TWLSaveTool is a 3DS homebrew app that allows you to read, write, and erase save files from NDS cartridges (just like savegame-manager!)

You must have a game in the cartridge slot or you will get an error. A small number of games are incompatible and will not work with TWLSaveTool  (WarioWare D.I.Y., Band Brothers DX, Art Academy DS, and Pokémon Typing Adventure).
