Lattice Weaver
The Windows companion app handles player slots, guided setup, device assignment, profile selection, and adapter connections.
Minecraft master controls
Player 0 can adjust routed-player Minecraft settings from a purpose-built in-game control screen.
Paralives adapter
Route another player's input into Paralives while your native Windows controls remain available.
Developer devkit
Build game adapters against the public adapter surface. Weaver remains closed-source; the devkit contains schemas, samples, and SDK libraries.
