Hotfix for v1.4.0.
- NES/GB/GBC/SMS/GG/PCE pacing: rare 55-58fps dips gone; ceiling holds at 1008 MHz, chip still idles at 408.
- NES sound: old saved configs migrate off upstream's expensive High setting to Low.
- Menu and HUD: the in-game menu is ~2x snappier, the governor returns cleanly after sleep or menu, and a bindable Toggle HUD was added.
The experimental frame-sync smoothing from v1.4.0 is off by default again. Copy MinUI.zip to the card root to update.
