The newest hacking tools for the Nintendo 3DS! (updated 09/30/2011)
You don't need any additional hardware, you can just use the built in wifi and the included 2 gb sd card with this software. No installation necessary! Detailed readme.txt included.
Note: This will NOT brick your system, ever. If Nintendo releases a firmware update which disables the hack and the software has not been updated yet, the games simply won't work but your 3DS and your savegame will not be affected at all. New versions of the hack will be released with every firmware update asap.
