+# TurtleSilicon 
+
+A user-friendly launcher for Turtle WoW on Apple Silicon Macs, with one-click patching of winerosetta, rosettax87 and d9vk.
+
+## Credits
+
+All credit for the core translation layer `winerosetta` goes to **LifeisAwful**. This application is merely a Fyne-based GUI wrapper to simplify the patching and launching process. [https://github.com/Lifeisawful/winerosetta](https://github.com/Lifeisawful/winerosetta) 
+
+## Features & Highlights
+
+*   **Run 32-bit DirectX9 World of Warcraft (v1.12) on Apple Silicon:** Enjoy the classic WoW experience on your modern Mac without "illegal instruction" errors.
+*   **Significant Performance Boost:**
+    *   Utilizes the `rosettax87` hack by LifeisAwful to accelerate x87 FPU instructions.
+    *   Integrates `d9vk` (a fork of DXVK for MoltenVK) by Kegworks-App, enabling DirectX9 to run much more efficiently on Apple Silicon via Vulkan and Metal.
+    *   Experience a massive FPS increase: from around 20 FPS in unoptimized environments to **up to 200 FPS** (a 10x improvement!) in many areas.
+*   **One-Click Patching:** Simplifies the setup process for both CrossOver and your Turtle WoW installation.
+
+## Build Instructions
+
+To build this application yourself, you will need:
+
+1.  **Go**: Make sure you have Go installed on your system. You can download it from [golang.org](https://golang.org/).
+2.  **Fyne**: Install the Fyne toolkit and its dependencies by following the instructions on the [Fyne website](https://developer.fyne.io/started/).
+
+Once Go and Fyne are set up, navigate to the project directory in your terminal and run the following command to build the application for Apple Silicon (ARM64) macOS:
+
+```sh
+GOOS=darwin GOARCH=arm64 fyne package
+```
+
+This will create a `TurtleSilicon.app` file in the project directory, which you can then run.
+
+Make sure you have an `Icon.png` file in the root of the project directory before building.
+
+## Bundled Binaries
+
+The `rosettax87` and `winerosetta` (d3d9.dll) components included in this application are precompiled for convenience. If you prefer, you can compile them yourself by following the instructions provided by LifeIsAwful on the official `winerosetta` repository: [https://github.com/Lifeisawful/winerosetta](https://github.com/Lifeisawful/winerosetta)
