Excellent support across PC, Android, and standalone builds.

CHD (recommended) For Sega Saturn, you should be using CHD files. Joey's Retro Handhelds

In this guide, we will explain what CHD files are, why they are better than BIN/CUE or ISO, how to use them on modern emulators and handhelds (like the Steam Deck or Retroid Pocket), and how to convert your existing library.

For (the real timesaver), create a .bat file with this script: sega saturn roms chd

CHD is a lossless format. If you ever need to use an older emulator or a physical modchip hardware setup (like the Satiator or Fenrir ODE) that specifically requires BIN/CUE, you can reverse the process. Simply create a batch file using the command chdman extractcd -i "%%i" -o "%%~ni.cue" -ob "%%~ni.bin" to unpack your files with zero data degradation.

The CHD format, originally developed by Aaron Giles for the MAME (Multiple Arcade Machine Emulator) project, was designed for arcade hard drives and laserdiscs, but it proved perfect for optical media like the Saturn’s CDs. CHD employs a combination of lossless compression (zlib or LZMA) and, crucially, . The format divides a disc image into small, fixed-size “hunks” and compresses each independently. This offers two massive advantages:

If you are using RetroArch , simply drop the .chd files into your 'Saturn' folder. RetroArch will automatically recognize them via the "Beetle Saturn" core without needing a separate CUE file. Excellent support across PC, Android, and standalone builds

Note : Some emulators require the CHD to be placed in a folder with a specific structure or an accompanying .cue file for multi-disc swapping.

Enter —the gold standard for retro gaming storage. In this post, we’ll dive into why CHD is the best format for your Saturn collection and how to make the switch. Why Switch to CHD?

For anyone curating a Saturn library, the move from BIN/CUE to CHD offers several compelling advantages. For (the real timesaver), create a

A single Sega Saturn game can sometimes consist of dozens of separate .bin tracks (one for data, and dozens for Red Book audio). CHD collapses all of these into one single .chd file , completely eliminating directory clutter.

For multi-disc games like Enemy Zero or Deep Fear , convert each disc into its own independent CHD file (e.g., Game (Disc 1).chd , Game (Disc 2).chd ). You can manage disc swapping easily within RetroArch using an .m3u playlist file.

Sega Saturn games are notoriously region-locked. When compressing your games, keep European (PAL), American (NTSC-U), and Japanese (NTSC-J) files organized in subfolders to make setting up emulator region settings easier later on.
