Unlike Linux handhelds, the Ayn Odin 2 does not use a separate "custom firmware" — it runs stock Android, and you customize the experience with front-ends layered on top. The usual setup is to install RetroArch (use the stable build, not the Google Play version) and your emulators, then add a launcher like ES-DE or Daijisho to organize games with box art and a console-style menu. These come from normal app sources and need no rooting or unlocking. You can set the front-end as your home app for a console feel, and still drop back to Android whenever you want.

FAQ

Is there a Linux custom firmware for the Odin 2?
For everyday use, no — the Odin 2 is an Android device and the supported path is front-ends like ES-DE or Daijisho over stock Android, not a Linux CFW.
ES-DE or Daijisho — which front-end should I use?
Both work well. Daijisho is light and quick to set up; ES-DE offers deep theming and scraping. Try one, and keep RetroArch as the underlying emulator.
