Sound in sync with the picture, File Transfer, and night brightness.
- Sound in sync: game audio trailed the picture by about 200 ms (274 ms on GBA). It now sits around 67 ms on every device, in line with Onion, muOS, Knulli and NextUI, at the same low clocks.
- Cleaner sound (TrimUI): game audio goes straight to the sound chip, WiFi turns off while a game runs (it caused crackle), and the CPU speeds up the moment the sound buffer runs low.
- File Transfer (TrimUI): Tools > File Transfer moves files to and from your computer four ways: USB Drive, USB (MTP), FTP over WiFi, or a browser page.
- Night brightness: steps darker than the backlight's minimum, for reading in bed. Seven on TrimUI, four on Miyoo Mini Plus.
- WiFi: network names and passwords with spaces now work, and dev cards show the WiFi on/off row in Settings.
- Anbernic: powers off cleanly when the battery is empty and protects the card on power-off.
Copy MinUI.zip to the card root to update. Anbernic: flash the image.
