This software program is vastly outdated. Use ctrtool as a substitute!

3DSExplorer can discover numerous 3DS-related information and examine the knowledge as described on 3DBrew.





Wants .NET Framework 4.0, you may get it right here.

Be aware: If you wish to set up this program for Mac, Linux, or FreeBSD, you must set up the newest model of Wine with Wine Mono.

It runs nicely on Linux, however I have not examined it on Mac OS X.


  • CTR Cartridge Picture information (CCI/CSU) (NCSD)
  • CTR eXecutable Picture information (CXI) (NCCH)
  • CTR File Archives (CFA) (NCCH)
  • CTR Importable Archives (CIA)

  • Movies to 2D/3D MJPG AVI information for the 3DS (can obtain straight from YouTube)

A number of the file codecs will be saved with changed contents.

Choice for studying 3DS/CCI/CSU information from ZIP/7Z information




Simply compress your 3DS/CCI/CSU file right into a 7Z or ZIP (with another file you need like NFO file)

Then you possibly can open it from 3DSExplorer. However bear in mind that solely the primary CXI will likely be loaded and saving capabilities is not going to be out there.

(3DSExplorer appears for the primary file with the correct extension and reads the primary 0x5000 bytes)

Upcoming options




for v1.6

  • Extracting binaries from CIA like ctrtool does.
