SaveMii
Latest version: v1.2.0 (Apr 09, 2017)​

You need to run iosuhax/mocha cfw first in order for this homebrew to work.

This homebrew allows you to backup your Wii U and vWii savegames to the SD card and also restore them. Up to 256 backups can be made per title. Backups are stored in sd:/wiiu/backups.

This is my first time doing Wii U stuff, so please report any issues that may occur.
Tested with Super Mario 3D World, Freedom Planet, and Super Mario Galaxy 2.

This is awesome! I will be sure to try this out when I get some free time

May I suggest renaming the tool to SaveMiiU, since there already is sometching called SaveMii for the Wii. It would be better for search purposes, and well, not to create any confusion among newcomers.

 

This awesome! I don't suppose this tool will work with HaxchiFW?

 

Finally someone made something like SaveGame Manager GX for Wii U, fantastic!
After you implemented the multi user feature you could also look into Loadiine compatibility.
Switching savegames between Loadiine (SD:\wiiu\saves) and sysNAND/USB is the only reason to use Saviine for me.

A note on savegames between Loadiine and NAND:
Every user seems to have an unique ID that starts with 8000000x and the X seems to be a random number for each user. In my case it's 4 for example and I just found out by dumping a random game's save with Saviine.
So to implement Loadiine compatibility you just have to "map" those folders (as it has to be done with Saviine right now):
SD:\wiiu\saves\Game [ID6]\c
is the common folder for NAND saves
SD:\wiiu\saves\Game [ID6]\u
is the user folder (8000000x) for NAND saves

I dunno how you could let your tool figure out that x (maybe just by dumping something) but once it has it it can move saves between NAND and Loadiine folders on SD without problems I guess. Hope that helped.

 

Nice work!

 

I've been waiting for a program like this… Looking forward to trying it! Are the saves able to be moved to a different Wii U? Thanks!

 

does the app generate the "backup" folder ?

if so i feel it would be better to have this is the SD root ,it would certainly assist with appstore updates / so as to be careful not to delete the backups directory

 

Looking forward to this. Would be a better alternative than saviine.
Could i somehow backup my save, put someone else save and work ? :Ô no pc need ?

Sd clean +1

 

COOL!

 

What was the issue?
