How to Convert DUC to SAV

Video game emulators are programs designed to mimic the hardware used to play games for the Game Boy Advance, Nintendo DS and other video game consoles. When the player saves his progress using an emulator, the program generates a "SAV" file which can be traded, shared and edited. Some programs such as Action Replay generate saves in the less common "DUC" format instead, which some emulators cannot read. Fortunately, free programs and services are available to convert DUC files to SAV files.

Skill level:
Moderately Easy


  1. 1

    Open a save game converter website such as the Shunyweb Savegames Converter or NDS and GBA Save File Converters.

  2. 2

    Click the "Choose File" button and pick your DUC file.

  3. 3

    Select the "Source Format" from the drop-down menu. The exact source may vary depending on what version of the Action Replay generated the DUC file. If you do not have this information, select "Action Replay MAX" and try the other options if it does not work.

  4. 4

    Choose "Raw Save" on the "Target Format" menu. For the Shunyweb Savegames Converter, choose "RAW Format [Autodetection]." Alternatively, if you are using a savegame editor or specialized save loading device, you may need to select the appropriate format for your hardware. If you cannot find the right format in the menu, consult your hardware's documentation.

  5. 5

    Click the "Convert" button to generate your SAV file.
