🎮 OmniEmu v0.1.3 — Fourth Pre-Release

Cross-platform emulator manager, game launcher, and ROM library manager.

Thank you to everyone testing OmniEmu! This release introduces frontend support, automatic ROM detection, improved emulator discovery, and plenty of quality-of-life improvements.

✨ What's New

🖥️ Frontend Support

OmniEmu now supports installing and configuring multiple emulation frontends alongside your emulators.

ES-DE (EmulationStation Desktop Edition) (Beta)

A polished multi-system frontend for browsing and launching your game library.

  • Automatic configuration with your ROM library
  • Detects installed emulators automatically
  • Supports all 20+ systems available in OmniEmu
  • macOS: Manual installation required (OmniEmu walks you through the process)

NeoStation (Beta)

A modern Flutter-based frontend focused on simplicity and ease of use.

  • ScreenScraper integration
  • Automatic emulator and ROM detection
  • Built-in RetroAchievements support
  • macOS: Manual installation required (guided by OmniEmu)

EmuBuddy

An easy-to-use frontend focused on getting you playing quickly.

  • Automated setup
  • One-click controller configuration
  • Automatic game downloading
  • Supports 14 systems
  • Available on Windows, macOS, and Linux

Pegasus Frontend (Beta)

A lightweight, highly customizable frontend with extensive theme support.

OmniEmu automatically:

  • Generates metadata.pegasus.txt collection files
  • Configures Pegasus to use your ROM library
  • Creates launch commands for supported emulators
  • Keeps collections organized automatically

🧪 Experimental Features

A new Settings → Experimental page lets you enable beta functionality.

Turning on Beta Features unlocks:

  • ES-DE
  • NeoStation
  • Pegasus Frontend

EmuBuddy is available by default and does not require the beta toggle.

📚 Automatic ROM Library Scanning

The Library page is now ready as soon as OmniEmu starts.

If your ROM directory is configured (default: ~/Documents/roms), your games will appear automatically—no manual folder selection required.

📝 Pegasus Collection Generation

When Pegasus is configured (or when OmniEmu starts with Beta Features enabled), collection files are automatically generated inside each ROM folder.

Example:

roms/
└── nes/
    └── metadata.pegasus.txt

Each generated collection includes:

  • Collection name
  • Short name
  • Supported file extensions
  • Launch commands
  • Individual game entries

No manual configuration required.

🛠️ Improvements & Bug Fixes

🍎 Better macOS Frontend Installation

Because ES-DE and NeoStation require manual installation on macOS, OmniEmu now provides a guided installation experience.

It can:

  • Detect downloaded DMG files
  • Open the installer automatically
  • Detect when installation is complete
  • Continue setup without extra configuration

Prefer to install it yourself?

A new Install Manually button lets you skip the guided process at any time.

🔍 Improved Emulator Detection

Finding existing emulator installations is now much more reliable.

Improvements include:

  • Homebrew support
  • Snap support
  • Flatpak support
  • Common installation directories
  • Recursive binary scanning

📂 Smarter ROM Detection

ROM scanning has been significantly improved.

Highlights:

  • ROMs are automatically organized into their correct system folders
  • Better platform detection
    • For example, .iso files inside a ps2/ folder are now correctly identified as PlayStation 2 instead of PlayStation
  • Added support for:
    • .cdi (Dreamcast)
    • .pbp (PSP)
    • .chd (multiple systems)
