OpenEmu Deployment and Usage Guide

Prerequisites

• macOS: Mojave 10.14.4 or later (for building the default branch)
• Xcode: Version 14.3 or later (for building the default branch)
• macOS Version: Ventura or later (for building the default branch)

Installation

1. Clone the repository:

   git clone https://github.com/OpenEmu/OpenEmu.git
   cd OpenEmu
   

2. Open the project in Xcode:

   • Navigate to the cloned directory
   • Open OpenEmu.xcodeproj in Xcode

3. Build the project:

   • Select the appropriate scheme (OpenEmu)
   • Choose your target device (macOS)
   • Click the Build button (or press Cmd+B)

Configuration

OpenEmu does not require additional configuration files or API keys for basic usage. However, you may want to:

• Set up your game library location
• Configure controller settings
• Adjust video and audio preferences through the application's preferences panel

Build & Run

Development Build

1. Build the project:

   # In Xcode, press Cmd+B or use Product > Build
   

2. Run the application:

   • Press Cmd+R or use Product > Run
   • Alternatively, build and run directly from Xcode

Production Build

1. Archive the application:

   • Use Product > Archive in Xcode
   • This creates a signed application bundle

2. Distribute the application:

   • Export the archive as a macOS application
   • Distribute via your preferred method (App Store, direct download, etc.)

Deployment

OpenEmu is a macOS application and should be deployed as follows:

• Direct Distribution: Distribute the .app bundle directly to users
• App Store: Submit to the Mac App Store (if you have distribution rights)
• GitHub Releases: Create releases on the OpenEmu GitHub repository with the built application

Note: OpenEmu is an open-source project, so distribution should comply with its license terms.

Troubleshooting

Common Issues and Solutions

1. Build Failures:

   • Issue: Xcode build fails with missing dependencies
   • Solution: Ensure you have the correct version of Xcode (14.3+) and macOS (Ventura+)

2. Runtime Errors:

   • Issue: Application crashes on launch
   • Solution: Check system requirements (macOS Mojave 10.14.4+) and ensure all dependencies are met

3. Game Compatibility:

   • Issue: Games not loading or running incorrectly
   • Solution: Verify that the correct core plugin is installed for your game system. OpenEmu supports multiple emulation cores for each system.

4. Controller Issues:

   • Issue: Controllers not being detected
   • Solution: Check OpenEmuSystem framework integration and ensure controllers are properly connected and configured

5. Library Import Problems:

   • Issue: Games not importing correctly
   • Solution: Check file permissions and ensure game files are not corrupted. Refer to the import operation code in ImportOperation.swift

6. UI Display Issues:

   • Issue: Interface elements not displaying correctly
   • Solution: Check for any issues with the appearance preferences and ensure your macOS version is compatible
