Switch 2 Joy-Cons rebuilt in Wii Remote shells, magnetically dock to console
↗
YouTuber Kouzex transplanted Joy-Con 2 internals into two Wii Remote shells, creating motion controllers that magnetically attach to a Switch 2 and work in all games.
This mod demonstrates the feasibility of repurposing legacy controller shells for new hardware, but it requires significant soldering and custom wiring, including harvested connectors and extended cables. The result sacrifices the Wii Remote's original functionality and the release button, and the Joy-Con 2's potentiometer sticks remain drift-prone. For engineers, it highlights the constraints of fitting modern components into older form factors and the workarounds needed for incompatible connectors and voltages.

Each Joy-Con 2 contributes only its motherboard, thumbstick, magnetic rail, battery, and HD rumble motor to the build.
The stick's short ribbon cable required a harvested connector from a dead first-gen Joy-Con and soldered wire extensions.
The modified Wii Remotes lose Wii compatibility and the release button, so controllers are removed by hand.
