# ICON is the filename of the icon (.jpg), relative to the project folder.
#   If not set, it attempts to use one of the following (in this order):
#     - <Project name>.jpg
#     - icon.jpg

#   If a JSON file is provided or autodetected, an ExeFS PFS0 (.nsp) is built instead
#   of a homebrew executable (.nro). This is intended to be used for sysmodules.
#   NACP building is skipped as well.
