tracks (common in Saturn games with Redbook audio), CHD merges everything into a single, tidy file Instant Access
: Modern emulators like Yaba Sanshiro , Kronos , and RetroArch (via the Beetle Saturn core) natively support CHD files.
Because the data is compressed, the emulator has to decompress it on the fly. On modern PCs (even budget laptops), this processing overhead is negligible. However, on very old hardware or low-end Raspberry Pi devices, uncompressed ISOs might have a slight edge in performance, though this is rarely an issue with the Pi 4 or 5. sega saturn chd roms top

This creates clutter and increases the chance of file corruption or mismatched tracks. A CHD file bundles everything—data and audio tracks—into a single .chd file.
