Tool Switch Frame Tap: play your Switch on a PC at native 1080p 60 fps over USB, no capture card (works on Switch Lite)
Enable HLS to view with audio, or disable this notification
I've been building an Atmosphère sysmodule plus a PC viewer (Windows, Linux, macOS) that streams the game you're playing to your PC, with sound, over a USB-C cable or Wi-Fi.
It's different from SysDVR: instead of the console's 720p30 recording stream, it copies the game's finished frames and encodes them with the Switch's hardware H.264 encoder, so you get the game's own resolution at 60 fps (720p handheld, 1080p docked or with ReverseNX-RT), about 45-60 ms from game to screen.
Good for:
- a "dock" for the Switch Lite, or playing on a big screen without a dock
- recording gameplay to MP4 without a capture card
- native-resolution screenshots on a button combo
- webcam mode: the Switch shows up as a USB camera in OBS or Discord
Firmware 21 to 23. It's free and open source, and on the Homebrew App Store too.

Edit: AI assisted development disclosure:
This is fully disclosed on the repo but I will include it here too. This project was created with Claude, I have been working on this for over two months but it is AI assisted development! I know this is a deal breaker for some people, so if you are against AI being used for things like this just don't use it.
Feedback and bug reports are very welcome.
