Test one game fully (gameplay, audio, cutscenes). If issues, try a different release or a higher-fidelity dump.
Catalog and tag your local archive (game title, region, revision, source, checksum, notes).
discs. They are primarily used for emulators or optical drive emulators (ODEs) like CDI (DiscJuggler Image)
Optical Media Emulation (ODE): Devices such as the MODE (Mega Optical Drive Emulator) and GDEMU have varying support for CDI files, though GDI is preferred for stability.
Legacy Emulation: Older iterations of emulators like NullDC or Chankast were built specifically around CDI parsing and may perform better with these images than with GDI.
Hardware Modification: Enthusiasts looking to burn physical backups for original hardware (using the MIL-CD exploit) rely almost exclusively on CDI files, as GDI files cannot be burned to standard CD-Rs without complex conversion tools.
