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
