PUSH-UPDATE (v1.4): Favorites Overhaul & UI Polish — Paginated A–Z Favorites, 22-Item Roster & Embedded Homebrew Icon! v1.4.0 is out now! See my reply below for the new download link.

### [RELEASE] ACNH Save Editor - Native Switch Homebrew Save Editor

Hey everyone! I'm excited to share the latest update of **ACNH Save Editor**, a native Nintendo Switch homebrew save editor for *Animal Crossing: New Horizons*.

Unlike older tools, this runs entirely on your console—meaning **no PC is needed** to modify your game! This started as an educational project built with devkitPro/libnx.

**🔗 UPDATED GitHub Repository & Download:** https://github.com/cbreezy210/acnh-save-editor/releases/tag/v1.4.0

---

### ✨ Features

* **Direct NAND Access:** Reads and writes the live save data directly from and to your console's NAND. No manual dumping required!

* **Economy Editing:** Edits your Wallet, Bank Bells, Nook Miles, and House Loan directly (handles encrypted ints and heals Murmur3 hashes automatically).

* **Pocket Item Injector:** Features a full English item-name lookup using the `items.txt` database from NHSE. Search 13,000+ items by name with the native keyboard.

* **Paginated A–Z Favorites:** Press X to browse 22 curated items (NMTs, bell bag, voucher, 99k bells, gold roses, cherry-blossom petal, pearl, gold bars, all 6 golden tools, both crowns) sorted alphabetically with smooth page scrolling.

* **Embedded Homebrew Icon:** The leaf icon now shows in your Homebrew Menu instead of the default placeholder.

* **Safety First:** Performs an automatic SD card backup before every single NAND write to prevent data loss. One-tap ZL rollback to restore.

---

### 💾 How to Install & Run

1. Download `acnh_editor_v1.4.0.zip` from the link above.
2. Extract the `switch` folder to the root of your SD card (creates `sdmc:/switch/acnh_editor/`).
3. On your Switch Home Menu, highlight *Animal Crossing: New Horizons*, press **X**, and select **Close** to ensure the game isn't running.
4. Launch a title while holding **R** to enter the Homebrew Menu with full RAM access.
5. Select **ACNH Save Editor** and enjoy!

*Disclaimer: Even with the automatic SD backup feature, it is always good practice to keep an extra copy of your saves safe. Please report any bugs directly on the GitHub Issues page!*

Hey everyone! A big update to my native Nintendo Switch homebrew save editor for Animal Crossing: New Horizons. As a reminder, this runs entirely on your console—meaning no PC is needed to modify your game! It started as an educational project built with devkitPro/libnx, and v1.1 gives it a proper graphical interface.

**🔗 UPDATED GitHub Repository & Download:** https://github.com/cbreezy210/acnh-save-editor/releases/tag/v1.4.0

What's New in v1.1

Full Graphical UI: The text console is gone—the editor now runs on a clean SDL2 interface with highlight-bar navigation.

On-Screen Branding & Text: Renders the app icon and crisp rounded text using a bundled font.

Same Proven Engine: Every v1.0 save-editing feature works exactly the same, now wearing a suit.

Features

Direct NAND Access: Reads and writes the live save data directly from and to your console's NAND. No manual dumping required!

Economy Editing: Edits your Wallet and Bank Bells directly (handles encrypted ints and heals Murmur3 hashes automatically).

Pocket Item Injector: Features a full English item-name lookup using the items.txt database from NHSE.

Safety First: Performs an automatic SD card backup before every single NAND write to prevent data loss.

How to Install & Run

Download acnh_editor_v1.1.zip from the Releases page and extract it to the root of your SD card. It creates sdmc:/switch/acnh_editor/ with the .nro, items.txt, font.ttf and icon.png (the graphical version needs all four).

On your Switch Home Menu, highlight Animal Crossing: New Horizons, press X, and select Close to ensure the game isn't running.

Launch a title while holding R to enter the Homebrew Menu with full RAM access.

Select ACNH Save Editor and enjoy!

Controls: Up/Dn select · < > step · L/R big steps · A backup+save · + exit

Disclaimer: Even with the automatic SD backup feature, it is always good practice to keep an extra copy of your saves safe. Please report any bugs directly on the GitHub Issues page!

@everyone v1.2.0 is out now! Huge update adding Loan, Miles, Loadouts, and a Restore button. See the GitHub link below.

The native Switch Save Editor is back with v1.2!

This update is massive. We've moved beyond simple item injection into full dual-file save management.

**✨ New in v1.2.0:**
* **🏡 House Loan:** Edit `main.dat` to zero out Tom Nook's debt instantly.
* **✈️ Nook Miles:** Max out your miles balance directly from the console.
* **🎨 Favorites Menu:** Press **X** for 1-tap injection of NMTs, Star Fragments, Gold Tools, and Nuggets. Includes a visual Slot Picker.
* **💾 Pocket Loadouts:** Press **Y** to save/load 5 named setups (Mining, Fishing, Terraforming) to your SD card.
* **🛡️ Backup Restore:** Press **ZL** to instantly rollback your save to the last state if you make a mistake.

It runs 100% natively on the Switch, handles all the encryption/hashing automatically, and backs up your files before every single write.

**🔗 UPDATED GitHub Repository & Download:** https://github.com/cbreezy210/acnh-save-editor/releases/tag/v1.4.0

Let me know what features you want to see in v1.3!

v1.3.0 is LIVE! 🚀

The native Switch Save Editor is back with a massive quality-of-life update!

We've completely overhauled the item selection process and polished the UI to make it feel like a premium, professional tool.

✨ New in v1.3.0:

🔍 Native Item Search: Press + to open the Switch keyboard and search the entire 13,000+ item database by name. No more guessing hex codes!

📐 Expanded UI Panel: Increased the interface size (900x480) to perfectly contain all text and eliminate overflow.

⚡ Instant Lookups: Optimized the items.txt database loading for zero-lag name rendering.

🚪 Graceful Exit: Added a dedicated "Quit App" option to the main menu.

It still runs 100% natively on the Switch, handles all AES/Murmur3 encryption and hashing automatically, and backs up your files before every single write.

**🔗 UPDATED GitHub Repository & Download:** https://github.com/cbreezy210/acnh-save-editor/releases/tag/v1.4.0

Let me know what features you want to see in v1.4 (House Storage and Turnip Prices are on the roadmap)!
