MiniUI is a custom launcher and integrated in-game menu for the Miyoo Mini handheld emulator

MiniUI is simple, some might say to a fault. That's okay. I think it's one of those things where, if you like it, even just a little bit, you'll love it. (For the uninitiated, MiniUI is a direct descendent of MinUI which itself is a distillation of the stock launcher and menu of the Trimui Model S.)

MiniUI is defined by no. No boxart. No video previews. No background menu music. No custom themes. No runners-up. MiniUI wants to disappear and speed you on your way. MiniUI is unapologetically opinionated software. Sorry not sorry.

The Miyoo Mini happened. The idea behind Union was the result of having a few of these handhelds but never being fully happy with any one of them in every context. One had a beautiful screen but was too heavy to carry casually. One was perfectly pocketable and had amazingly clicky buttons but the tiny screen wasn't great for long play sessions. So Union allowed easily moving games and save data between devices depending on context. Literally just swapping the SD card from one device to the other. But the Miyoo Mini is pocketable enough, its screen gloriously 640 by 480 enough, that I stopped using the other devices supported by Union. In a past life I learned not to develop features I won't use. Maybe I'll revisit the Union idea in the future or maybe the Mini will remain enough for a long while.
