The DSi sends a list of owned titles to the 3DS. The 3DS then seems to query the shop server via SOAP to check which titles may be transferred, it then replies to the DSi with a list of titles(of the titles which were sent to it) that can be transferred. When the user selects which title to transfer, DSi sends the banner of that title to the 3DS and many frames later the titleID. | The DSi sends a list of owned titles to the 3DS.
