The Quick Menu is your fast lane to the settings you reach for most: brightness, performance mode, shaders, USB mode, and power options. You can open it from the home, and you can raise it right over a running game without quitting.

Opening the Quick Menu
- On the home, the Quick Menu is the far-left category (the power-icon column). Move to it like any other category.
- Over a running game or app, hold Power to raise the Nano overlay, which opens straight on the Quick Menu. Press B or hold Power again to drop back into your game. See the in-game overlay.
- Holding Power on the home jumps directly to the Quick Menu's Power submenu.

Performance Mode
Three profiles trade battery for speed:
- Normal scales up and down with load (the everyday default).
- Max Performance holds high clocks for the most demanding games.
- Power Saver keeps clocks low for light emulation and long sessions.
Global Shaders
The Global Shaders item applies a system-wide display shader over everything on screen. Pick a preset and tune it:
- Off turns shaders off.
- CRT adds scanlines (adjust Scanline Size and Scanline Strength).
- LCD3x and LCD emulate an LCD grid.
- Blur Fill fills the empty sides of a non-fullscreen image (with a Resolution and Orientation control).
- Custom Shader loads your own preset, with Resolution Scale and Scanline Density controls.
If a shader ever makes the screen unreadable, hold Power + Select to disable it instantly. See Controls.
Quick Settings tiles
The Quick Settings page is a grid of one-tap toggles, including Wi-Fi, Bluetooth, Performance Mode, Global Shaders, GammaRGB, GammaEQ, Screen Map, Deep Sleep Mode, External as Primary, Immersive Mode, ABXY Swap, D-Pad/Analog Swap, Global Sensitivity, Analog Calibration, and stick inversion. Tap one to flip it.
USB Settings
Switch how the device appears when plugged into a computer:
- Charging only (default): no data connection.
- MTP: browse the device's files as media storage.
- PTP: transfer photos.
- RNDIS: share the device's connection as USB Ethernet.
