MinUI on the Miyoo Mini Plus

International Superstar Soccer running on a SNES emulator within the MinUI launcher.

Having spend just a few hours with MinUI on my Miyoo Mini Plus, I already prefer it over OnionOS (or the stock firmware, for that matter).

What is MinUI?

It’s an alternative, minimalist launcher for the Miyoo Mini Plus (and the RGB30, Trimui Smart (and Pro), Miyoo Mini, M17, and Anbernic RG35XX) that took a lot of inspiration of the Analogue Pocket’s Analogue OS.
Out of the box (the MinUI-20231126b-2-base.zip) it supports Game Boy, Game Boy Color, Game Boy Advance, Nintendo Entertainment System, Super Nintendo Entertainment System, Sega Genesis & PlayStation 1. With the MinUI-20231126b-2-extras.zip there is also support for Neo Geo Pocket (and Color), Pico-8, Pokémon Mini, Sega Game Gear, Sega Master System, Super Game Boy, TurboGrafx-16 (and TurboGrafx-CD) & Virtual Boy.

Make sure to visit the https://github.com/shauninman/MinUI/releases page to download the latest version of the launcher.

If you want some additional tools for MinUI you can get those from https://github.com/westoncampbell/MiyooMini/releases/tag/MiniUI-OnionPAKs. This pack has an audio player, some alternative file browsers, a terminal emulator, a screenshot tool and more.

If you migrate from Onion OS to MinUI, you might have to rename your save files. In my case I had to rename my mGBA saves from .srm to .gba.sav. I don’t know if this is needed for other emulators.
