Introduction
What is "Steganography?"
Steganography is, "the practice of concealing messages or information within other non-secret text or data."
Well, it's pretty common knowledge that the data on your game cartidge is non-secret data, however your game save is a bit of a gray zone.
Now wait, if anyone can do this, what makes it so secret?
What makes it secret is that any interceptor will be unaware of what information that they have until it's too late.
Let's take Mario Kart 7 for example.
On boot, if the game detects in invalid save file, it automatically deletes it and replaces it with the default save. This effectively hides your data from someone who's unaware that it's on the cartridge.
Additionally, MK 7 has a replays folder, which as you can guess, contains replay files, or at least what looks like replay files.
How it's done
*** FIRST AND FOREMOST, BACKUP YOUR SAVE DATA ***
*** THERE IS A FILE SIZE LIMIT.....IT IS DIFFERENT FOR EACH GAME ***
Hiding Files
1. Download svdt and put it on your SD card
Link
2. Place all files you want to put onto your cartridge onto your SD card
3. Boot into the Homebrew Launcher and start svdt.
4. Delete some files from your game cartridge. (Games with replays work well for this!)
5. Hop over to the SD card portion of svdt and copy the files you wish to save into the game cartridge. (Make sure you put them in the correct folders!)
6. Exit svdt
You have now hidden files within a game's cartridge, congratulations! Assuming you didn't delete your game save, you might just get away with having a working game at the same time!
Retrieving Files
1. Launch svdt again
2. Navigate to where the files were placed (e.g., replays folder)
3. Copy each file to SD card
OR
2. Copy the whole folder to the SD card
4. Delete the files from the game cartridge
5. Restore any data you need to from a backup (e.g. a game save.)
You have now retrieved those hidden files, congratulations!
Usefulness
You could use this to mess with friends, or in some more oppressive parts of the world, you could hide incriminating files.
I have personally tested this with Mario Kart 7 with placing files into the replays folder. The game remains none the wiser (I didn't check if it "sees" the "replay" file in the replays menu of the game, but I know it won't load it.)
