  • A to select, B to close modals

  • Auto-focus on page change

Bug Fixes

  • Emulator launch command injection — replaced exec() with spawn() for all emulator and game launches, preventing shell argument injection
  • RetroAchievements password — encrypted on disk using Electron safeStorage
  • Single-instance lock — bypass fix prevents second instance from ignoring the lock
  • Sandbox flags — --no-sandbox and --disable-gpu-sandbox now only applied on Steam Deck
  • Controller detection — fixed Xbox L2/R2 axis mapping (axes +4/+5), fixed button/axis comparison including both arrays
  • RetroArch presets — removed hardcoded audio_driver = "pulseaudio" from both presets
  • Save file extension — fixed .SVS → .svs case sensitivity in save detection
  • URL scraper — urlExists() now follows 301/302 redirects (up to 5 deep)
  • Game detail modal — fixed prop mutation on coverUrl (now uses local state)
  • UtilitiesPage — fixed window.omni.emu → window.omni.emulators
  • Error boundaries — all 8 pages wrapped with ErrorBoundary for graceful crash recovery
  • RetroArch save detection — now finds saves in core subdirectories and supports portable installs
  • Syncthing install — fixed macOS extraction from nested zip directory, updated to v2.1.2
  • Syncthing blue screen — fixed IPC handler crashes, pipe buffer deadlock, null device ID crash
  • Cloud Sync poll leak — start polling now cleans up on unmount
  • 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 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

System Requirements

  • Disk: ~200 MB for app + emulators vary
  • RAM: 4 GB minimum
