Before you start building your collection, you must understand what "CDI" actually implies for game quality.
To shrink 1GB GD-ROMs down to 700MB, early rippers aggressively compressed assets. They downsampled glorious stereo soundtracks to mono audio, downscaled cinematic video files (SFD) into heavily pixelated videos, or completely removed background music.
If you are burning, look for that reduce seek times, preventing the infamous "Dreamcast stutter" in open-world games. Building Your Collection: What to Look For If you share with third parties
