    I bought a game from eshop and wanted to create a decTitleKeys.bin of it for absolutely no reason at all >_>

    Different posts say to do that, I use Decrypt9 > TItlekey Options > Titlekey Decrypt

    But when I go there, it gives me the options of either "Titlekey Decrypt (file)" or "Titlekey Decrypt (SysNAND)"..

    The posts never specify which one I should use..
    And I know the game data is actually saved on the SD card..

    I tried using the "(SysNAND)" option, and it seemed to work but part of the log says: "Decrypted 16 unique Titlekeys. Skipped 254 useless Titlekeys."
    Well, I have more than 16 games installed on my 3DS.. So is it actually including the game that I recently purchased?..

    If I am supposed to use the "(file)" option instead, which file do I select?.. And how do I make sure the titlekey for that game's update is included?..

    I found out the "Titlekey Decrypt (SysNAND)" is probably the one you need.. Every time I've used it, it has included the titlekeys that I wanted included..

    After I buy a game, I go in to FBI and go to "Titles", and let it load all the titles I have on my 3DS, then I scroll down and search for the game (or update or DLC) I just bought, and it will show you the TitleID..

    After you go to decrypt9 and select the "Titlekey Decrypt (SysNAND)" option, it will create decTitleKeys.bin in the /files9/ directory on your SD card..
    If you want to make sure that file contains the TitleID that you want it to have in it, what you can do is open that file (decTitleKeys.bin) in a hex editor on your computer, and it is really easy to spot the different titleIDs in there.. The first titleID starts at offset 0000:0018, next one is at 0000:0038, next is at 0000:0058 (just keep adding 20.....although your eyes will already see them easily any way, because pretty much all titleIDs start with 000400)..
