This exploit was pretty big, it used a free-to-play digital game from the eShop called "Ironfall Invasion" to gain access to homebrew. If you have versions 1.0 or 1.1 of Ironfall (the versions released before it was temporarily pulled September 2015), you can use this exploit. This method works on the latest system version, and all other 9.X versions. You do need to get homebrew at least once before to install.

 

 

 

 

 

 

 

 

 

 

 

To install it, load up any other form of homebrew, open the installer app, choose your firmware, and install. Now whenever you start Ironfall Invasion, you can start the savefile named "ironhax" to load homebrew.
