OmniEmu v0.3.1 Release Notes

All your games. One place.

What's New

Cloud Sync (Beta)

Sync your game saves between devices using Syncthing — free, open-source, and fully local. No third-party accounts needed.

  • Install Syncthing directly from the app (one-click download)
  • Auto-starts on launch once configured
  • Host your device or pair with another to share saves
  • Manage shared folders and paired devices from the Cloud Sync tab
  • Web UI access for advanced configuration

Save Manager

Browse, back up, and delete game saves across all your emulators.

  • Dual view: By Game (fuzzy-matched titles) or By Emulator
  • RetroArch saves with recursive core-directory scanning
  • Custom save directories per emulator
  • Backup saves before deleting

New Emulators

Four new emulators added to the library:

Emulator System Platforms
Cemu Wii U Windows, macOS, Linux
xemu Original Xbox Windows, macOS, Linux
Vita3K PS Vita Windows, macOS, Linux
Azahar Nintendo 3DS Windows, macOS, Linux

Frontend Support (Beta)

Launch alternative frontends directly from OmniEmu:

  • ES-DE — full integration with auto-configuration
  • NeoStation — Flutter-based frontend with ScreenScraper integration
  • Pegasus — automatic collection file generation from your ROM library
  • EmuBuddy — available to all users (not behind beta toggle)

Decompilations (Beta)

Native PC ports built from reverse-engineered source code — bring your own ROM:

  • Ship of Harkinian (OoT), 2 Ship 2 Harkinian (MM), SoH Demo — Zelda
  • Portal 64, Banana Mania PC — additional ports
  • Auto-download from GitHub releases, built-in ROM management
  • Supported titles include N64, NDS, GBA, DS, Wii, GameCube, and more

Enable frontends and decompilations under Settings > Experimental > Beta Features.

SteamGridDB Cover Art

Search and set custom cover art from SteamGridDB's free API.

  • Search covers from the game detail modal
  • Thumbnails downloaded locally for instant display
  • Rate-limit aware with automatic retry
  • "Reset Cover" button to clear custom art

Themes

Seven themes available in Settings:

  • Light, Dark, System (auto)
  • Midnight — deep navy
  • Ember — warm dark
  • Lavender — soft purple
  • Jade — cool teal

Horizontal Navigation

Redesigned top-bar navigation with full gamepad/controller support:

  • Spatial D-pad navigation (up/down/left/right between elements)
  • A to select, B to close modals
  • LB/RB to switch tabs
  • Auto-focus on page change

Bug Fixes

  • RetroArch save detection — now finds saves in core subdirectories (saves/Snes9x/file.srm) and supports portable installs (~/Documents/RetroArch/saves/)
  • Syncthing install — fixed macOS extraction from nested zip directory, updated to v2.1.2
  • Syncthing blue screen — fixed IPC handler crashes, pipe buffer deadlock (stdio: 'pipe' → stdio: 'ignore'), null device ID crash in API response parsing
  • Cloud Sync poll leak — start polling now cleans up on unmount, loading state stays visible during startup
  • Cemu macOS — removed x64-only filter so it installs via Rosetta on ARM Macs
  • Vita3K macOS — added ARM64 DMG variant alongside x64
  • RetroArch cores 404 — removed broken RetroArch_cores.7z download (use RetroArch's Online Updater instead)
  • BIOS folder scan — scanRoms() now skips BIOS directories
  • CSS accent colors — replaced hardcoded colors with color-mix() using theme variables
  • Duplicate CSS — renamed .platform-tag conflict to .platform-tag-accent
  • Unused imports — cleaned up require() calls, dead imports, stale types.d.ts

System Requirements

  • OS: Windows 10+, macOS 11+, Ubuntu 20.04+
  • Disk: ~200 MB for app + emulators vary
  • RAM: 4 GB minimum

Supported Emulators (18 total)

RetroArch, Dolphin, RPCS3, Cemu, xemu, Vita3K, Azahar, Eden, PPSSPP, DuckStation, PCSX2, Flycast, Dolphin (trio), Yuzu (legacy), mGBA, MelonDS, and more.
