What LibNXbox is
LibNXbox is a free Nintendo Switch client for streaming from an Xbox console or Xbox Cloud Gaming. For console streaming, its NRO must run in title mode, where it discovers the console; applet mode crashes. To start an xCloud title, the README describes using a Moonlight Switch NRO forwarder and entering the game's AppID. The companion LibNXboxNROHelper can search the Microsoft Store and generate game-art thumbnails and a titles.txt file containing game titles and xCloud AppIDs. The listed stream setup is 720p H.264 video with Tegra X1 NVDEC hardware decoding and stereo Opus audio at 48 kHz. Switch face buttons map to Xbox buttons by physical position, while digital ZL and ZR register as fully pressed or released. Authentication uses Microsoft's official servers, and the app saves a token on the SD card. It does not show queue status or waiting times, and does not bypass xCloud availability, subscription, bitrate, or game-ownership requirements. The project lists a GPL-2.0 license and says it is provided without warranty.
