I’ve released OneOS, a simple OS for retro handheld consoles with multi-language display support.

retronian/OneOS: OneOS is a focused, custom launcher and libretro frontend for a variety of retro handhelds.

It’s basically a fork of MinUI with multi-language support added. (English, Japanese, Simplified Chinese, Traditional Chinese, Korean, French, Spanish)

You can switch languages via “Settings” > “Language”.

I also added a screenshot feature.

I’ve only tested it on the Miyoo Mini+ so far, but I think it should work on any device that ran MinUI — so if you try it and it works, I’d love to hear about it!

I’m also not super confident about the languages other than English and Japanese, so if anything looks off, please let me know — I’d really appreciate it.
