A file is a DiscJuggler image format. It is compressed and downsampled to fit onto a standard 700MB CD-R.

While manual GDI to CDI conversion is complex and often requires modifying game code, many users now prefer CHD (Compressed Hunks of Data) If the hashes match, the file is identical

The Sega Dreamcast remains a beloved console for retro gaming enthusiasts, but managing its game library in the modern era comes with unique technical challenges.
