005tools is a simple command line application designed to work with devices that can transfer game saves from CTR-005 (3DS) and NTR-005 (DS/DSi) game cards to your PC. The source code is platform independent, so it can be compiled to run on any system.
It allows backing up and restoring save games for 3DS/DSi/DS game cards using a device such as the R4i Save Dongle.
