1 drag your .3ds rom onto "crtkeygen.exe" this will create a file called ncchinfo.bin in the same folder as your rom

2. copy the XORpad generator (launcher.dat) from the "For the 3DS SD card" folder in this download to the 3DS's SD card
   and the ncchinfo.bin that was generated in step 1, then pop the SD back in the 3DS and go to DS profile, this will generate the 
   Xor pads used to decrypt the game.(this step can be a little buggy if it stays on "opening ncchinfo.bin" for more than a few seconds
   reset the console and repeat untill it kicks into action)

3. copy your ROM and XOR pads here.(make sure you only have the single .3ds file and corresponding xorpads in the folder


4. drag the .3ds file onto unpackv3.bat
   go into the "decrypted" folder then "romfs",
   make your edits,

5. Go back to the main directory and run makerom.bat

6. If all goes well and you will be given romedited.3ds in the main folder.
(this rebuilding step will not work with all games, 
if it doesnt work, then the game just isnt compatible, wait till a better soultion is released)


   thanks to ground for the neat and tidy decryption script,and everyone involved in making the tools
