GammaOS Nano is the console-style interface at the heart of GammaOS, a customized Android firmware for handhelds. It is the first thing you see when the device starts, and it is far more than a launcher: it has its own built-in music, photo, and video players, a controller-friendly web browser, IPTV and internet radio, network shares, and the full system settings, all wrapped in a smooth, console-like home.
Because GammaOS is a full firmware, Nano is tied into the system itself: brightness, performance modes, shaders, controller remapping, RGB lighting, and audio tuning are all reachable from the same interface. Think of it as the front door to your handheld, built to feel smooth and console-like, to look great at any screen size or orientation, and to stay out of your way when you just want to play.
How the home screen works
The home is organized into a small set of categories that you move between. On the GammaOS XMB theme they sit across the top of the screen, and the items for the selected category drop down in a vertical list beneath it. Move sideways to change category, and up or down to move through the items.
The categories are:
| Category | What is inside |
|---|---|
| Settings | The full settings tree: themes, network, display, sound, gamepad, and more. |
| Photo | Your pictures, in a full-screen viewer with a thumbnail grid and slideshow. |
| Music | Albums, playlists, and tracks, with a now-playing screen and internet radio. |
| Video | Your videos and folders, plus a full player and live IPTV channels. |
| Game | Your games grouped by system, plus your apps, collections, and recently played. |
| Network | Wi-Fi and Bluetooth setup, plus your SMB, NFS, WebDAV, and FTP shares. |
You can reorder or hide these categories to suit how you use your device. See Settings Reference for the Home Categories option.
Three themes at a glance
GammaOS Nano comes with three switchable looks, and they all drive the same interface underneath:
- GammaOS XMB, a PlayStation 3 style layout with a flowing wave background and glass icons.
- DSi Menu, a Nintendo DSi style carousel of glossy tiles.
- Minima, a clean, minimal text list on a black canvas.
Switch between them any time in Settings > Theme Settings > Home Theme. For the full breakdown of each one, see Home Themes.
What it does
Nano gets you into your games and media fast, and handles a lot itself along the way:
- Games run through emulators, either RetroArch cores or standalone emulator apps. See Emulators.
- Nintendo DS games use the built-in DraStic Nano emulator.
- Media (music, photos, and video) plays right inside Nano, with its own players. See Media.
- Web, radio, and TV: a controller-friendly browser, internet radio in Music, and live IPTV channels in Video are all built in.
- Network shares over SMB, NFS, WebDAV, and FTP mount as if they were local storage. See Network Shares.
- Apps you install appear in the Game category and launch just like a game. See Applications.
When you exit a game, an app, or a media player, you come straight back to the home where you left off.
