* [[3DSExplorer]] supports reading of savegames, it doesn't support reading the new encrypted savegames and maybe in the future it will support modifying (some of the modyfing code is already implemented).
* [https://github.com/wwylele/3ds-save-tool wwylele's 3ds-save-tool] supports extracting files from savegames and extdata. It properly reconstructs data from the DPFS tree and extracts files in directories hierarchy.
* [https://github.com/wwylele/3dsfuse-ex 3dsfuse-ex] similar to 3dsfuse, but supports savegame inner FS, proper DPFS handling, and automatic CMAC update. Still WIP.
