note that the video tutorial is covering the first Loadiine release.
New/latest releases are now using a different path for your files on SD card.
The new path is (for me) much easier:
When you extract a game with DiscU or an Update from nintendo's servers with CDecrypt, it will generate 3 (or more) folders :
/code/ <-- contains the executable
/content/ <-- contains the game's data
/meta/ <-- contains game information, icon, etc.
/system/ <-- you don't need this one
The NEW releases of loadiine only need you to copy the 3 folders inside the folder of your choice :
sd:/wiiu/games/<folder name with the gam's title of your choice>/<Copy HERE the 3 extracted folders>
exemple:
sd:/wiiu/games/Yoshi's Woolly World/code/
sd:/wiiu/games/Yoshi's Woolly World/content/
sd:/wiiu/games/Yoshi's Woolly World/meta/
Do not care about the save folder, it will be created automatically on first launch.
