Epoch Silicon

A user-friendly launcher for Project Epoch on Apple Silicon Macs, with one-click patching of winerosetta, rosettax87 and d9vk.

Features

• Apple Silicon Compatibility: Runs 32-bit DirectX9 World of Warcraft (v3.3.5a) on M1/M2/M3/M4 Macs without "illegal instruction" errors.
• Performance Optimization:
  • Integrates rosettax87 for accelerated x87 FPU instructions
  • Uses d9vk for efficient DirectX9 via Vulkan/Metal translation
  • Achieves significant FPS improvements
• Automated Setup: One-click patching for both CrossOver and Epoch installations.
• Simple Interface: Easy to use GUI with status indicators and configuration options.

Known Issues

• For one tester, it took up to a minute for Wow to start after hitting the "Play" button. This is currently being investigated.

Usage

Prerequisites

Before you begin, ensure you have the following:

• A working version of CrossOver installed (the trial version is sufficient and can still be used after expiration).
  • You must use CrossOver v25.0.1 or later. Older versions will cause issues.
• A 3.3.5a World of Warcraft client. You can download the client from Project Epoch's download page
• Place the client in a folder you have rights to. Your user directory (example: /Users/username/Epoch) is a good default choice. Avoid spaces in your path!

Installation

1. Click here to download the latest release.
2. Double-click EpochSilicon.dmg.
3. Drag EpochSilicon into Applications. You may now close and eject the disk image.
4. Run EpochSilicon like you would any other application using Launchpad, Shortcut, etc.

Setup

1. Launch EpochSilicon.
2. Set CrossOver Path:
   • If CrossOver is installed in the default location (/Applications/CrossOver.app), this path will be pre-filled.
   • Otherwise, click "Set/Change" and navigate to your CrossOver.app bundle.
3. Set Warcraft Directory Path:
   • Click "Set/Change" and select the folder where you have your WoW 3.3.5a client files.
4. Apply Patches:
   • Click "Patch Epoch".
   • Click "Patch CrossOver".
   • Status indicators will turn green once patching is successful for each.
5. Start RosettaX87 Service:
   • Click "Start Service" and enter your sudo password when prompted.
   • This will run the RosettaX87 service in the background and is required for launching the game.
   • The service will automatically stop when you close the launcher.
6. Configure Options (Optional):
   • Enable Metal Hud: Shows FPS counter in-game.
   • Show Terminal: Displays terminal output during game launch for debugging.
7. Launch Game:
   • Once both paths are set, both components are patched, and the RosettaX87 service is running, the "Launch Game" button will become active. Click it.
8. Enjoy: Experience a VM free, smoother Project Epoch on your Apple Silicon Mac!

Troubleshooting / FAQ

The Patch Epoch step is taking forever

The initial patch download is quite large and can take a while if your internet is slow. The app will tell you when it's done.

My resolution is super blown up and I can't see the whole screen

Wine does that on first launch if you have a large widescreen monitor.

1. Hit Escape to close the game
2. Open your Config.wtf file in a text editor, it is located in your wow game directory at /WTF/Config.wtf
3. Add your desired resolution. I have a 3440x1440 monitor so I added the following to my Config.WTF

SET gxResolution "3440x1440"

When I change graphics settings, all the buttons have big white boxes around them

This is another common wine issue, just close the game normally and it should be fixed on next startup

Running from Source Code

If you prefer to run the application directly from source code:
