In 2026, SSD space is precious. You do not want to waste 1.2TB on Dreamcast games when you can fit the entire US library (248 games) into roughly using CHD compression.

The Sega Dreamcast was a gift from the future. Even today, in an era of 4K ray tracing and 120fps gaming, the little white console that could holds a special place in the hearts of gamers. Titles like Shenmue , Soulcalibur , Jet Set Radio , and Power Stone are timeless masterpieces. dreamcast+games+highly+compressed+better

Once verified (open the CHD in Redream to test), you can safely delete the bulky GDI/BIN sets. Extreme Compression: 7z + RVZ (For Archiving Only) If you are not planning to play the games immediately—only archive them on a cold storage drive—you can go smaller than CHD. In 2026, SSD space is precious

But there is one massive pain point:

High compression for Dreamcast works so well because algorithms like and ECM (Error Code Modeler) look at those dummy files and say, "A string of 10 million zeros? I can represent that in 4 bytes." Even today, in an era of 4K ray

The Dreamcast’s GD-ROM format was notoriously inefficient. To speed up load times, developers often used "dummy files"—gigabytes of blank zeros—to push game data to the outer edge of the disc where it could be read faster. When you rip a game to a standard .CDI or .GDI file, you are preserving all that useless padding.
