This is the GameShare (splay) applet added with 20.0.0, launched by qlaunch. See AM_services#Library_Applets.

Notes

This uses ldn to connect to the host. Video streaming is used.

Immediately after initializing ldn, SetProtocol is used with value 3.

There's various functionality where Ecc signature verification is used (public_key selected via spl IsDevelopment), this includes for verifying the AdvertiseData from the output of Scan.

On the client systems an Application icon entry is added with a GameShare icon, which is displayed by qlaunch (when there's no app-icon for the shared application already at least). This is just for launching eShop for the application.

During setup, the host transfers the game NACP to the client. JPEGs are transferred as well.
