ACNH Save Editor vs PKHeX

ACNH Save Editor is a free, open-source Nintendo Switch homebrew application for editing Animal Crossing: New Horizons saves. It changes Wallet Bells, Bank Bells, Nook Miles, house-loan values, and pocket items across the game’s save files. A searchable database contains more than 13,000 items, while Favorites presents 22 curated entries in a paginated alphabetical list. Pocket tools can clear a selected slot and save or load up to five loadouts on the SD card. Before each write, the editor makes a byte-verified SD-card backup; ZL can roll back to the latest backup. It recalculates hashes and checksums and repairs hashes after modifications. Edits are capped at in-game maximums and operate offline on-console. Version 1.4.0 edits only the primary resident, Villager0. Installation requires Atmosphère custom firmware and launching through Title Override or a forwarder, with SD-card and DBI/MTP packages provided.
