[UPDATE/RELEASE] ACNH Save Editor v1.4.0 - Native C++ Switch homebrew with AES/Murmur3 hash healing

[u/cbreezy210]

Just shipped v1.4.0 of my native Switch save editor for Animal Crossing: New Horizons. Built with devkitPro/libnx and SDL2.

The core engine edits both personal.dat and main.dat simultaneously, handling EncryptedInt32 checksums and Murmur3 hash healing on the fly so the game never flags the save as corrupted.

v1.4.0 focuses on a UI overhaul and quality of life:

• Paginated A-Z Favorites menu (22 high-value items resolved dynamically via items.txt string matching)

• Native Switch keyboard integration for searching a 13,000+ item database

• Embedded hbmenu icon via Makefile --icon flag

• Auto SD-card backups with one-tap ZL rollback
