiasts wanting to experience Saturn games on modern hardware, CHD (Compressed Hunks of Data) ROMs have become a common format. But they sit at an awkward intersection of convenience, legality, and archival practice.

Thus, convenience drives the illicit market, not malice.
