New Horizons Save Editor (NHSE) is a save editor tool for Animal Crossing: New Horizons.
It’s a useful tool, but the only drawback is that the devs only provide Windows binaries.
Here’s how to get it running on a Steam Deck (or really any Linux distro).
note: You are expected to do everything in desktop mode if you are using a Steam Deck.
Unison is a powerful utility used to synchronize files and directories between systems.
These instructions are meant for Ubuntu and your experience on other systems may differ (installation process on Linux should be the same as long as you get the correct binary).
This works with WSL as the client.
