LibNXbox
What it is
LibNXbox is free GPL-2.0 homebrew software for streaming from an Xbox console or Xbox Cloud Gaming to a Nintendo Switch. The project distributes libnxbox.nro through GitHub releases, and the NRO must run in title mode; applet mode crashes. For home streaming, it discovers the console in the same way as xbox.com/play. The README describes launching xCloud games through a Moonlight Switch NRO forwarder by entering a game AppID. LibNXboxNROHelper can search the Microsoft Store and create game-art thumbnails plus a titles.txt file with game names and xCloud AppIDs. The listed stream uses 1280×720 H.264 video with Tegra X1 NVDEC decoding, and Opus stereo audio at 48 kHz in a WebM container with an approximately 60 ms latency target. Switch face buttons map by physical position, while digital ZL and ZR register fully pressed or released. Haptics are implemented, with rumble strength reduced by 50%. Microsoft handles authentication; a token is stored on the SD card. The app does not show queue times or bypass service restrictions.
