ACNH Save Editor
ACNH Save Editor is a free, open-source homebrew save editor for Animal Crossing: New Horizons on Nintendo Switch.
What ACNH Save Editor is
ACNH Save Editor is a free, open-source homebrew save editor for Animal Crossing: New Horizons on Nintendo Switch. It can change wallet and bank Bells, Nook Miles, house loans, and pocket items. A searchable item database contains more than 13,000 entries, and a Favorites menu offers 22 curated items. Players can choose and clear pocket slots and save or load up to five pocket loadouts on the SD card. Before writing changes, the app creates a byte-verified SD-card backup, with ZL rollback to the most recent backup. It recalculates save checksums and hashes after edits, and the maker describes automatic repair for hashes affected by older versions. Changes are limited to in-game maximums and values and items present in the base game. Version 1.4.0 edits only the primary resident, Villager0; map editing and design-pattern preview are unavailable. The app runs offline on-console, but modifying saves still carries risk. It requires Atmosphère custom firmware and must launch through Title Override or a forwarder, rather than Album/Applet mode.

Who it suits
This is for Animal Crossing: New Horizons players with a Nintendo Switch running Atmosphère custom firmware who want to edit save data. It is not suited to players who need multi-resident or map editing.
Verdict
ACNH Save Editor offers focused save changes and backup rollback for Switch users who meet its custom-firmware requirements. Its current resident limit and unavailable editing features are important constraints to weigh first.
