Global Shortcuts

Click here to see an overview of all global shortcuts.

 

GameSwitcher

The GameSwitcher is designed to be the central user interface of Onion. Launch the GameSwitcher by pressing the MENU button. The last game played will be resumed in a few seconds, and with the simple press of a button, save your progress and turn off the console.
It also allows you to quickly change games and many other features:

  • Quick boot your last played game.
  • Quickly switch games from your history.
    • Remove a game by pressing X.
  • Full overlay with accurate brightness, battery readings and playtimes.
    • Press SELECT to toggle playtime display.
  • Minimal view mode: Press Y to toggle.
  • Improved Sleep Mode with full game suspension (press POWER).
  • Low battery indicator: Red frame when <15% (can be adjusted in Tweaks).
  • When the battery goes below 4%, the device will automatically save and exit to prevent losing progress.

 

Package Manager

  • Choose the systems and apps you need.
  • Optimized presets, homebrew apps, and more.
  • Packages are divided into three sections:
    • Verified: Contains all verified systems (see Emulators for more information).
    • Apps: Contains all the included Onion and third-party apps.
    • Expert: Contains experimental/expert systems (see Emulators for more information).
  • To reinstall a package, first toggle it off and press START to apply, then open Package Manager, toggle it on and apply.

 

Tweaks

Make Onion your own!

  • System settings: Startup behavior, auto-save and exit, vibration
  • Custom shortcuts: Single/long/double press MENU, and launch apps or tools via X or Y in MainUI
    • Known limitation: Some apps can't be launched this way (for now only Music Player / GMU is known not to support this)
  • User interface: Show/hide recents/expert tabs, theme overrides
  • Advanced: Quick access to advanced emulator settings, plus a submenu to reset different settings
  • Tools: Sort favorites, fix thumbnails, remove OSX system files

 

Search

  • The Search app lets you search all your games.
    • Note: For now only verified systems are supported (the ones that are in the Games tab).
  • You'll find Search under Apps - and it's a popular choice for mapping to X or Y (via Tweaks).
  • When a search is active, the results will be shown under Games › Search, you can remove the search again by choosing "Clear search".
  • "Missing caches" lists all systems which haven't been cached yet, and thereby haven't been included in the search.
    • Reason: All game caches are cleared everytime you "Refresh all roms".
    • Solution: Go into each system you want included in the search.

Filter

  • Filter is available via Package Manager › Apps, installing it will add the following shortcuts at the bottom of each game list:
    • Filter: Will prompt you to enter a keyword for filtering the selected game list.
    • Refresh roms: Will refresh roms only for the selected game list.
  • Note: If you're using a miyoogamelist.xml you will need to add an entry for ~Filter.miyoocmd and ~Refresh roms.miyoocmd.

 

Themes

 

Activity Tracker

  • Track your game playtimes (format h:m).
  • View your total playtime in the top bar (format h:m).
  • Share your playtimes by taking a screenshot (press MENU+POWER - screenshot is saved in Screenshots).
