Important Clarification: Dreamcast vs. CD-i
Let's address the elephant in the room. Is a Dreamcast CDI collection legal?
Translations:
Japanese exclusives that never saw a Western release were fan-translated and distributed as CDI files.
- Authentic Dreamcast discs use GD-ROM; some community rips convert content to standard CD-sized images (.cdi/.iso). Ensure correct image type for your target loader/emulator.
- For hardware: GDEMU and similar use raw .GDI/.BIN or specific image layouts; follow device docs.
- For emulation: use BIOS where required and match region (NTSC-J/NTSC-U/PAL) for compatibility.
- Checksums: verify images with MD5/SHA1 if provided to ensure integrity.
- File naming: include region and disc number (e.g., "Shenmue (USA) [Disc 1].cdi").
Translations & Homebrew
: CDI files often host fan-translated gems like Phantasy Star Complete or modern indie releases from Internet Archive archives.
