  • 1. Launching the Kernel exploit for loadiine.
  • 2. Launching loadiine.

The Kernel exploit and Loadiine can be found on public servers, for example:

If you want to host loadiine on your own local server, or to get more informations how to use Loadiine, you can refer to the release thread.

X - Install Loadiine with the log server enabled. You need to set your computer's IP on the install screen.


A - Auto-boot selected game using Disc mode.
X - Auto-boot selected game using MiiMaker mode.
Y - Mount selected game and exit to WiiU System Menu (No auto-boot). Launch Disc or Miimaker manually to boot the game.
Home - Exit to miimaker with no game mounted.

To load another game

1. Exit your current game.
2. Launch MiiMaker.

Game folder structure

The games are located on FAT32 SD card, in extracted file system format (not in .wud or .wux file format).

SD:\wiiu\games\<GAME TITLE HERE>\

In the created game folder, copy the code, content and meta folders. Example:

SD:\wiiu\games\Yoshi's Woolly World\code\
SD:\wiiu\games\Yoshi's Woolly World\content\
SD:\wiiu\games\Yoshi's Woolly World\meta\

The savegames will be created automatically by Loadiine in sd:\wiiu\saves\ folder.

To dump the content folder, you can use TCPGecko or a modified version of Saviine.

To dump the rpx and rpl files from the code folder, you can use Dumpiine.

To get the game's values needed for app.xml and cos.xml, you can use Loadiine XML Dumper.
