Extract text from DUC files
To convert your DUC file to another format, you need Action Replay Code Manager or other Game software.
To convert other file formats to the "Save Game File" file type, you need software like Action Replay Code Manager or a similar tool.
The .DUC file extension is primarily associated with Action Replay DS, a cheat device for the Nintendo DS developed by Datel. These files function as proprietary containers for game save data, allowing users to backup their progress or share "powersaves" with active cheat codes. While useful on original hardware, .DUC files are notoriously problematic for modern emulation workflows. They are proprietary and generally cannot be read natively by popular emulators like DeSmuME or No$GBA, nor can they be directly loaded onto standard flashcarts like the R4. To access your save data on a PC or different hardware, you must convert the file. For emulation, the best target format is a raw SAV (Raw Save) or DSV (DeSmuME Save).
In a completely different context, a .DUC file may be a firmware or data update package for Dynon Avionics SkyView systems. In this specific industrial use case, the file is often just a renamed ZIP archive containing navigation data or system updates. Users dealing with avionics data should check if the file can be opened by simply renaming the extension to ZIP, whereas gamers must use a dedicated conversion tool.
Convert.Guru analyzes your DUC file, detects the exact format, and lets you read the text inside.
Users also converted DSV, DST, NDS, SAV, DOCX, PDF, ACTBIN, FAV and RGD files.
If you want to convert DUC file to SAV, EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP or DAT, you can use Action Replay Code Manager or similar software from the "Nintendo DS Game Save" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to DUC, try Action Replay Code Manager or another comparable tool in the "Nintendo DS Game Save" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DUC converter.
