Make a nand backup with gateways launcher.DAT.
Launch decrypt9 through CN and xor your Nand.
Copy your NAND.bin and your nand.fat16.xorpad into the folder you got from the link above.
Rename NAND.bin to emuNAND.bin and drag it onto dragnanddumpforfat16.bat.
After it finished, launch decrypt.bat.
You'll get 'emuNAND.fat16.bin.out'.
Open up that file in winimage (included in eshopmover) and extract title.db from the 'dBs' folder.
Use
FunkyCIA to extract your game.
(Put your ticket.db into FunkyCia folder and run the command 'FunkyCIA.py ticket.db -type gameapp')
Put your extracted .CIA onto your sdcard and install it in emuNAND.
If something is unclear, just ask. (I was a bit in a rush here)
