About

### 🇺🇸 English Version

**🎮 What is DropNES?**

DropNES is a minimalist, lightweight, and pure NES/Famicom emulator built explicitly for modern web browsers. Embracing the "Bring Your Own Game" (BYOG) philosophy, it transforms your Chrome new tab into a retro gaming console instantly. 

Simply click the extension icon, drag and drop your legally owned `.nes` game files (such as amazing open-source homebrew games) into the portal, and dive right back into the golden 8-bit era. No complex setups, no intrusive ads, just pure, uninterrupted nostalgia.

✨ **Key Features**

* 🛡️ **100% Private & Offline:** Zero ads, zero micro-transactions, and zero data tracking. DropNES runs entirely locally within your browser. Your game files and save data never leave your device.
* 💾 **Instant Save States:** Powered by a robust local database (IndexedDB). Can't beat that boss? Save your progress at any exact moment and load it instantly with a single click.
* 🕹️ **Ultimate Control:** Full support for modern Gamepads (plug and play!) and fully customizable keyboard mappings. Find the muscle memory that suits you best.
* 📺 **Immersive Retro UI:** A beautifully crafted skeuomorphic design paired with optional CRT scanline filters. Every pixel is rendered to perfection for that authentic old-school TV vibe.
* 📚 **Smart Library:** Automatically remembers your recently played cartridges. Pick up right where you left off the next time you open your browser.

🚀 **How to Play?**
1. Install the DropNES extension.
2. Prepare your legally acquired `.nes` game files (We highly encourage exploring the vibrant Homebrew indie community!).
3. Click the DropNES icon, drag your ROM file into the center console, and press Start!
