Wii U Save Files Compilation (GBAtemp)

Requirements

Hacked Wii U on Firmware 5.5.4

The SaveMii Mod homebrew application requires a Wii U with custom firmware such as Mocha or Haxchi

SD Card (64B or larger recommended)

An SD card is required to install homebrew and manage save files on your Wii U console
The SD card must be formatted to FAT32

Homebrew App Store for Wii U

SaveMii Mod can easily be downloaded and installed directly to your Wii U from the Homebrew App Store
You should already have the Homebrew App Store if you followed the Mocha, Haxchi or wiiu.hacks.guide
Follow this guide if you do not have the Wii U Homebrew App Store installed

Install SaveMii Mod

Load your custom firmware patches and launch the Homebrew Launcher via your preferred method
- Mocha CFW users simply visit wiiuexploit.xyz on the Wii U Internet Browser
- Haxchi users must launch Haxchi and hold [A] while it boots to load the Homebrew Launcher
- Coldboot Haxchi users must press [Home] while it is autobooting to access the menu and select [Boot Homebrew Launcher]
Select the Homebrew App Store -> [Load]
Browse or search for SaveMii Mod (not SaveMii)
Press [A] to download and wait for the process to complete
Press [-] to return to the Homebrew Launcher
Select SaveMii Mod -> [Load]

Backup Save Files

From the SaveMii Mod menu, select [Wii U Save Management]
Select the game save file that you wish to backup
Only titles in green can be backed up. Titles in yellow are likely to be vWii / VC injects or games without an initial save file.
Select [Backup savedata]
Select an [(Empty)] slot
Set [Wii U user] to your user profile
Set [Include ‘common’ save?] to [yes]
The majority of games saves for Wii U are User specific, however some games share saves across users. Select your user profile + ‘common’ folder or [all users] depending on your game’s requirements
Press [A] to begin the backup and wait for the process to complete
Your backup will be stored in the /wiiu/backups/ folder on your SD card

Import Save Files

Wii U backups need to be placed in the /wiiu/backups/ folder to be imported with SaveMii. Wii U save folders downloaded online must be stored in a specific way to be recognised by SaveMii Mod.

Remove any hyphens (-) from the name of the /[TitleID]/ folder
Create a folder named 0 in the /wiiu/backups/[TitleID]/ folder of your save. This folder should also contain your user folder /80000001/ and possibly a /common/ folder
Move the user folder /80000001/ and the /common/ folder into the /0/ folder
Your Wii U save backup folder should now look like /wiiu/backups/[TitleID]/0/80000001/
Insert your SD card and power on your Wii U
Launch SaveMii Mod via the Homebrew Launcher
From the SaveMii Mod menu, select [Wii U Save Management]
Select the game save that you wish to import
Only titles in green can be imported. Titles in yellow are likely to be vWii / VC injects or games without an initial save file.
Select [Restore savedata]
Select slot [000 (Used)]
Set [SD user] to [80000001 (Has Save)]
Select your user profile as the [Wii U user]
Set [Include ‘common’ save?] to [yes] if there is a /common/ folder
Press [A] to begin the backup, press [A] to confirm and choose [A] or [B] to backup the pre-existing save data and wait for the process to complete
Press the [Home] button once complete and return to the Wii U System Menu
Launch your game and enjoy the imported save file
