Saviine Wii U

A homebrew application to dump and inject savegames of any title over network to a PC application (experimental).

Installation

Copy the wiiu folder to the root of the SD card.

Notes:

The latest version exclusively runs with the Homebrew Launcher.
Make sure you already have a save of the game on you console before trying to dump/inject them.
Always backup your savedata before initiating any dumping to prevent data loss. The developer is not responsible for lost data.
Confirm that your game version matches the version used for injecting saves. e.g. injecting PAL saves into NTSC one is untested.

Super Smash Bros for Wii U specific note:

The common data is too large to inject at once, and data may be flushed at some time, making automatic restoration impossible. Make sure to keep a backup. This caution may apply to other games as well.

Wii U save folders:

The Wii U has multiple save folders: one for shared account information (common) and one for each account (e.g. 8000000a).
Currently, only dumping the common folder and your own folder is possible, as not all games use the common folder.

Folder structure:

Launch Saviine from the Homebrew Launcher.

Set the Saviine server IP using directional buttons, press A to install Saviine.

If the screen displays anomalies, use up/down to correct it.

Dumping:

Note: Make sure that the saviine server in a folder with a short path e.g. D:/saviine/
Open dump.bat or start saviine_server.exe on the PC with the argument "dump."
Launch a game; a dialog will appear to select user and/or common data for dumping.
Data will be dumped to saviine_root/dump/[game_title_id]/80000000x (user data) and/or saviine_root/dump/[game_title_id]/common (common).
Close the game and repeat the process for other games.

Injecting (experimental):

Note: Exist data will be gone after the injection. Please make sure to backup your saves before trying to inject something.
Open inject.bat or start saviine_server.exe on the PC with the argument "inject."
Place save data in saviine_root/inject folder, organized by game title id (e.g., saviine_root\inject\00050000-1010ED00).
Launch a game; a dialog will appear to select the profile to inject and whether to inject common files.
Two options for the common folder:
- Inject: Adds data into the existing common folder, overwriting existing files.
- Clean and Inject: Deletes existing files in the common folder before injecting new ones.
In case of errors during injection, the Wii tries to restore old data, but backups are advised.
