3DS Emulator

There is already a 3DS emulator, the Citra (citra-emu.org‎).

You will need to have installed the Visual C++ Redistributable for Visual Studio 2017. Download the 64-bit version.

To play at Citra it is necessary to decrypt the game. Use the Batch CIA 3DS Decryptor. Download the tool, unzip and you will have a folder with a Batch CIA 3DS Decryptor.bat file. Just copy the .3ds or .cia game file into this folder and run the .bat file. It will create a decrypted version of the game. This tool uses a lot of memory, so it is recommended to close the programs on your computer before running.
