OmniEmu v0.2.0 fith prereleases Pre-release

Pre-release

mileswolfallen2 released this 14 Jul 05:51

v0.2.0

e1db14b

🎮 OmniEmu v0.3.0

✨ All your games. One place. ✨

Hey everyone! We're super excited to bring you v0.3.0 — this is a big one. We've been working hard on a bunch of features you've been asking for, squashed a ton of bugs, and made the whole experience feel a lot more polished. Let's dive in! 🚀

🗂️ Save Manager

Ever lost a save file because you forgot which folder it was in? Yeah, us too. That's why we built the Save Manager!

Open the new 💾 Saves tab in the top bar and you'll see all of your emulator save files and save states, neatly organised by game. Here's what you can do:

Browse — saves are automatically scanned from your RetroArch, Dolphin, RPCS3, PCSX2, DuckStation, Flycast, PPSSPP, and Eden directories
Fuzzy matching — OmniEmu intelligently matches save files to the games in your library, even if the filenames don't line up perfectly
Back up — one-click backup of any save file so you never lose progress
Delete — clean up old or unwanted saves right from the app
Custom directories — point each emulator at a custom save folder if your setup is a little different

It's like a file manager, but actually enjoyable to use. 😄

🖥️ Frontend Options

OmniEmu now supports four emulation frontends! Whether you want a plug-and-play experience or full customisation, there's something for you.

EmuBuddy

Available on all platforms — no toggles needed. EmuBuddy gives you one-click setup, built-in game downloading, and full controller support. Just install and go!

ES-DE (Beta)

The beloved EmulationStation Desktop Edition is here. It's a gorgeous multi-system launcher with tons of community themes. Enable Beta Features in Settings to unlock it.

🍎 macOS note: ES-DE requires a manual install via DMG because of license acceptance requirements — we'll show you exactly what to do!

NeoStation (Beta)

A modern Flutter-based frontend with built-in ScreenScraper integration for automatic game art and metadata. Also behind the Beta Features toggle.

🍎 macOS note: Same deal as ES-DE — manual DMG install, but we walk you through it.

Pegasus Frontend (Beta)

Love customisation? Pegasus is a fully themeable launcher that puts you in control. And the best part? OmniEmu automatically generates collection files for Pegasus — just scan your ROMs and everything shows up. We write metadata.pegasus.txt files into each ROM subdirectory and a central settings.txt so Pegasus knows exactly where to look.

🎨 SteamGridDB Cover Art

Your game library deserves to look good! 🖼️

OmniEmu now integrates with SteamGridDB for high-quality cover art. Here's how it works:

Grab a free API key from steamgriddb.com and pop it into Settings
When viewing a game, hit "Change Cover" and search SteamGridDB right from inside the app
Pick the cover you like and it's saved locally — works offline too!
Don't like it? Hit "Reset Cover" to clear it and fall back to free art sources

All images are downloaded through the main process, cached locally as file:// paths, and rate-limit retries are built in so we don't get blocked. No more broken cover art! 🎉

🎨 Four Brand-New Themes

We've gone from 3 themes to 7! 🌈

Theme	Vibe
Midnight	Deep dark blues and purples — easy on the eyes for those late-night gaming sessions
Ember	Warm oranges and reds — cozy and inviting
Lavender	Soft purples and pastels — calm and elegant
Jade	Cool greens and teals — fresh and modern
Dark	Classic dark mode
Light	Clean and bright
System	Follows your OS preference

You'll find them all in Settings → Appearance → Theme.

🕹️ Horizontal Navigation & Gamepad Support

The old sidebar is gone — say hello to the new top bar navigation! 🎉

Tabs run horizontally across the top: Home, Emulators, Library, Saves, Controller, Utilities, Settings
Full gamepad navigation — D-pad left/right switches tabs, A selects, B closes modals
Smart auto-focus — when you switch tabs, the first interactive element lights up automatically
The "Launch Game" button in the game detail modal auto-focuses so you can hit A and start playing immediately

The whole UI feels snappier and more controller-friendly than ever. 🎯

⬆️ Improvements

Here's everything else we've improved since v0.2.0:

🗂️ BIOS folder skip — the ROM scanner now automatically skips folders named "bios" so your BIOS files don't get mixed in with your games
Controller auto-focus — the game detail modal now auto-focuses the "Launch Game" button for controller users
Reset Cover — clear a downloaded cover and fall back to the free art sources (libretro thumbnails, MobyGames)
macOS RetroArch — removed the broken cores download (it was 404). Cores must be downloaded from within RetroArch's Online Updater after installation
Gamepad resilience — improved error handling in the controller navigation polling loop so one bad frame doesn't break your whole session

🐛 Bug Fixes

We squashed quite a few bugs this release:

SteamGridDB 404 fixed — the search API endpoint was wrong (/search/game/ → /search/autocomplete/). Cover art search works again!
Cover images not loading — Electron's renderer can't load remote images due to CORS. We now download thumbnails through the main process and serve them as local file:// paths
Theme colours broken — hardcoded accent colours (rgba(0, 212, 255, ...) and rgba(124, 58, 237, ...)) were causing glow effects to look wrong on non-default themes. All glow effects now use CSS color-mix() with var(--accent) so they adapt to every theme
Duplicate .platform-tag CSS — the muted tag style on emulator cards was being overridden by the accent variant in the game detail modal. Renamed the accent variant to .platform-tag-accent
Stale types.d.ts — removed an outdated type declaration file that could shadow the real types.ts definitions
Inline require() calls — replaced 7 instances of require('fs') and require('os') in the emulator registry with proper ES module imports
Duplicate require('electron') — removed a redundant inline require in the save manager IPC handler (it was already imported at the top)
Unused imports — cleaned up isLinux from emulators.ts and EmulatorConfig from SettingsPage

📋 Supported Emulators

We now support 14 emulators and 4 frontends! 🎉

📝 Good to Know

A few handy tips for this release:

Beta Features — ES-DE, NeoStation, and Pegasus are in beta. Head to Settings → Experimental → Beta Features to enable them.
SteamGridDB — Cover art search needs a free API key. Sign up at steamgriddb.com and enter it in Settings.
macOS frontends — ES-DE and NeoStation require a manual DMG install because of license acceptance requirements. We'll show you a handy guide right in the app!
RetroArch cores on macOS — After installing RetroArch, open it and use the Online Updater to download cores. OmniEmu handles everything else.
Azahar — This is the successor to Lime3DS (which was itself the successor to Citra). If you used Citra before, this is the one you want.

🙏 Thank You!

Happy gaming! 🎮✨

OmniEmu v0.1.3 — Fourth Pre-Release Pre-release

Pre-release

mileswolfallen2 released this 13 Jul 06:43

v0.1.3

630deea

🎮 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)
