Onion is a custom operating system overhaul for the Miyoo Mini and Mini+ retro handheld consoles, built in C. It bundles 100+ emulators, a custom RetroArch build, save/resume, themes, and quality-of-life features like GameSwitcher and activity tracking.

Use cases

  • install custom OS on Miyoo Mini
  • retro game emulation on handheld
  • auto-save and resume retro games
  • customize handheld console UI with themes
  • run native ports on Miyoo Mini+
  • track retro gaming play activity

When to choose

  • you own a Miyoo Mini or Mini+ and want a polished emulation experience
  • you want instant save/resume and fast game switching on a handheld
  • you want community themes and a large built-in emulator set

When to avoid

  • you use a different handheld device than the Miyoo Mini/Mini+
