: There's a common misconception that compressed files lead to slower game performance. However, for the Wii U format, a .wux file performs in Cemu on par with, or in some cases better than, a full .wud image. This is because the compression removes "garbage data" that can slow down loading. Many users find performance to be nearly identical to a fully decrypted game.
Here is a typical workflow for modding when you have a BOTW .wux file:
