To enable split-screen play in Minecraft on the Wii U, follow these steps:
Ensure the Wii U is connected to the TV using High Definition mode (720p or higher).
Start Minecraft and select Play a Game, then press the A Button to load or create a game.
While the game is playing on the TV, the second player should press the +Button on the Wii U Pro Controller to activate multiplayer mode.
If the game is in Off-TV Mode, click the TV Mode icon on the bottom-right of the GamePad screen.
The GamePad should display a Minecraft block. The second player selects a character and presses the A Button to join the game.
It's important to note that only a Wii U GamePad and Wii U Pro Controller or Wii Classic Controller can be used in multiplayer mode.
Additionally, third-party Pro Controllers might not work properly in Minecraft for Wii U.
