A) ChoiDujourNX is not an .NSP file and therefore you do not install it; you run it the same way you would any other homebrew applicationthat part confuses me, do i just copy the atmosphere folder and install the nsp? if so i cant figure out what to do next, the app still crashes.
B) If you don't know how to configure Atmosphere to load ChoiDujourNX, just use the latest ReiNX instead to load it as it has the proper permissions enabled by default
