Welcome to the wonderful world of 3DS Homebrew!

To run homebrew on your 3DS you need a method to run custom code. There are currently several public exploits available which allow running unsigned code on a 3DS system.

With version 5.0 of the program XORpads are no longer required if proper 'boot9.bin' file detected in the same folder.

Exploits

The MSET exploit

This exploit only works on 3DS System Software version 4.1.x to 4.5.x

This exploit is also used by Flashcart manufacturers to take over the 3DS's kernel.

To exploit this vulnerability, you need a working DS Mode flashcart for your 3DS and you must run an NDS Homebrew designed to alter the DS Profile settings strings. When launching the 3DS System Settings application's DS profile settings editor, it will cause the application that edits the DS profile to crash, and this crash pushes custom code into memory from within the edited profile and makes the security co-processor 'accidentally' load that code, resulting in homebrew being launched.

Spider exploit

This exploit works up to version 9.2.0 and grants kernel level access. It was used by flashcart manufacturers after the MSET exploit was patched.
