To support custom makepkg build directories, it would be nice to add ns-usbloader and ns-usbloader.desktop as sources. In order to build this package, I also had to remove the ../ from the install commands.
I am not quite sure how to use them together since I have been out of the homebrew scene for a long time. I am on the newest versions of each. When I scroll to the goldleaf menu on usbloader, the USB tab is greyed out like it doesn't see it. When I got to explore content > remote pc (via USB), Goldleaf hangs and doesn't show more drives.
