Dreamcast CDI Collection — Short Report

Overview

• 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").

• Complete library sets – A large folder containing CDI files for hundreds of Dreamcast games (US, EU, JP).
• Genre/curated collections – E.g., “Best Fighting Games CDI set” or “All Shmups CDI Collection.”
• Homebrew/Indie collections – Unofficial games, demos, emulators, and ports.

• Personal backups: 17 U.S.C. § 117 allows archival copies of software you own. Creating a CDI from your own GD-ROM using a compatible drive (e.g., certain Plextor or LG models) may be legal, but breaking encryption is often prohibited.
• Abandonware: Copyright persists even if a game is out of print. Sega still holds rights to Dreamcast IP, and companies like Capcom re-release games commercially.
• Homebrew & PD: Entirely legal. Collections focusing on open-source emulators and public-domain ROMs (e.g., DreamInducer discs) are non-infringing.
