What Light is Green is

Light is Green is a free, open-source Cloud Play and Remote Play client for Nintendo Switch homebrew. It runs account authentication, game catalogue access, streaming, hardware video decoding, graphics, audio, and controller input on the console, without a companion PC. Its library shows cloud-playable games available to the signed-in Microsoft account, including Game Pass, eligible Stream Your Own Game titles, and free-to-play offerings. Streaming uses WebRTC and hardware H.264 decoding, with GPU presentation. Video options include 720p and 1080p, as well as 1080p HQ Windows and an experimental HQ Tizen profile; bitrate and pacing can be customized. An in-stream menu offers picture adjustments, while a HUD displays bitrate, frame rate, packet loss, and WebRTC ping latency. Switch controls can map to Xbox controls, with vibration and rumble support and Xbox Guide access. The client requires a Switch with Atmosphère custom firmware. The README directs users to launch in Title Mode because Applet mode lacks sufficient RAM for hardware decoding. Users must supply their own valid account and subscriptions. The project is non-commercial, for personal use, and distributed under GNU GPL v3.0.
