You will need the tool , which is part of the MAME tools suite.
Converting physical backups to ensures that high-quality, perfectly preserved versions of these games can be played on modern hardware (like the Satiator or Fenrir) or through emulation for years to come. Summary of Benefits BIN/CUE / ISO CHD (Compressed Hunks of Data) File Size Large (Original CD size) Small (Compressed 30-50%+) File Count Multiple files per game Single file per game Compatibility High (Supported by modern emulators) Compression Lossless Compression
Emulation and preservation Emulators such as Yabause, Mednafen, and libretro cores (including Beetle/Mednafen Saturn) vary in their CHD support, and successful emulation often depends on a correct dump plus an emulator that implements Saturn-specific hardware nuances. CHD’s provenance as a MAME format gives it a pedigree in preservation circles: it is designed for long-term archival with integrity checks and tooling for verification, which aligns with the goals of museums, archivists, and enthusiasts seeking to keep games playable as original hardware fails or media degrades.

Unlike standard compression formats like ZIP or RAR, emulators do not need to extract a CHD file to read it. The emulator can read the compressed data directly in real-time. This makes it an ideal format for disc-based retro consoles, especially the Sega Saturn. Why Use CHD for Sega Saturn ROMs?
The Sega Saturn is one of the most unique and revered 32-bit consoles in gaming history. However, its complex architecture and dual-disc format mean that managing a digital library of Saturn games can be a storage nightmare. Traditional disc dumps like BIN/CUE or ISO/WAV take up massive amounts of hard drive space and clutter directories with dozens of tracks per game.
Originally developed by the MAME (Multiple Arcade Machine Emulator) team, the format is a lossless compression format designed specifically for optical media and hard drive images. CHD’s provenance as a MAME format gives it
You likely have your Saturn games in either format (most common) or IMG/CCD (CloneCD format).
Converting your library to the format solves this problem. It shrinks your file sizes significantly without sacrificing game quality or performance. What is a CHD File?
CHD compression is entirely lossless. The compression tool calculates checksums to ensure that when the emulator reads the data, it receives an exact, bit-perfect replica of the original physical disc. Your game logic, graphics, and high-fidelity CD audio remain completely untouched. Compatibility: Where Do Saturn CHDs Work?
While CHD files are incredibly stable, always back up your emulator's internal memory and save state folders before migrating your ROM library to a new format.
The easiest way to get CHDMAN is to download the latest release of MAME, or look for standalone "CHDMAN helper" packages online. You only need the chdman.exe file. Step 2: Create a Batch Script
