make a folder of the game you have.
*gamename* [xxxxxx]
the part in bold you must get the proper title id for your game and type it inside the brackets it's 6 characters long.(google)
folder should be structured like:
*gamename*[xxxxxx]
-code
-content
-meta ( get it elsewhere jnustool if the game has an update)
code content and meta go inside the game name folder.
