Head to the release page and download the latest released luna.zip and extract it onto your Switch's SD card.
Luna requires a save-file-template to work. either use your own save file^[1] or use the included enctemplate.zip and unzip it in SD:/config/luna/enctemplate.

When visiting an island, whether it being a dream or a friend's island, open the homebrew menu (album app) and start Luna.
It will show you the option to dump the current island and should also display their name.

Now press the Dump button and let it work for a few seconds. If everything went right, you now have a dumped island in the dump folder, which can be used by the game and tools like NHSE.

Thanks to:

• WinterMute, fincs and contributors of devkitPro and specifically devkitA64
• Yellows8 and all the mantainers of switch-examples
• kwsch and contributors of NHSE
• Ninji for their CylindricalEarth research
• Slattz for being a bad bitch and creating LibACNH
• WerWolv for handling my constant questioning

Luna is based on Atmosphère's Daybreak, Adubbz's NanoVG port to deko3d and the filehandling of J-D-K's JKSV, as well as my own arduous research on Animal Crossing: New Horizons' inner workings of visiting other people's islands.
