Importer

The desktop app and command line that check a game, write its manifest and copy it to the SD card or the Switch.

The importer (importer/rsl_import.py and its window, rsl_import_gui.py) needs only Python 3.9+ and its standard library. It never runs game code, never unpickles anything, never changes the source folder or archive, and does not decrypt or unpack .rpa archives.

Desktop app The importer window on macOS and Windows: the Library, the Import page and the target.
Command line Report on a game, export it to an SD card or upload it to the Switch, from a terminal.
Checks and statuses What the importer looks at, the status it gives a game, the Switch performance checks, and how archives are kept safe.
Upload over FTP Send a game to the Switch over Wi-Fi with sphaira's FTP server, without taking out the SD card.
Covers and backgrounds How the importer makes a game's cover and background, and how to choose your own on the computer or on the Switch.
Non-ASCII file names Why files with Japanese or accented names are packed into an archive, and which files cannot be.
