A group of developers have released a 3DS ram dumping tool called 3DS Toolkit, here is some information about the application:
This project was originally titled “ROP Loader” but was changed due to functionality intended to be added at a later time.
The “DS Profile” exploit is/was(depending on when you are reading this) a well known, but not often performed exploit for the Nintendo 3DS. This exploit involved setting a value too high for the length of a string which caused too much to be read on the stack.
If you would like to read more about the exploit in particular, refer to the “Details” tab. Otherwise,source code and binary downloads for the ROP-Loader are available below.
