Ill try my best... Im useless at tutorial's but this should help you get it done.
Step 1. Getting the correct folder structure to inject from your WiiU.
To inject a Loadiine save to the WiiU internal storage for use with a disc/eshop game, First dump a save with
SAVIINE to get the correct folder structure & Game ID's/Profile ID'S. Once you've dumped the save game you want to replace & have the correct folder structure & ID'S with saviine, Copy the unique Game ID folder
00050000-xxxxxxxx from
saviine_root/dump/ & paste/move it to
saviine_root/inject/. Open the
00050000-xxxxxxxx folder inside
saviine_root/inject/ & there should be 2 folders,
800000xx &
common. <<Keep this window/folder open, We'll need to replace files in these folders later<<
Step 2. Replacing a normal/nand save with a Loadiine save.
Download a save from this thread
, Extract it & you should get 2 folders,
U &
C (These 2 folder may also be inside a
00050000-xxxxxxxx). Copy all the files from inside of the
U folder that you just downloaded, & paste them in to your
800000xx folder that we did in the first step >>
saviine_root/inject/00050000-xxxxxxxx/800000xx/. Now do the same for the
C folder, Copy all of the files from inside of the
C folder & paste them in the
common folder >>
saviine_root/inject/00050000-xxxxxxxx/common/. Once all of the files inside
U &
C have been copied to
800000xx & common, Go ahead & inject the save back to your WiiU with saviine.
As for using a WiiU internal save with Loadiine, Reverse step 2 & copy to SD card. Pretty simple once you've done it a few times.
