I am wanting to install this. For the themes to work in my Emunand. Do I need to install Menuhax to my EMU or SYS, I am unsure on this and would prefer to ask before I did it.. Thanks

There was a hotfix released for that.Use 3dsx version, 2.2 cia just leads to a black screen and frozen buttons on bottom screen

Yes.Ok, so I have the .3ds. Downloading the themes as a zip. Shall I extract the Zip into my Themes folder, then go into CHMM2 and go from there.
