Why use it for Saturn?
Sega Saturn games often used subchannel data for anti-piracy. Some modern emulators (like Mednafen and Beetle Saturn) require 100% accurate subchannel reproduction. CHD natively stores this. BIN/CUE typically loses it unless you use a .sub file alongside the cue sheet. | Game Title | BIN/CUE Size | CHD
