I kind of missed this but awhile ago shinyqquagasire made a tool that installs homebrew onto the WiiU. I haven’t found a thread for it yet, I probably should of looked harder. I had to google it in order to figure out what the hell people were talking about. 




What I am gathering is homebrew that is in the .woomy package is installed with this tool. 


How to make a .woomy package the readme mentions:



Compiling Notes

Compilation requires makefst and WUT to be installed. The generated output is a .woomy package and a woominstaller_out folder with raw FST contents.



I haven’t used this tool at all, but it seems different. I’ll try and follow up once I figure it out.
